A heavy-load trailer tire is a special-trailer (ST) radial built for towing that pairs all-steel sidewall and belt construction with a Load Range of E, F, G or H, which works out to 10 through 16 plies. That combination is what lets a single tire carry several thousand pounds without overheating or deforming. If you are searching for the best trailer tires for heavy loads, load range and per-tire pound capacity matter far more than tread pattern or brand badge.
We compared the specs, owner feedback and failure patterns across twelve heavy-load trailer tires to build this list. Each entry below carries a load index, a maximum cold pressure and a construction type, and we flag where the published numbers do not add up. Heat from underinflation or overloading, not the hitch, is what ends heavy towing.
Two rules frame everything that follows. First, match the tire to your trailer’s axle rating, not to the trailer’s total weight. Second, confirm your wheels are rated for the pressure before you step up in ply. We cover the arithmetic in the buying guide further down. If you also track heavy-duty gear for the garage and shop, our picks for industrial bakers racks and heavy-duty sewing machines follow the same capacity-first logic.

Best Trailer Tires for Heavy Loads Compared in 2026
The table below puts every tire’s load range, published capacity and pressure ceiling side by side. Use it to narrow your choices before you read the individual reviews.
1. Free Country Grand Ride ST225/75R15 10PR Set of 4
Free Country Grand Ride Set 4 Trailer Tires ST225/75R15 10 Ply Load Range E Steel Belted Radial w/Featured Scuff Guard
Load Range E 10-ply
2830 lb per tire
80 psi max
Speed rating N
Pros
- Set of four covers a full axle at once
- Full nylon cap ply spans the whole tread
- Scuff Guard ring resists sidewall scuffing
- Deep 9/32 in tread for long service
Cons
- Tires only
- rims sold separately
- 80 psi ceiling is lower than G and H rated tires
This set arrives as four tires and carries the largest owner review base we found: 2142 ratings averaging 4.6. Owners running loaded trailers report low wear after long highway stretches, which matches the 9/32 in tread depth listed for the model.
A full nylon cap ply runs across the entire tread width rather than stopping at the shoulders, and the Scuff Guard ring takes the hits that come from tight fender clearance and loading ramps.
Load Range E at 2830 lb per tire suits a mid-weight trailer. The 80 psi ceiling sits well below the 110 to 115 psi that G and H rated tires accept, so this is not the tire for a tandem axle sitting at its maximum rating.
Owners recommend swapping the valve stems while the tires are off the rim, a cheap fix that prevents slow leaks on a tire you cannot easily check later.
Will it hold up on a loaded tandem axle?
Only if each tire stays at or under 2830 lb and you run close to 80 psi cold. Owners of heavily loaded travel trailers report stable highway handling and no visible sidewall flex at that pressure.
Is this the right choice for your trailer?
It fits light-to-medium trailers on the very common 15-inch ST225/75R15 pattern, especially ones that see long highway runs at moderate load. Skip it if you need more than 80 psi, more than 2830 lb per tire, or a rating above N.
2. Transeagle ST235/80R16 Load Range G 14-Ply
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
Load Range G 14-ply all-steel
4079 lb per tire
110 psi max
Speed rating M
Pros
- Largest published capacity of any 14-ply tire here
- All-steel carcass resists bulging under load
- 110 psi ceiling supports stiffer sidewalls
- Reported fresh date codes on multi-tire orders
Cons
- Tire only
- rim not included
- Taller overall diameter can need fender clearance on some campers
This is the capacity leader here: 4079 lb per tire in Load Range G, with a 110 psi maximum cold pressure and an M speed rating. Owners running 12,000 to 16,000 lb dump and equipment trailers report strong puncture resistance and very little wear.
Several buyers specifically say this tire resolved blowout problems they had with 10-ply rubber on the same trailer. A stiffer all-steel sidewall deflects less, and less deflection means less heat generated inside the carcass on a loaded climb.
Fitment deserves attention. The 235/80R16 pattern has a taller overall diameter than a 225/75R16, and some campers need the fender cover trimmed before it fits cleanly. Measure the gap to the fender lip at loaded tongue weight first.
Note this is a single tire rather than a set, so plan on four. Buyers who order several report fresh date codes, which matters more than most people realize on a tire that may sit loaded for months.
Is 4079 lb per tire enough for a heavy trailer?
Divide your axle rating by two tires to get the real test. Four of these cover more than 16,000 lb, and 4079 lb per tire leaves generous margin on axles up to about 8000 lb.
What should you check before buying?
Confirm a 16-inch rim at 6.5 inches wide, a wheel rated for 110 psi, and loaded fender clearance. The only recurring complaint is that the tire arrives alone, so plan for separate mounting and check each DOT date code.
3. eCustomRim 8-14.5 Load Range H Tire and Rim Pair
eCustomrim 2-Pack Trailer Tire Rim Assembly 8-14.5 RV Mobile Home Load H
Load Range H 16-ply bias
3500 lb per tire
115 psi max
Mounted on 14.5x6 rim
Pros
- Arrives mounted so there is no mounting step
- D.O.T. approved metal valve stems
- Corrosion-resistant rim coating
- Two-year warranty from the brand
Cons
- Bias-ply design
- not a modern ST radial
- Heavier to handle than tire-only purchases
The 8-14.5 pattern is the classic trailer and mobile home size, and this option arrives already mounted on a matching 14.5×6 open-center rim, which removes the most tedious step in an axle rebuild.
Load Range H at 16 plies gives 3500 lb per tire with a 115 psi ceiling, which suits heavy mobile home axles and hay or equipment trailers. Buyers report exact fitment on 8-14.5 axles.
This is a bias-ply tire, so it handles differently on the highway than a radial, and one reviewer traced early flats to a loose valve stem. Check the stem torque yourself before the tire goes on the road.
The package is a pair, so a tandem axle means two orders. It weighs about 76 lb as a pair, so plan on a jack stand or a two-person lift.
Is a bias-ply tire right for highway towing?
For low-speed, farm and local work it is a durable, sensible choice. For long highway runs a radial rolls more easily and sheds heat better, though the 115 psi rating here buys real heat margin while loaded.
Why buy the mounted version?
Because the failure point in most DIY axle rebuilds is a bead or valve problem during mounting, and a factory-mounted pair removes that risk while matching the rim load rating to the tire from the start.
4. Free Country HD ST205/75R15 10PR Set of 2
Free Country HD Trailer Tires ST205/75R15 10PR LRE 111N w/Scuff Guard, Set2
Load Range E 10-ply
2400 lb per tire
80 psi max
Speed rating N at 88 mph
Pros
- Full nylon cap ply across the tread
- Scuff Guard sidewall ring
- Travel trailer owners report stable handling above 60 mph
- Virtually no wear after long highway trips
Cons
- Tires only
- rims not included
- 2400 lb is the lowest capacity in the 15-inch group here
The ST205/75R15 is the most common travel trailer size in the country, and this two-tire set covers the axle on most of them. With 1676 ratings averaging 4.6, it carries one of the largest owner review bases we found for a tire at this size.
Owners describe the same result repeatedly: confidence at highway speed and virtually no wear after thousands of miles, often as a direct replacement for cheap 4-ply tires that were flexing badly under load.
The full cap ply is the detail that separates this from a cheap tire of the same size. An overlay spanning the entire tread width stiffens the shoulder area, which is where heat concentrates when a sidewall deflects.
Capacity is the trade-off. At 2400 lb per tire and an 80 psi ceiling, this suits trailers in the 4000 to 5000 lb GVWR class rather than tandem axles at their rating. Check your axle figure before buying.
How much load can a travel trailer axle handle?
Most single axles under a 5000 lb GVWR fall well inside 2400 lb per tire, which is why this size works for so many campers. Tandem axles at their rating do not, and they need a G or H rated 16-inch tire instead.
Is 10-ply enough instead of 8-ply?
For most 13-foot and many larger travel trailers, yes. Owners report noticeably less flex and better stability once a 10-ply Load Range E tire runs near its ceiling. Beyond that, move to 14-ply Load Range G, and only if your wheels are rated for the pressure.
5. Free Country ST205/75R14 8PR Load Range D Set of 2
Free Country Set 2 Premium Trailer Tires ST205/75R14 8PR LR D w/Scuff Guard
Load Range D 8-ply
2040 lb per tire
65 psi max
14-inch rim at 5.5 inches
Pros
- Top 4.7 average across 846 ratings
- Ranks first in Amazon trailer tires
- Scuff Guard sidewall ring
- Established model with wide size availability
Cons
- Lowest load range here at D and only 2040 lb per tire
- 65 psi ceiling suits lighter trailers
- Rims not included
This listing carries the highest average rating in the roundup at 4.7 across 846 ratings, and it holds the number one rank in Amazon’s trailer tire category. The reasons are simple: fit, sidewall durability and steady value.
Be honest about what it is, though. Load Range D at 2040 lb per tire and a 65 psi ceiling make this a light-to-medium duty tire, not a heavy-load choice. It suits small utility trailers, boat trailers and lighter campers more than a tandem axle.
The Scuff Guard sidewall ring matches the heavier Free Country models, and it does its job on trailers with tight fender clearance or frequent loading dock use.
The 14-inch rim requirement is the practical constraint. If your trailer already runs 15-inch wheels, moving up to this tire means new rims, so compare it against the 15-inch options in this list first.
Can Load Range D handle heavy trailer loads?
Not when heavy means a tandem axle near its rating. D-rated tires sit at the bottom of the load range scale here, and the 65 psi ceiling leaves the least heat margin of anything in this roundup.
Why does it rate so highly?
Owners keep coming back for a second set, the model has broad size availability, and there is no reported failure pattern. Treat it as a quality baseline and choose a G or H rated tire if your axle rating is genuinely high.
6. Transeagle ST235/80R16 Load Range H 16-Ply
Transeagle ST ST235/80R16 130/126L All Season H (16 Ply) All Steel Tire
Load Range H 16-ply all-steel
4189 lb single, 3748 lb dual
115 psi max
Speed rating L
Pros
- Largest published capacity of any tire here
- 16-ply all-steel carcass resists bulging
- No visible sidewall deformation reported on 40-foot campers
- Worked on a 9000 lb trailer over steep grades
Cons
- 55 lb each
- heavy to mount one at a time
- Speed rating L caps use at 75 mph
At 4189 lb single and 3748 lb in a dual application, this is the highest published capacity in our list, and the 115 psi ceiling gives it the widest operating window too. Owners of heavily loaded campers and dump trailers point to the load margin as the reason they bought it.
The sidewall reports are worth repeating: buyers running 40-foot fifth-wheel campers see no visible deformation, and one owner used it on a 9000 lb trailer over steep grades without complaint.
The trade-offs are practical. At 55 lb per tire this is a two-person mount, and the L speed rating caps highway use at 75 mph.
A small number of owners report a tread separation within roughly the first thousand miles. It is an isolated pattern rather than a widespread one, but inspect new tires carefully during early service.
Do you really need Load Range H?
You need it when the arithmetic demands it. If your axle rating divided by two tires lands above about 3500 lb per tire, H is the load range that keeps you inside the rating with margin. Confirm your wheels are rated for 115 psi.
How much more can it carry than a G rated tire?
Single capacity goes from 4079 lb on the G rated 16-inch to 4189 lb here, a modest gain. The real difference is the 16-ply carcass and the wider pressure range, both of which buy heat margin on loaded climbs.
7. Libra Trailer Parts ST225/75R15 14PR Set of 4
Set 4 Heavy Duty All Steel Trailer Tires 225/75R15 14 Ply 124/121M 11150
Load Range G 14-ply all-steel
3420 lb per tire
11/32 in tread depth
Set of 4
Pros
- Step up to 14 plies without changing rim size
- All-steel build adds margin over 10-ply tires
- Deep 11/32 in tread suggests long service
- Set of four covers a full axle
Cons
- Listed maximum pressure is an implausible figure
- verify against the sidewall
- Rims not included
When owners want more capacity but their trailer is fixed on 15-inch wheels, this is the move. Load Range G at 14 plies in the ST225/75R15 size gives 3420 lb per tire without a rim change, and it arrives as a set of four.
Owners on large RV and equipment trailers chose it for the heavier all-steel build and the deeper 11/32 in tread, both of which suggest more service life than the 10-ply versions of the same size.
One thing to sort out before you inflate anything: the listing shows an implausible maximum pressure figure. Follow the number molded into the tire sidewall instead, which is the value that counts for heat behaviour.
Because this set runs at higher pressure than a 10-ply tire, verify your wheels are rated for it. Owners upgrading ply repeatedly make the same point: the rim becomes the weakest link, not the tire.
Is a 14-ply upgrade safe on 15-inch wheels?
It is, as long as the wheel is rated for both the pressure and the per-tire weight. Many 15-inch trailer wheels are stamped with a load rating and a pressure limit, and those numbers govern.
When is this upgrade worth it?
When you see sidewall flex and sway on a loaded 10-ply trailer, or when your axle rating per tire sits between 2830 and 3420 lb. Above that, go to a 16-inch G or H rated option, since going wider gives more headroom than stacking plies.
8. Roundrule ST Hikee ST235/80R16 Load Range E
Roundrule ST Hikee ST235/80R16 All Season E (10 Ply) Semi-Steel Tire
Load Range E 10-ply
3417 lb single, 2998 lb dual
Speed rating L at 75 mph
80 psi max
Pros
- Highest average rating among the 16-inch options
- Semi-steel build is lighter than all-steel equivalents
- Good entry capacity for a 10-ply tire
- All-season highway tread pattern
Cons
- Semi-steel construction is lighter-duty than G and H rated tires
- L speed rating caps highway use at 75 mph
The Hikee ST235/80R16 carries a 4.7 average across 356 ratings, putting it at the top of the 16-inch group here on owner satisfaction. Capacity is respectable for a 10-ply: 3417 lb single and 2998 lb in a dual application.
Buyers describe it as strong value for a 10-ply 16-inch ST radial on mid-weight trailers and campers. That is an honest description: it is not the tire for a tandem axle at its rating, but plenty of mid-weight trailers never go there.
The semi-steel build makes the carcass lighter than the all-steel 16-inch options, reducing unsprung weight on a trailer that carries the tire around all day. It also lists winter and year-round season ratings.
The trade-off is heat margin. An 80 psi ceiling on a semi-steel carcass leaves less room than the all-steel G rated tire, which is why owners step up in load range when they carry weight long distances.
Does a semi-steel tire handle heat as well as all-steel?
Not under the same pressure range. All-steel G and H rated tires accept 110 to 115 psi and carry more per tire, which spreads the load and reduces flex-driven heat. On lightly loaded routes under 75 mph the difference rarely shows.
When does this fit your trailer?
It fits a 16-inch trailer whose axle rating works out to about 3000 to 3400 lb per tire at 80 psi. Above that figure, budget for an all-steel G rated tire instead.
9. Transeagle ST II ST235/80R16 Load Range E
Transeagle ST II ST235/80R16 124/120L All Season E (10 Ply) Tire
Load Range E 10-ply
3527 lb single, 3086 lb dual
34 lb tire weight
80 psi max
Pros
- 3527 lb single capacity in a 10-ply package
- Lightest 16-inch tire we compared at 34 lb
- Reduces unsprung weight on lighter trailers
- Steel belted highway radial
Cons
- Load Range E is below G and H for heavy-load margin
- L speed rating limits use to 75 mph
The ST II is the lighter option among the 16-inch radials here, at 34 lb per tire, and that weight matters more than most buyers expect on a trailer that spends its life carrying its own weight.
Capacity is the bigger story: 3527 lb single and 3086 lb dual from a Load Range E 10-ply. Buyers treat it as a dependable 16-inch ST radial where satisfaction comes down to fit and the tire staying in its rating.
On a light trailer, four of these add up to 136 lb of unsprung mass, so dropping to a lighter set changes how a trailer tracks over rough pavement.
The 8/32 in tread depth is shallower than most competitors here, so expect this to be the tire that sets your replacement interval if you run it hard.
Does saving weight really matter on a trailer?
More than most people assume. Unsprung weight follows every bump and expansion joint, so a lighter set improves ride quality and reduces stress on bearings and suspension over time.
Is Load Range E enough capacity?
Enough for many single-axle trailers whose rating lands between 3000 and 3500 lb per tire, not enough for a tandem axle at its rating. Check the axle plate, divide by the tires on that axle, and compare against 3086 lb for a dual setup or 3527 lb for singles.
10. ZEEMAX 8-14.5 Load Range G 14-Ply Set of 2
Zeemax Heavy Duty TRUE Highway Trailer Tires 8-14.5 14 Ply Load Range G Speed Rating K 68mph- Set 2 …
8-14.5 bias-ply
Load Range G 14-ply
3100 lb per tire
115 psi max, speed rating K
Pros
- Built for true trailer duty rather than mobile home use
- 3100 lb per tire at Load Range G
- Works on older dual-axle trailers with mobile home hubs
- Two-tire set
Cons
- Speed rating K limits use to 68 mph
- Bias-ply construction is heavier than a radial
This tire is specified for true trailer use rather than mobile home duty, which matters if your trailer carries a load on the road rather than a static weight at a site. Load Range G at 14 plies gives 3100 lb per tire with a 115 psi ceiling.
Owners of older dual-axle trailers with mobile home hubs report it working where the tire choice is often awkward, citing the trailer-specific rating and the listing warranty.
The K speed rating caps this tire at 68 mph, below highway towing speed, and bias tires often arrive with flattened sidewalls that must be spread before mounting.
A minority of buyers also report transit damage or a size mismatch against the 8-14.5 marking. Inspect the tire on arrival and compare the molded size to your rim.
Bias-ply or radial for a heavy trailer?
Radials if you tow long distances at highway speed, because they roll more easily and shed heat better. Bias tires if your trailer runs at lower speeds or for stationary weight. The K rating here means this is not the choice for highway work above 68 mph.
Will it fit an older 8-14.5 trailer?
On most axles built for that pattern, yes. Measure rim width at 6 inches, confirm the hub style matches the open-center 14.5-inch wheel, and check the molded size rather than trusting the listing.
11. 4 WINDA ST225/75R15 10PR Load Range E Set of 4
4 WINDA Premium Trailer Tire ST225/75R15 Radial 10PR Load Range E Steel Belted
Load Range E 10-ply
2855 lb per tire
80 psi max
Speed rating L at 75 mph
Pros
- Set of four covers a complete axle
- Full nylon cap ply across the tread
- Scuff Guard sidewall ring
- Steel belted radial rated for trailer use only
Cons
- Speed rating L is lower than N-rated tires at this size
- Load Range E caps capacity near 2855 lb per tire
- Rims not included
This set covers a full axle with the same structural approach as the Free Country 15-inch tires: a full nylon cap ply across the entire tread and a Scuff Guard ring in the sidewall. Feedback centers on that construction rather than any reported failure pattern.
Capacity sits at 2855 lb per tire in Load Range E, and it carries a 4.6 average across 194 ratings, though the owner history behind it is thinner than the Free Country sets.
Is an L speed rating good enough for highway towing?
For most trailer work, yes. An L rating permits 75 mph, which covers typical posted limits where trailers are actually run. Choose an N rating at the same size if you want extra headroom.
Should you buy a full set or two at a time?
A set of four is the clean choice because all four tires share the same construction, wear pattern and date code. Mixing a fresh pair with a worn pair on one axle causes uneven wear. Rims are not included either way.
12. Grandforce GF704 ST8-14.5 Load Range G 14-Ply
Grandforce GF704 ST8-14.5 All Season G (14 Ply) Bias Mobile Home Tire
8-14.5 bias-ply
Load Range G 14-ply
115 psi max
22 lb tire weight
Pros
- Lowest entry cost among the tires we compared
- Light 22 lb construction reduces load on the hub
- Load Range G with a 115 psi ceiling at this cost
Cons
- Speed rating T is the lowest here and well under highway speeds
- Manufacturer does not publish load capacity
The GF704 is the lowest-cost entry point into a 14-ply Load Range G tire, and at 22 lb it is the lightest tire we compared. Owners on older mobile home and trailer axles buy it as a straightforward replacement for worn tires.
The 115 psi ceiling means this bias tire accepts the same pressure as much heavier all-steel radials, giving a loaded trailer genuine heat margin despite the low cost.
Now the limits. The T speed rating is the lowest in this roundup and sits well under highway towing speed, so this belongs on local, farm and site work. The manufacturer does not publish a load capacity figure, which makes it harder to size correctly.
One documented complaint is a size discrepancy where the tire measures closer to 7-14.5 than 8-14.5. Verify the molded marking before mounting, since a mislabeled size will not seat properly.
Is a Load Range G bias tire safe for heavy loads?
The load range itself is heavy-duty and the 115 psi rating supports it. The low speed rating restricts how fast you can run it, not how much it carries at low speed, which is fine for agricultural and site work.
What should you verify before buying?
Confirm the actual molded size, since the fitment discrepancy appears in owner reports. Check your hub and rim width against the 14.5×6 wheel the 8-14.5 pattern expects, and be ready to spread the tire before mounting.
How to Match Trailer Tires to Your GVWR in 2026
Load range letters tell you the plies, and the plies tell you the capacity
The letter after the size on a trailer tire is the load range, and it maps to a ply count: E is 10-ply, F is 12-ply, G is 14-ply and H is 16-ply. Each step up adds roughly 300 to 500 lb of per-tire capacity and a higher pressure ceiling, which is why load range matters more than width.
For heavy loads you want E at minimum, and G or H once your axle rating demands it. A Load Range C or D tire on a trailer carrying close to its rating is the most common cause of heat-related sidewall failure.
The arithmetic that decides your tire
Start with the axle rating, not the trailer rating. Divide the GAWR by the number of tires on that axle to get the pounds each tire must carry, then compare that with the single-tire load capacity on the sidewall.
For a tandem axle rated at 7000 lb with single tires, each tire carries 3500 lb, which puts you in Load Range G. Keep at least 10 percent margin above the calculated figure, so aim for roughly 3850 lb of capacity. Owners who hold that margin report fewer blowouts than those who run the calculation to the pound.
All-steel or nylon cap, and radial or bias
All-steel construction puts steel belts under the full tread width and gives the highest capacity and heat resistance, which is why G and H rated heavy-load tires are all-steel. A nylon cap ply, by contrast, adds a lighter overlay across the tread and is common on 8-ply and 10-ply tires. It stiffens the tire but does not replace steel belts at higher load ranges.
Radial versus bias comes down to where you tow. Radials roll more easily, dissipate heat better and suit long-distance highway work. Bias tires are heavier and less efficient at speed, but durable, inexpensive and fine for low-speed or stationary use. Do not mix radial and bias on the same trailer.
Pressure, age and replacement triggers
Check cold pressure on a regular schedule, not a yearly one, and measure the tire and wheel as a pair. Many owners run near the top of the max cold range when towing loaded on the highway, but never above the limit molded on the tire or stamped on the wheel.
Replace trailer tires at 2/32 in tread depth, which is barely visible on an ST tire, or at 5 to 7 years old regardless of tread. The final four digits of the DOT code give the week and year of manufacture, and a tire that sits unused and exposed develops dry rot long before its tread wears out.
Frequently Asked Questions
Who makes the best heavy duty trailer tire?
For the 15-inch pattern that fits most trailers, the Free Country Grand Ride ST225/75R15 set earns our top ranking for its 4.6 rating across 2142 reviews and a full cap ply plus Scuff Guard ring. For the highest capacity per tire, the Transeagle ST235/80R16 in Load Range G carries 4079 lb, and the Load Range H version of that size reaches 4189 lb.
What is the best tire for heavy loads?
A Load Range G or H all-steel radial is the best answer for heavy loads. In this roundup that means the Transeagle ST235/80R16 at 4079 lb or 4189 lb per tire, with a 110 to 115 psi maximum cold pressure. These accept more pressure and spread the load across a stiffer carcass than 10-ply tires, which cuts the flex that generates heat.
Is 8 ply or 10 ply better for trailer tires?
For most trailers, 10-ply Load Range E is the better choice. An 8-ply Load Range D tire carries about 2040 lb per tire at a 65 psi ceiling, while a 10-ply Load Range E tire carries roughly 2400 to 2855 lb per tire and runs up to 80 psi. Step up again to 14-ply Load Range G once your axle rating needs more than 3400 lb per tire.
Which is better, a load range C or D trailer tire?
A load range D tire, and the gap is modest. A C-rated tire carries about 1800 to 2000 lb per tire, while a D-rated 8-ply tire carries roughly 2040 lb. For heavy loads, neither is enough: move to E at 10 plies, G at 14 plies, or H at 16 plies depending on what your axle rating divides out to per tire.
What are the worst trailer tire brands to avoid?
Rather than naming brands, judge the specific tire. Red flags include a listing with no published load capacity, a speed rating at or below K for highway use, a molded size that does not match the listing, and a max pressure figure that looks wrong on its face. All four appear in owner reviews of otherwise acceptable tires in this roundup, so check the sidewall rather than trusting the listing.
Our Recommendation for Heavy-Load Trailers in 2026
The Free Country Grand Ride ST225/75R15 set is our pick for the best trailer tires for heavy loads on a typical trailer, because it pairs a full cap ply and Scuff Guard with the largest owner review base we found. If your axle rating needs more than 3400 lb per tire, the Transeagle Load Range G and H 16-inch radials carry 4079 lb and 4189 lb and accept 110 to 115 psi.
Check the axle plate, divide by tires on the axle, and leave yourself a 10 percent margin. Then confirm your wheels are rated for the pressure you plan to run, and inspect the sidewalls for the load index and DOT date code before anything goes on the road.
