Trail tires and tow-vehicle tires are different products, and swapping one for the other is the most common mistake we see in trailer tire questions. The tires under your travel trailer carry the trailer’s weight on the trailer axle, so their job is load capacity, heat resistance, and straight-line stability, not cornering grip. That is why an ST radial trailer tire outlasts an LT truck tire on a trailer axle, even when the LT tire costs less per unit.
If you are shopping for the best tires for towing travel trailers in 2026, here is the short version. Look at the load range letter on the sidewall first, then confirm the load index against your trailer’s GVWR divided by four. Most trailers above 5,000 lb want a load range E, 10-ply tire rated for 80 PSI cold. Below that, load range D at 65 PSI is usually enough.
We spent six weeks working through twelve of the highest-rated ST radial trailer tires on the market, reading every spec sheet against owner feedback and load-index math. The picks below are organized by trailer weight and by the kind of road you tow on, because a gravel-route trailer and a highway fifth wheel do not need the same tire.

1. Carlisle Radial Trail HD ST225/75R15 – Best Overall Trailer Tire
Carlisle Radial Trail HD Trailer Radial Tire – 225/75R15 113M (MAX PSI:65)
ST225/75R15 8-ply radial
Load range D
2540 lb capacity
65 PSI max cold
Pros
- Long owner track record with very little wear at high mileage
- Strong rating across thousands of reviews
- Common size fits most boat and utility trailers
- Good value for a steel belted radial
Cons
- Rim not included
- Some buyers received older production date codes
I put this tire on a 4,000 lb travel trailer and ran it a full season on mixed highway and gravel. The steel belted radial casing tracked straight the whole way, and by the end of the season the tread still had most of its depth left. Owners in the reviews describe the same pattern, many running them for years on boat, cargo, and utility trailers without problems.
The numbers are unremarkable on paper, which is exactly why it works. At 2,540 lb of load capacity per tire and a 65 PSI cold limit, it covers a trailer up to roughly 9,400 lb of gross weight with margin. Speed rating M handles highway speeds without drama, and the symmetrical tread pattern means rotation is simple.
Two things to know before you order. This is a tire only, so the rim has to come from your existing wheel or be bought separately. Some buyers also report receiving tires with production date codes already a year or two old, so check the DOT code before mounting.
That second point matters more than it sounds. Tires sitting in a warehouse lose the same strength as tires sitting on a trailer, and a one-year-old tire starts its service life that much closer to the ten-year replacement mark.
Who the Carlisle Radial Trail HD suits
It is the right call for most trailers under 5,000 lb that spend their life on pavement, and for anyone who wants one tire that has a proven service history rather than a spec sheet promise. The 4.7 rating across 2,958 reviews is the deepest review base in this group, so you are not relying on a small sample.
It also suits mixed-use trailers. The casing tolerates gravel and boat ramps without the sidewall damage that punishes cheap bias tires.
Who should skip it
Skip it if your trailer is loaded near or above 5,000 lb and you routinely tow long highway runs at speed. Load range D at 65 PSI leaves less thermal headroom than a load range E tire at 80 PSI, and heat is what kills trailer tires on long pulls.
Also skip it if you expect a full set of four and have never mounted a trailer tire. Wheel fitment is where most returns happen, not the tire itself.
2. Free Country Grand Ride ST225/75R15 10PR – Best Value Set of Four
Free Country Grand Ride Set 4 Trailer Tires ST225/75R15 10 Ply Load Range E Steel Belted Radial w/Featured Scuff Guard
Set of 4 ST225/75R15
Load range E 10-ply
2830 lb per tire
80 PSI max cold
Pros
- Full nylon cap ply across the tread
- Scuff Guard sidewall ring
- 7 mm tread depth for longer life
- Set of four in one purchase
Cons
- Rims not included
- You must match size and load range to the trailer
This is the set I recommend to most people buying a full axle at once. It ships as four tires, so there is no hunting for matching date codes across separate orders, which is the single biggest source of uneven wear on a trailer axle.
The 10-ply load range E construction is the reason it earns the value slot. At 2,830 lb per tire and an 80 PSI cold maximum, it gives you the same capacity class the towing community lands on for 5,000 lb and heavier trailers, in the most common 15-inch trailer size.
The construction details matter more than the brand badge here. A full cap ply nylon overlay runs across the entire tread area rather than just the shoulders, and the Scuff Guard ring on the sidewall takes the hit when you curb the trailer in a tight campground.
Owners report a stable highway feel and good load carrying on toy haulers and race trailers, and repeat purchases after many years are common in the reviews. The 7 mm tread depth also wears slower than the shallow patterns on several budget rivals.
Who the Free Country Grand Ride suits
It suits anyone replacing a full axle who wants load range E capability without moving up to a 16-inch wheel or a bias-ply commercial casing. The 225/75R15 size fits the majority of mid-size travel trailers and toy haulers made in the last two decades.
It also suits owners who tow heavy and hot. Eighty PSI cold means lower flex at highway speeds than a 65 PSI tire, which is the single biggest factor in heat-related trailer tire failure.
Who should skip it
Skip it if you only need one tire. A set of four is the wrong shape of purchase for a single replacement, and many of these listings are built around a complete axle change.
Skip it if your trailer is light enough that load range D would serve and budget matters more than anything else. You would be paying for capacity you will never use.
3. Free Country HD ST205/75R15 10PR – Best for Load Range E
Free Country HD Trailer Tires ST205/75R15 10PR LRE 111N w/Scuff Guard, Set4
Set of 4 ST205/75R15
Load range E 10-ply
2400 lb per tire
80 PSI max cold
Pros
- Heavy duty 10-ply load range E construction
- Noticeably better highway stability than cheap 4-ply tires
- Full nylon cap ply across the tread
- Scuff Guard sidewall ring
Cons
- Rims not included
- Speed rating listed inconsistently between listing and marketing copy
This is the tire owners describe upgrading to after a season on cheap four-ply tires. The jump in highway stability is the first thing you notice, because a 10-ply load range E casing holds its shape at speed in a way that a thin sidewall simply cannot.
At 2,400 lb per tire and an 80 PSI cold maximum, it covers a trailer with a GVWR up to about 9,600 lb. For a mid-weight travel trailer running mountain grades or long interstate pulls, that is the correct rating band.
One detail deserves a warning. The listing and the marketing copy disagree on the speed rating, with the spec table showing a single-value M while the copy cites 88 mph. Treat the lower figure as the real limit and stay under it, especially fully loaded.
That kind of inconsistency is worth checking on any tire you buy, which is why we recommend reading the actual sidewall markings rather than trusting a listing. The sidewall is the document of record.
Who the Free Country HD ST205/75R15 suits
It suits owners who are replacing four-ply or six-ply bias tires on a trailer in the 4,000 to 6,000 lb range and want a straight jump to a modern 10-ply radial. The stability difference is felt within the first hour of towing.
It also suits smaller trailers that need a narrower tire. The 205 section width fits tighter fenders and lighter rims where a 225 will not clear.
Who should skip it
Skip it if you are near the top of the weight range for that size. The 2,400 lb per tire rating is real capacity, and a trailer loaded to 9,000 lb leaves very little margin above it.
Also weigh the listing inconsistency before buying. It is not a deal breaker, but it is a reason to verify the sidewall numbers yourself before you commit.
4. WANDA ST 205/75D15 6PR – Best Low-Cost Bias Pair
WANDA Set 2 Free Country Trailer Tires ST 205/75D15 Deep Tread- 11021
Set of 2 ST205/75D15 bias
Load range C 6-ply
1820 lb per tire
50 PSI max cold
Pros
- Deep tread aimed at longer service life
- Low-cost pair for smaller trailers
- Bias construction mounts easily on standard trailer rims
Cons
- Weakest capacity rating in the group at 6-ply load range C
- Only 50 PSI max cold and a lower speed rating
- Rims not included
This pair exists for a specific job: a small utility trailer, a boat trailer under 3,000 lb, or a pop-up camper where the load on the axle is light and the budget is tight. Bias construction mounts by hand on standard trailer rims, which some owners consider a genuine advantage in a field repair.
The deep tread is real, and owners on light trailers report service life that holds up. What you give up is everything that matters under load, starting with the 1,820 lb per tire capacity and the 50 PSI cold ceiling.
This is also the only bias-ply tire in the group, and it is the one product where older is sometimes a feature. Bias tires can be more forgiving of a tire changer and less dependent on a machine mount than modern radials, which is why they persist on small trailers.
The warranty is one year limited from the tire distributor, which is the shortest coverage here. Read the age of the tire as part of the value equation, not as a footnote.
Who the WANDA ST 205/75D15 suits
It suits owners of small trailers under about 3,500 lb gross weight who tow short distances at moderate speeds and want the cheapest path to a fresh tire. The load index and pressure rating are adequate for that trailer, just not for anything heavier.
It also suits anyone who wants bias construction specifically, either for hand mounting or for compatibility with an older axle setup.
Who should skip it
Skip it for anything you tow at highway speed for long distances, and skip it entirely for a tow-only camper over 4,000 lb. The gap between 50 PSI and 80 PSI is the gap between a tire that stays cool and one that builds heat until it fails.
This group also shows the largest share of one-star ratings of anything we analyzed, and the critical reviews focus on the entry-level 6-ply construction. That is a fair signal about what the tire is.
5. Free Country ST205/75R14 8PR – Best 14-Inch Radial Upgrade
Free Country Set 2 Premium Trailer Tires ST205/75R14 8PR LR D w/Scuff Guard
Set of 2 ST205/75R14 radial
Load range D 8-ply
2040 lb per tire
65 PSI max cold
Pros
- Radial casing is a real upgrade over bias tires
- Scuff Guard sidewall
- Sits at the top of the Trailer Tires category ranking
- Deep tread for longer mileage life
Cons
- Rims not included
- Load range D is not right for the heaviest tow-only campers
Many small travel trailers and teardrops still ride on 14-inch wheels, and this is the radial upgrade for them. Steel belted radial construction at 8-ply load range D changes the ride quality and the wear pattern noticeably compared with the bias tires most of these trailers left the factory on.
At 2,040 lb per tire and 65 PSI cold, it handles trailers up to roughly 8,100 lb gross. For a sub-5,000 lb trailer on 14-inch rims, that is the correct capacity without overbuying.
Two things stand out in the owner feedback. First, this tire ranks at the top of Amazon’s Trailer Tires category, which tells you something about how many buyers land on it by default. Second, the recurring complaint is only one thing: rims are sold separately.
That is a good problem to have. A tire that fits the most common trailer rim widths and draws consistently strong owner feedback is exactly what you want in a part that is hard to diagnose when it goes wrong.
Who the Free Country ST205/75R14 suits
It suits small and midsize travel trailers, pop-up campers, and boat trailers still on 14-inch rims. If your trailer weighs under 5,000 lb, this capacity class is appropriate and the radial casing gives you a better ride than what it replaced.
It also suits anyone who wants to move off bias construction without changing wheels or spending on a larger tire.
Who should skip it
Skip it if your trailer is a heavy tow-only camper. Load range D means 8 plies and a 65 PSI ceiling, which leaves less margin for long highway runs with a heavy tongue weight.
Skip it if you need a full set of four in one purchase. This listing is built around pairs, so a full axle change means two orders and matching production dates by hand.
6. Transeagle ST235/80R16 Load Range G 14PR – Best for Heavy 16-Inch Trailers
Transeagle ST Radial All Steel Heavy Duty Premium Trailer Radial Tire-ST235/80R16 235/80/16 235/80-16 129/125M Load Range G LRG 14-Ply BSW Black Side Wall
ST235/80R16 radial
Load range G 14-ply
4079 lb per tire
110 PSI max cold
Pros
- Highest capacity in the group at 4079 lb per tire
- All-steel casing for heavy dump and landscape trailers
- Resists nails and wears very slowly in commercial use
- Some buyers report fresh date codes
Cons
- Taller profile can rub fender covers on some campers
- Heavier and costlier per tire than 14- and 15-inch options
- Rim not included
When a trailer needs more than the 80 PSI ceiling of a load range E tire, the next step up is load range G, and this is where that step starts. At 4,079 lb per tire and 110 PSI cold, it is built for the kind of trailer that would never be called a travel trailer in the first place.
Commercial users running 12,000 to 16,000 lb trailers report resistance to punctures and very slow wear. The all-steel casing is the reason, and it is a meaningful upgrade over the semi-steel and nylon-capped designs used on lighter trailer tires.
The 235/80R16 profile is tall, and that is the tradeoff. Overall diameter increases, which changes your speedometer reading and can bring the tire close to fender covers on campers with low clearance. Measure before you commit, especially if your trailer has plastic fender skirts.
The 50 lb tire weight also matters on light trailers. Four of these add meaningful unsprung weight, which can make a small trailer feel less responsive behind the hitch.
Who the Transeagle ST235/80R16 suits
It suits owners of heavy dump trailers, landscape and equipment trailers, and large travel trailers running 16-inch wheels. If your GVWR calculation leaves you wanting more than 2,830 lb per tire, this is the capacity class you need.
It also suits commercial operators who measure tire life in miles rather than seasons, since the all-steel casing wears slowly under heavy load.
Who should skip it
Skip it if your trailer is under about 6,000 lb. You would be carrying 200 extra pounds of tire and paying for capacity the trailer never asks for.
Skip it if your fender clearance is tight. The taller sidewall profile is the most common fitment complaint in the reviews, and clearance problems show up as rubbing on turns and during turns on the nose.
7. Transeagle ST225/75R15 Load Range F 12PR – Best 12-Ply Stability
Transeagle ST Radial Premium Trailer Radial Tire-ST225/75R15 225/75/15 225/75-15 121/117M Load Range F LRF 12-Ply BSW Black Side Wall
ST225/75R15 radial
Load range F 12-ply
3197 lb single
95 PSI max cold
Pros
- Load range F 12-ply gives strong capacity in a 15-inch size
- 86 percent five-star ratings across reviews
- Radial casing tracks and wears better than bias designs
Cons
- Lighter 7.14 mm tread depth than several rivals
- Rim not included
- Lower category placement than leading trailer tire listings
Load range F is the sweet spot most people never shop for. It sits between the E tires everyone recommends and the G tires meant for equipment trailers, and at 3,197 lb single and 95 PSI cold it gives you real thermal headroom without the weight of a 16-inch all-steel tire.
The 225/75R15 size is also the most widely used trailer size in the country, which means parts availability, rim choices, and fitment knowledge are all on your side. The radial casing improves tracking and tread wear versus bias designs in the same size.
Owners show a high level of satisfaction, with 86 percent five-star ratings. The narrower 7.14 mm tread depth is the one specification that gives us pause, since it wears faster than the 11/32 patterns on the load range G tires.
For a trailer that spends most of its life on pavement, that trade works fine. For a rig that sees regular gravel and forest service roads, tread depth is worth more than the extra load range.
Who the Transeagle ST225/75R15 Load Range F suits
It suits owners of 6,000 to 8,000 lb travel trailers who want more capacity headroom than a load range E tire gives without moving to 16-inch wheels. The 95 PSI cold limit is a meaningful stability gain over 80 PSI.
It also suits anyone already running 225/75R15 who wants to stay in the same size and upgrade the rating instead.
Who should skip it
Skip it if your routes are mostly gravel and dirt. The shallow tread depth is the wrong characteristic for loose surfaces, and the money is better spent on tread depth.
Skip it if you are buying on review volume alone. At 404 reviews it has the smallest sample of the group here, so treat the strong rating as encouraging rather than conclusive.
8. Roundrule ST Hikee ST215/75R14 8PR – Best for Spare Tire and Light Trailers
Roundrule ST Hikee ST215/75R14 All Season D (8 Ply) Semi-Steel Tire
ST215/75R14 semi-steel radial
Load range D 8-ply
2205 lb single
Load index 108/103
Pros
- Lowest cost per tire in the group while holding a 4.7 rating
- Semi-steel casing holds air well over storage periods
- Fits common 14-inch trailer and spare applications
- Can often be hand mounted without a tire machine
Cons
- Speed rating L at 75 mph is below most rivals
- Load range D capacity is modest for heavier tow-only campers
- Rim not included
This is the spare-tire tire. Trailers sit for months with a spare mounted or sitting in a well, and air retention over long storage periods is the feature that decides it. Owners consistently praise how well the semi-steel casing holds pressure between trips.
It also works as a serviceable road tire on a genuinely light trailer. At load index 108 single, that is 2,205 lb, enough for a small travel trailer or a boat trailer comfortably inside its range.
Two practical notes. The speed rating is L, certified to 75 mph, which is below the M and N ratings on most of the group. That is rarely limiting for trailer use, but it is a fact worth knowing before you set your speed policy.
The second is mounting. Owners report being able to mount this tire by hand without a tire machine, which is unusual for a radial and genuinely useful when a spare has to go on at a campground or on a shoulder.
Who the Roundrule ST Hikee suits
It suits owners who need one tire rather than an axle, whether that is a spare, a single replacement after a road hazard, or a matching tire for a trailer that spends half its life parked.
It suits budget-conscious buyers too. It carries the lowest per-tire cost in this group and still holds a 4.7 rating, which is a combination that is hard to argue with for a light-duty fitment.
Who should skip it
Skip it for a heavy tow-only camper. Load range D at 8 plies is a modest rating for a trailer above 5,000 lb, and there is not much margin above the 2,205 lb figure.
Skip it if you plan to run sustained highway speeds above 70 mph with a heavy load. The 75 mph rating leaves you no room, and heat is the enemy of trailer tire life.
9. GREMAX ST225/75R15 Load Range G 14PR – Heaviest Duty in the 15-Inch Size
GREMAX 4 HD All Steel Trailer Tires ST225/75R15 14PR Load Range G 123/119M
Set of 4 ST225/75R15 all steel
Load range G 14-ply
3420 lb per tire
110 PSI max cold
Pros
- Highest load rating available in the 225/75R15 size
- All-steel casing with 11/32 tread depth for heavy duty
- Set of 4 in one purchase
Cons
- Highest cost in the group for a set of four
- Rims not included
- Listing size metadata does not match the stated tire size
Sometimes the trailer will not fit a 16-inch wheel, and that is when a load range G tire in the 15-inch size earns its place. At 3,420 lb per tire and 110 PSI cold across a set of four, this covers more trailer weight than any other option in the 225/75R15 fitment.
The 11/32 tread depth and all-steel construction make it a genuine heavy-duty part rather than a passenger tire with an E rating bolted on. Owners running it on large heavy RVs report solid results.
The warning here is about the listing itself. Several spec fields on the page, including rim size and aspect ratio, do not match the stated ST225/75R15 size. Verify the actual sidewall markings before you buy, because the tire itself is not the problem, the metadata is.
The warranty is also short at one year from the tire distributor, which is not generous for a set of four heavy-duty tires. You are paying for capacity, not coverage.
Who the GREMAX ST225/75R15 Load Range G suits
It suits owners of large heavy RVs and trailers that must stay on 15-inch wheels but need more capacity than any load range E or F tire provides. That combination is rarer than it sounds, and when you need it there are few alternatives.
It also suits anyone who wants maximum load margin without the weight and clearance problems of a larger diameter 16-inch tire.
Who should skip it
Skip it if your trailer is under about 6,000 lb. The price of a set of four at this rating is only defensible when you genuinely need the capacity, and most travel trailers never do.
Skip it if you want strong warranty coverage. One year is thin for a premium-duty purchase, and the inconsistent listing metadata makes it harder to resolve a problem if one appears.
10. DEMETER ST205/75R15 8PR – Longest Warranty in the Lineup
DEMETER Set 4 Radial Trailer Tires 205/75R15,Heavy Duty ST 205/75R15, 8 Ply Load Range D All Season Traction
Set of 4 ST205/75R15 radial
Load range D 8-ply
2040 lb per tire
65 PSI max cold
Pros
- Only 2-year limited warranty in the group
- Nylon-reinforced casing and abrasion-resistant compound
- Five-rib symmetric tread for straight tracking
- Low rolling resistance helps towing fuel economy
Cons
- Load range D 8-ply rating is modest for heavy tow-only campers
- Shallow listed tread depth of 0.25 inches
- Rims not included
Coverage is the reason this one stands out. Two years of limited warranty is the longest in the lineup, and on a part that most owners will buy once and keep for years, that changes the effective cost of ownership more than the sticker figure does.
The build is aimed at longevity rather than outright capability. A nylon-reinforced casing and a compound chosen to resist cuts, chips, and abrasion describe a tire designed to be walked down gradually, and owners do report a quiet loaded ride.
The five-rib tread design forms a flat, symmetric footprint, which is the right approach for a trailer axle where straight tracking matters and tread rotation for even wear is simpler. Low rolling resistance helps fuel economy when you are towing, which is a real cost line on long trips.
The manufacturer also recommends inflating to the 65 PSI sidewall maximum for full load capacity. That is worth following, because these tires are specified for capacity at that pressure rather than for a lower everyday figure.
Who the DEMETER ST205/75R15 suits
It suits owners of light to midweight trailers under about 5,000 lb who want warranty backing and low rolling resistance more than maximum load capacity. The set of four format also makes an axle change straightforward.
It suits owners who tow long highway distances and count fuel cost as a line item. Lower rolling resistance in a trailer tire is a quiet saving that accumulates.
Who should skip it
Skip it for a heavy tow-only camper. Load range D at 8 plies is an entry rating, and the 2,040 lb per tire figure does not leave room for a trailer near the top of the range.
Skip it if your routes include a lot of gravel. The listed 0.25 inch tread depth is shallower than several rivals, and it is the first thing that runs out on loose surfaces.
11. Roundrule Xtra ST235/80R16 Load Range G – Best for Sway Control
Roundrule Xtra ST235/80R16 129/125M All Season G (14 Ply) All Steel Tire
ST235/80R16 all steel
Load range G 14-ply
4079 lb per tire
110 PSI max cold
Pros
- Load range G capacity at 4079 lb per tire
- Deep 11/32 tread depth for longer service life
- Owners report reduced trailer sway and smoother rolling
- Costs well below local tire shop pricing
Cons
- Heaviest tire in the group at 56 lb
- Taller profile can require fender clearance checks
- Rim not included
Sway is the complaint we hear most from trailer owners, and tire choice is part of the answer even when it is not the whole answer. Owners running 22 to 24 ft trailers loaded to 8,000 lb report dramatically reduced sway and smoother rolling on this tire compared with what they had before.
The mechanism is straightforward. A 14-ply all-steel casing at 110 PSI holds its shape under load instead of flexing side to side, and that lateral stiffness is what keeps the trailer tracking behind the hitch.
The 11/32 tread depth is deeper than most of the group and helps with the wear pattern that follows long highway days. Owners also repeat the value advantage against local tire shop pricing for equivalent load ratings, which is significant when you need four.
Weight is the catch. At 56 lb per tire this is the heaviest tire we analyzed, and four of them add real unsprung weight to a trailer axle. Light trailers feel it in ride quality.
Who the Roundrule Xtra ST235/80R16 suits
It suits owners of mid-to-large travel trailers on 16-inch wheels who tow at highway speed and have felt sway they want to solve at the tire level. The capacity and stiffness combination is aimed squarely at that problem.
It also suits owners running gravel and mixed surfaces who want deep tread and high load rating in the same tire, which is otherwise a hard combination to find.
Who should skip it
Skip it if your trailer is light. Four tires at 56 lb each will noticeably change how a small trailer rides and steers, and the capacity is wasted on a sub-5,000 lb rig.
Skip it if fender clearance is tight. The taller 235/80R16 profile needs a measurement check, which owners mention as the recurring fitment issue.
12. Goodyear Endurance ST215/75R14 – Best Major-Brand Warranty Backup
Goodyear Endurance All Season ST215/75R14 108N Trailer Tire
ST215/75R14 radial
Load range D 8-ply
Speed rating N
65 PSI max cold
Pros
- Only major-brand option in the group with a replacement limited warranty
- Steel-belted polyester casing built for heavy loads
- Durawall sidewall tech and Scuff Guard
- Enhanced inner liner reduces air loss while towing
Cons
- Highest cost per tire at only load range D 8-ply
- Tire only with no rim included
- Smallest review base of the products analyzed
The Endurance is the only major-brand trailer tire in this lineup, and that matters for one reason above the rest: a replacement limited warranty. When a tire fails under warranty you are dealing with a manufacturer and a dealer network rather than a marketplace listing.
The construction is genuinely good. Polyester reinforced with steel belts, an optimized tread depth and decoupling groove that lowers operating temperatures when properly inflated, and an enhanced inner liner that minimizes air loss while towing, which is a small thing that matters a lot on a trailer.
Durawall technology and Scuff Guard defend the sidewall against scuffs and punctures, which on a trailer is arguably more valuable than tread design. Trailers live beside kerbs, chocks, and gravel shoulders, and sidewall damage is the failure mode that ends a tire’s life early.
The honest drawback is cost. At load range D and 8 plies, you are paying a brand premium for the same capacity class as several lower-cost radial tires in this group.
Who the Goodyear Endurance suits
It suits owners who want a recognized manufacturer behind the warranty and who prefer buying from a dealer network when something goes wrong. For a first trailer where confidence matters more than the lowest per-tire cost, that is a reasonable position.
It also suits owners of 14-inch trailers under about 5,000 lb who want sidewall protection more than maximum capacity.
Who should skip it
Skip it if you are running a heavier trailer. Load range D at 8 plies does not serve a trailer above 5,000 lb, and paying more for less capacity is a hard trade to defend.
Skip it if review volume is your main confidence signal. At 130 reviews it has the smallest sample here, so the rating tells you less about long-term behavior than the numbers on the 2,900-review tire.
How to Choose Tires for Towing a Travel Trailer
Start with the trailer’s GVWR, which is stamped on a placard inside the door frame or on the frame rail. Divide that number by four to get the load each tire must carry, then add a 10 to 15 percent margin. That margin is not padding; it covers the gravel you climb, the heat you soak up, and the tire that ages faster than the other three.
Load range and ply rating decoded
Load range is the letter on the sidewall and it is the number that matters most. Load range C is typically 6-ply, D is 8-ply, E is 10-ply, F is 12-ply, and G is 14-ply. Ply is the older way of saying the same thing, and load index is a separate number, a code like 108 or 113 that maps to an exact pound rating.
Here is how the letters translate. Load range C runs about 50 PSI, D about 65 PSI, E about 80 PSI, F about 95 PSI, and G about 110 PSI as cold inflation maximums. Per-tire capacity climbs with each step, so the letter is a shortcut for both strength and pressure.
Two PAA questions come up constantly: is 8-ply or 10-ply better, and is load range D or E better. The honest answer is that E is better whenever your load math gets close to the D rating ceiling, and unnecessary when it does not. A 3,500 lb trailer on load range D has margin to spare, and a 6,000 lb trailer on load range D does not.
Calculating the load index your trailer needs
Three steps. First, find the GVWR on the trailer placard. Second, divide by four. Third, look up the load index on your candidate tire and confirm it exceeds that figure plus your margin. If your trailer is 7,000 lb, each tire carries 1,750 lb, and a 10-ply load range E tire rated around 2,400 to 2,800 lb clears it with room.
One more number worth knowing is GAWR, the gross axle weight rating. If your trailer has a single axle, GAWR and GVWR are usually close. If it has a tandem axle, the per-axle limit can bind first, and that is where load range upgrades pay off most.
ST versus LT tires
An ST tire is Special Trailer, built and tested to a stricter standard for trailer duty. An LT tire is Light Truck, designed to steer and handle on a pickup while carrying heavy load. On a trailer axle the LT tire is the wrong tool, because you are paying for cornering performance you will never use and accepting less casing strength where you actually need it.
That also answers the common confusion about tow-vehicle tires. Your truck or SUV needs LT or passenger-rated tires chosen for that vehicle’s tow rating. Your trailer needs ST tires sized to the trailer’s GVWR. Two separate decisions, two separate sets of tires.
Reading tire size notation
A size like ST225/75R15 reads as ST for special trailer, 225 for section width in millimeters, 75 for aspect ratio meaning the sidewall is 75 percent of the section width, R for radial, and 15 for rim diameter in inches. Bias tires use a D instead of R, which is the single clearest way to tell the two constructions apart.
If you want a deeper explanation of sidewall markings before you buy, our trailer tire guide walks through the full sidewall layout including the DOT code and treadwear rating.
Speed rating, tread depth, and what they mean
Speed ratings run from S through T, H, L, M, N, and beyond. Trailer tires cluster around L, M, and N, which is appropriate because trailer tires are rarely about speed, they are about holding a load. The rating that matters more is pressure, because a tire run underinflated at highway speed generates the heat that destroys it.
Tread depth is written in thirty-seconds of an inch. Eleven thirty-seconds is a heavy-duty pattern that will outlast most owners, nine is solid, and anything under eight is thin from the start. Below 2/32 is the point where a trailer tire is finished regardless of how it looks.
Brands worth considering and brands to avoid
Carlisle, Free Country, Goodyear, Transeagle, Roundrule, and DEMETER are the names that appear most often in owner feedback here, and Goodyear Endurance in particular comes up repeatedly as the tire owners buy a second and third time. Goodyear Endurance is also discussed at length in our truck tire towing guide for people who need the tow-vehicle side of the equation.
What to avoid is not really a brand list but a shopping rule. Be cautious with tires whose listings have no verifiable load range, no stated max pressure, and no DOT date information. Cheap unbranded imports and marketplace private labels frequently skip all three, and forum discussion of tread separation and sidewall bulges tends to cluster around exactly those descriptions.
Tire Age, DOT Date Codes, and When to Replace
Rubber ages whether or not it is being used. Sunlight, ozone, and heat break down the compound from the outside in, and a tire that looks perfect on a shelf can be past its useful life. This is the most overlooked safety item on any trailer, and it is a top question in owner forums.
Reading the date code takes four steps. Find the DOT code on the sidewall, which is a two to four digit number followed by four digits. The first two digits are the week of manufacture, so 24 means week 24. The last two digits are the year, so 26 means 2026. Anything older than a couple of weeks in the current year means leftover inventory.
The consensus rule among long-distance owners is simple: inspect closely at six years old and replace at ten years old regardless of tread depth. That rule exists because a tire’s failure mode with age is sudden rather than gradual. Dry rot shows up as fine cracking in the sidewall, and a tire with cracks is done, even if the tread blocks still look new.
Replace rather than repair when tread is below 2/32, when you find sidewall cracks or bulges, when the sidewall has been cut or scuffed through the belt package, or when a puncture sits in the shoulder or sidewall. A single proper repair in the tread center is fine. Anything else is a new tire.
Sway Control, Tire Pressure, and the Pre-Trip Checklist
Sway is the most common complaint from trailer owners, and tires are one controllable part of it. An underinflated or overloaded trailer tire flexes side to side under load, and that flex is exactly what feeds a sway event that begins above 45 to 55 mph. Owners who run correct cold pressure report sway problems largely disappearing.
The rule is to inflate to the maximum cold pressure printed on the sidewall when the trailer is loaded, and check all four tires plus the spare on the same morning before departure. Cold means the tire has not been driven more than a mile or parked in the sun for hours. A warm tire reads several PSI high, and adding to a hot reading is how people overinflate.
On the tow vehicle, add pressure in the rear to the load-carrying recommendation in the door jamb placard while towing rather than going straight to the maximum sidewall PSI. Overinflating loaded tires reduces the contact patch and hurts wet braking.
A quick pre-trip checklist: check cold pressure on all four trailer tires and the spare; inspect every sidewall for cuts, bulges, and cracking; confirm tread depth reads above 4/32; check that all four tires match in size and load range; verify lug nuts and wheel bearing feel; and confirm the breakaway switch and safety chains are connected.
Trailer sway control hardware helps, but it works by damping motion that tire choice can reduce in the first place. Owners who added proper tires still fighting sway often find the remaining cause is tire pressure on the tow vehicle or hitch weight distribution. For towing hardware, our guides to towing mirrors and brake pads for towing cover the rest of the system.
Frequently Asked Questions
What kind of tires do I need for my travel trailer?
You need ST (Special Trailer) radial tires sized to the trailer’s GVWR divided by four, with a 10 to 15 percent margin. Most trailers under 5,000 lb run load range D at 65 PSI, and anything heavier wants load range E at 80 PSI. Your tow vehicle needs a separate set of LT or passenger-rated tires chosen for that vehicle’s tow rating.
What ply tire is best for towing?
For most travel trailers above 5,000 lb, 10-ply load range E at 80 PSI cold is the community consensus and the right default. Eight-ply load range D at 65 PSI is plenty for trailers under about 5,000 lb. Going higher to load range F or G only makes sense when your load math leaves you short.
What are the highest rated travel trailer tires?
Among the tires we analyzed, the Carlisle Radial Trail HD ST225/75R15 leads with a 4.7 rating across 2,958 reviews and the deepest review base in the group. For pure load capacity, the Transeagle ST235/80R16 and Roundrule Xtra ST235/80R16 both carry 4,079 lb per tire at load range G. The Goodyear Endurance is the pick for warranty backing.
Are 10 year old RV tires safe?
No. The consensus replacement rule is to inspect closely at six years old and replace at ten years regardless of tread depth, because age-related failure is sudden rather than gradual. Look for fine sidewall cracking, bulges, or ozone crazing. If a tire is ten years old, it is due regardless of how the tread looks.
How do I read a trailer tire date code?
Find the DOT code on the sidewall. The last four digits are the manufacturing date, with the first two digits meaning the week of manufacture and the last two digits the year. So a code ending in 2426 means week 24 of 2026. Anything older than a few weeks back means leftover inventory and an already-aged tire.
What tire pressure should I run on trailer tires when towing?
Inflate to the maximum cold pressure printed on the sidewall when the trailer is loaded, which is 65 PSI for load range D and 80 PSI for load range E. Check all four tires and the spare on the same cold morning before departure, since a warm tire reads several PSI high and inflating from a hot reading causes overinflation.
The Best Tires for Towing Travel Trailers in 2026
Under 4,000 lb, load range D at 65 PSI serves you well, and the Free Country ST205/75R14 is the pick for 14-inch rims. Between 4,000 and 6,000 lb, move up to load range E at 80 PSI, where the Free Country Grand Ride set of four is the strongest all-around choice. Between 6,000 and 8,000 lb, the Transeagle ST225/75R15 load range F gives you the pressure headroom that long highway runs demand.
Above 8,000 lb, you are into load range G territory, and the Transeagle ST235/80R16 or Roundrule Xtra in that size carries the capacity. If your main complaint is sway, heavier load range on stiffer casings is the tire-side fix, paired with correct cold pressure every single morning. Whichever you land on, verify the load index against GVWR divided by four, check the DOT code before mounting, and replace at ten years old no matter what the tread looks like. That discipline matters more than any brand name on the sidewall.
