The Best 14 Ply Trailer Tires 235 80R16, Reviewed
Transeagle ST Radial All Steel Trailer Tire
What We Like
- 14-ply Load Range G rating
- All steel radial construction
- Highway all-season tread
- 50 lb weight aids handling
Trade-offs
- No treadlife warranty is provided.
- Only sold as a single tire, not a set.
The 14-ply Load Range G rating gives this tire serious towing confidence for heavy trailers like large flatbeds or enclosed car haulers. Its all-steel radial construction helps keep the sidewall stiff under load, which can reduce sway and improve stability at highway speeds. For someone who prioritizes raw capacity and durability over light weight, this Transeagle delivers exactly what you need without extra frills.
The trade-off comes down to weight: at 50 pounds each, these are lighter than the Hercules Strong Guard C-ST (57 lb) or the Roundrule Xtra (56 lb), but still heavier than the Evoluxx EST21 (53 lb). That extra heft helps with stability, but it also means more effort during mounting and a slight hit to unsprung weight. If you want the highest load rating in a familiar 235/80R16 size and don’t mind a modest weight penalty, this is the straightforward choice.

Evoluxx EST21 All Steel Trailer Tire
What We Like
- All steel radial construction for highway stability
- 14-ply rating for heavy loads
- Speed rated M (81 mph) for highway towing
Trade-offs
- At 53 lb, heavier than some all-steel options
- Black sidewall only, no white letter option
The trade-off is weight: at 53 pounds, it’s a few pounds heavier than the Transeagle ST Radial (50 pounds). That extra heft can add up on a tandem-axle trailer, potentially affecting fuel economy slightly. But if you prioritize all-steel durability and a high load ceiling for long highway trips, the Evoluxx delivers where it counts. It’s a purpose-built highway tire, not a mud-and-gravel all-rounder.

Roundrule Xtra All Steel Trailer Tire
What We Like
- All steel radial construction for durability
- 14-ply rating supports heavy loads
- Speed rated to 81 mph
Trade-offs
- At 56.0 lbs, heavier than some all-steel rivals
- Tire only, no rim or wheel included
The all-steel radial construction and 14-ply rating mean it’s built to handle sustained highway speeds and rough pavement without flexing or overheating. That makes it a strong fit for anyone who regularly tows near the weight limit and wants a tire that won’t give them second thoughts on a long trip.
The trade-off is heft. At 56 pounds per tire, this is noticeably heavier than the Transeagle, which comes in at 50 pounds. That extra weight adds up during installation and can affect unsprung load on the trailer, though it also suggests more steel in the carcass for puncture resistance. If you’re outfitting a lighter utility trailer or swap tires often, the Roundrule’s weight might feel like overkill, but for maximum load security, it’s worth the extra muscle.

Hercules Strong Guard C-ST Trailer Tire
What We Like
- All-steel radial construction for durability
- 14-ply rating supports heavy trailer loads
- Speed rated to 81 mph for highway use
Trade-offs
- At 57.0 lbs, heavier than some all-steel rivals
- Tire only, rim not included
The all-steel radial build and 14-ply rating give it the backbone for long highway hauls at speeds up to 81 mph, so you can keep pace with traffic confidently. It suits owners who prioritize strength and longevity over saving a few pounds, especially those towing large RVs or equipment trailers where every pound of capacity counts.
Weight is the main consideration here. At 57.0 pounds, this tire is noticeably heavier than the Transeagle, which comes in at 50.0 pounds. That extra heft means a tougher mounting job and a small fuel penalty. But for anyone who values maximum load security and all-steel toughness above all, the Hercules delivers the peace of mind that heavier construction brings. Just remember you’ll need to buy your own rims.

ZEEMAX Set of 4 All Steel Trailer Tires
What We Like
- All-steel construction for heavy loads
- 4080 lbs capacity per tire
- Set of four tires included
- Deep 0.38-inch tread for long life
Trade-offs
- 228 lb total weight makes handling difficult
- Rims not included in the set
Each tire in this set carries a maximum load of 4080 pounds, which means the four tires together can support a heavy trailer. The all-steel build and 14-ply rating add durability for demanding use, and the 0.38-inch tread depth is designed for long tread life. For someone who wants four matching tires in one purchase, this set covers the basics without extra frills.
Weight is the main factor here. At 228 pounds for the set, you will need help moving them around the garage or lifting them onto the trailer hub. Compared to the Carlisle CSL16, which is lighter per tire, the ZEEMAX set demands more muscle during installation. If you need a set of four all-steel tires and can manage the weight, this package fits that need.

REDYREPIR 4-DSRT81 14 Ply Trailer Tire 235 80R16
What We Like
- All-steel casing for stable towing
- Five-rib wet-grip tread pattern
- Grooves channel water for wet traction
- Tread design reduces rolling resistance
Trade-offs
- Rims not included with purchase
- Ships in two separate packages
- 9/32 tread depth is moderate for heavy wear
A 4,080-pound max single load per tire means this set can handle a substantial RV without breaking a sweat. The steel radial construction keeps the tire stable under heavy, shifting loads, which is exactly what you want when a crosswind hits your fifth-wheel or travel trailer. For RV owners who prioritize highway confidence and wet-road grip, the five-rib tread with those wave-shaped sipes is a thoughtful design that helps water clear out and keeps you pointed straight.
A moderate 9/32-inch tread depth is the main trade-off here. That shallower tread helps reduce rolling resistance, which allows the tire to run cooler and more efficiently on long hauls. If you tow seasonally and keep speeds reasonable, the REDYREPIR delivers a balanced mix of load capacity and wet traction that suits RV life well.

Suntek HD Trail Plus All Steel Tires
What We Like
- All steel radial construction
- Rated for highway use at 81 mph
- All-season tread for varied conditions
Trade-offs
- At 216 lbs for four, heavier than some alternatives
- Rims not included, tires only
- Speed limited to 81 mph for heavy loads
It’s built for the driver who wants a dependable all-season tire that won’t quit on a cross-country haul, combining solid weight capacity with a tread pattern designed to handle wet and dry pavement alike.
But if your priority is a tough, all-steel tire that can take a beating on the highway and still deliver all-season traction, this is a straightforward choice for the price-conscious builder.

Carlisle CSL16 Trailer Tire
What We Like
- Weighs just 41.2 pounds
- 14-ply load range G rating
- Highway all-season tread design
- Radial construction for stable towing
Trade-offs
- Lacks all-steel casing for heavy debris environments
- Heavier than comparable all-steel trailer tires
The Carlisle CSL16 weighs 41.2 pounds, which is lighter than every other single 14-ply trailer tire listed in this guide. That lower unsprung weight can reduce strain on your suspension and make the tire easier to handle when mounting or storing a spare. Despite the lighter build, it carries the same 14-ply load range G rating as the heavier options, so you still get the capacity needed for a utility trailer or small camper on highway trips.
If your trailer regularly rolls over construction sites, gravel roads, or rough terrain with sharp rocks, an all-steel option may be worth the extra pounds. For highway towing and paved-road camping trips, the CSL16’s lighter weight means easier mounting, less strain on your suspension, and simpler spare tire handling without giving up the 14-ply load range you need.
Mastertrack UN-All Steel Trailer Tires
What We Like
- Cool-running technology reduces heat buildup
- Multi-directional grooves for wet/dry grip
- Reinforced sidewalls for stable cornering
Trade-offs
- At 56 lbs per tire, handling two is a workout
- Speed limited to 87 mph, not for highway racing
Each tire carries up to 4,080 pounds when used singly. The cool-running design helps keep heat from building up on long summer trips, so you’re not just protected on paper, but also by engineering that extends the tire’s life. That makes this set a smart fit for anyone who values peace of mind over the lowest upfront cost, and who wants a tire that handles wet pavement and tight corners without drama.
Weight is the main factor here. At 56 pounds each, mounting a pair is a two-person job, and you’ll want a sturdy jack and some muscle. Compared to the lighter Carlisle CSL16 (41.2 lbs), these are noticeably heavier to lift and store. But that extra heft comes from a 14-ply all-steel construction that shrugs off road debris and resists wear better than lighter rivals. If you’re towing a boat, camper, or equipment trailer and you care about long-term durability and warranty protection, this Mastertrack delivers where it counts.

Mastertrack M-TRAC HDT Trailer Tires
What We Like
- 5-year warranty for peace of mind
- Cool-running technology reduces heat buildup
- Reinforced sidewalls for stable cornering
- Multi-directional grooves for wet/dry grip
Trade-offs
- Tire only, wheels not included
- At 57.6 lb, handling requires care
A pair of Mastertrack M-TRAC HDT Trailer Tires can carry up to 4080 pounds each when used singly, so they’re built for serious towing at highway speeds up to 75 mph. The cool-running technology cuts down on heat buildup, which helps the tires last longer and may even improve fuel economy by reducing rolling resistance. Reinforced sidewalls and multi-directional grooves give you responsive steering and reliable grip on wet or dry pavement. A 5-year warranty backs the set, adding peace of mind for frequent towers.
These tires ship without rims, so you’ll need to mount them on your own wheels. At 57.6 pounds each, the 14-ply construction gives them the strength to handle heavy loads. For comparison, the Carlisle CSL16 is lighter at 41.2 pounds, but the Mastertrack’s warranty and heat-reducing design make it a strong pick if you want long-term coverage and durability for heavy towing.

How We Evaluated 14 Ply Trailer Tires 235 80R16
Our evaluation is research-based, drawing from manufacturer technical data sheets, construction specifications, expert reviews of trailer tire performance, and common patterns reported by owners of heavy trailers. We did not perform physical testing; instead we analyzed the features that determine real-world towing safety and durability.
The four criteria that mattered most were ply rating and load capacity, construction type (all-steel radial versus bias), tire weight and its effect on handling and mounting, and speed rating for highway use. For this category, a 14-ply Load Range G rating is the standard for maximum capacity, but all-steel radial construction provides better heat dissipation and stability at highway speeds than bias-ply designs.
We also considered tread depth, wet-weather groove patterns, warranty terms, and whether tires are sold individually or in sets. A research-led evaluation cannot replicate years of highway wear, but it can identify which specifications and design choices consistently lead to better owner satisfaction for heavy towing applications.
What To Look For In 14 Ply Trailer Tires 235 80R16
Choosing the right 235 80R16 14-ply trailer tire means understanding how ply rating, construction, and weight affect your towing setup. Focus on load capacity, tire construction, and how the tire weight affects your trailer.
Ply Rating and Load Capacity
The 14-ply rating corresponds to Load Range G, which supports up to 4,080 pounds per tire depending on the model. This is the highest common ply rating for trailer tires and is necessary for heavy equipment trailers, large boat trailers, and fifth-wheel RVs. Always match the combined load capacity of all tires to your trailer’s gross vehicle weight rating (GVWR), leaving a safety margin for load shifts and highway heat buildup.
All-Steel Radial vs. Bias-Ply Construction
All-steel radial construction uses steel belts under the tread and steel sidewall plies, providing better heat dissipation, more stable highway handling, and longer tread life compared to bias-ply designs. Bias-ply tires have nylon or polyester cords crisscrossing at angles; they are more affordable but run hotter at highway speeds. For frequent highway towing at maximum load, all-steel radials are the safer choice.
Tire Weight and Handling
A single 235 80R16 14-ply all-steel tire typically weighs between 50 and 57 pounds. Four tires can add over 200 pounds of unsprung weight to your trailer, which affects acceleration, braking, and fuel economy. Lighter options like the Carlisle CSL16 are easier to mount but may not offer the same debris protection as all-steel casings.
- Verify your trailer’s GVWR and ensure four tires exceed it by a safe margin.
- Match all four tires to the same construction type (all-steel or bias) and tread pattern.
- Check the speed rating; M (81 mph) is standard for highway towing.
- Inspect tread depth; deeper tread extends replacement intervals.
- Confirm warranty terms; some brands offer multi-year road hazard coverage.
For heavy highway towing, an all-steel radial tire with a 14-ply rating is the safest foundation for your trailer.

Frequently Asked Questions
What does 14-ply rating mean on a trailer tire?
A 14-ply rating means the tire’s construction is equivalent to 14 layers of rubber-coated ply material, giving it a Load Range G classification. This supports the highest load capacities available for trailer tires, up to 4,080 pounds per tire at maximum inflation pressure.
Is all-steel construction better than bias-ply for trailer tires?
For highway towing with heavy loads, yes. All-steel radial tires run cooler at sustained highway speeds, provide more stable handling, and resist punctures better than bias-ply tires. Bias-ply tires are more affordable and work for lower-speed, lighter-duty applications, but they generate more heat at highway speeds.
How much weight can a 235 80R16 14-ply tire carry?
A 235 80R16 14-ply tire at Load Range G typically carries up to 4,080 pounds when inflated to 110 PSI. Always check the sidewall stamp for the exact maximum load rating for your specific tire model.
What speed rating do I need for highway towing?
Most 14-ply trailer tires are speed rated M, meaning they are certified for sustained use up to 81 mph. This is adequate for legal highway speeds in the US. Never exceed the tire’s speed rating, especially when towing at maximum load.
How often should I replace 14-ply trailer tires?
Replace 14-ply trailer tires every five to six years regardless of tread depth, or sooner if you see sidewall cracking, bulges, or uneven wear. Heat cycles from heavy towing can degrade the rubber compounds even when tread remains deep.
The Bottom Line
The Transeagle ST Radial All Steel Trailer Tire is our best overall pick for owners who need maximum load capacity and stable highway handling from a single tire. Its all-steel radial construction and 14-ply Load Range G rating make it the right choice for heavy equipment trailers, large boat trailers, and fifth-wheel RVs where safety margins matter most.
If you need a complete set of four tires delivered at once, the ZEEMAX Set of 4 offers the same all-steel construction with deep 0.38-inch tread for long replacement intervals. For RV owners who tow in wet conditions, the REDYREPIR 4-DSRT81 provides a five-rib wet-grip tread pattern that channels water effectively.
The single most important factor when buying 235 80R16 14-ply trailer tires is matching the combined load capacity to your trailer’s GVWR with a safety margin. Choose all-steel radial construction for highway use, and check tire weight if you mount and handle tires yourself.
