This four-tire set from GREMAX delivers full all-steel construction rated at 16-ply (Load Range H) with a maximum capacity of 4,190 pounds per tire and a 110 PSI rating. The all-steel radial design means both the belt package and the sidewall use steel reinforcement, which is critical for managing heat in heavy RV and trailer applications at highway speeds.

Verified buyers running these on large fifth-wheels report excellent durability with minimal tread wear over thousands of miles. The tires maintain stable air pressure with only a 1–2 PSI drop per year, and the steel sidewalls provide superior puncture resistance against road debris compared to fabric-sidewall alternatives. The set covers all four positions in one purchase, ensuring matched production dates.

The 16-ply rating makes these tires extremely stiff, requiring a heavy-duty tire machine for mounting. Some users note that bead seating on aluminum rims requires high inflation pressure (200 PSI in some cases), so confirmation of your rim’s pressure rating before purchase is essential.

This four-tire set from Libra Trailer Parts offers the same 16-ply Load Range H specifications as the single and pair options but at a multi-tire price point that reduces per-tire cost. Each tire carries a 4,190-pound load capacity at 110 PSI, with all-steel radial construction designed for heavy RV and trailer use.

Users towing 36-foot toy haulers weighing around 10,500 pounds report smooth ride characteristics with minimal sway after 3,000 miles. The tires exhibit even wear patterns and low operating temperatures at 70–75 mph, with internal pressure rising approximately 10 PSI during extended highway runs — a normal range for all-steel tires under load.

Several verified buyers noted that heavy balancing weights (6+ ounces per tire) were required on three of four tires, indicating the need for professional mounting and balancing. The same 110 PSI maximum requires rim compatibility verification, and the tire’s stiffness makes mounting a challenge without a commercial tire machine.

This pair of GREMAX all-steel radial tires is designed for buyers replacing two tires on a tandem or triple axle trailer. Each tire carries a 4,190-pound load capacity with a 16-ply rating (Load Range H) at 110 PSI. The all-steel construction extends beyond traditional steel-belted designs, providing reinforcement in the sidewall area that resists cuts and impacts from road debris.

Buyers using these on triple-axle boat trailers and 36-foot toy haulers report stable towing performance with no significant or abnormal wear after 8,000 miles. The tires hold air well, with a typical loss of only 1–2 PSI per year according to long-term user reports. The pair format works well for those who need to replace only one axle set or mix with an existing set of matched tires.

The heavy construction requires a tire shop with clamps rated for stiff sidewalls. Several users noted that balancing required more weight than standard tires, and the 110 PSI maximum may not be compatible with all aftermarket aluminum rims.

This two-tire set from ZEEMAX uses a 14-ply all-steel design (Load Range G) with a maximum capacity of 4,080 pounds per tire at 110 PSI. While not technically a 16-ply tire, the 14-ply rating still provides substantial load capacity for heavy RV applications at a lower price point than 16-ply equivalents. The 0.38-inch tread depth contributes to long tread life.

Users report these tires performing well on fifth-wheels and toy haulers across cross-country trips, with one account logging over 5,000 miles showing minimal wear. The tires handle wet road conditions without sliding issues, and the all-steel construction provides puncture resistance that exceeds most standard ST tires.

The 14-ply rating means these are extremely stiff, and verified buyers confirm bead seating requires 200 PSI on aluminum rims — a process that demands specialized equipment. The lower load index (129 vs 130 on 16-ply models) means a 110-pound reduction in capacity per tire, which matters for trailers operating near maximum GVWR.

The Roundrule Xtra All Steel tire stands out in the 16-ply category due to its 120 PSI maximum pressure rating — 10 PSI higher than most competitors. This higher pressure ceiling allows for increased load capacity at the same inflation level, providing an extra safety margin. Each tire carries 4,189 pounds at Load Range H with a 16-ply rating, backed by all-steel radial construction.

Verified owners on 36-foot fifth-wheels report improved fuel mileage compared to previous tire brands, with over 2,000 miles logged and no signs of bulging or heat damage. Users running these on dump trailers handling rough debris daily describe them as the most durable tires they have owned, with the heavy 56-pound weight per tire reflecting the robust all-steel build. The deep tread pattern provides good highway grip.

The maximum 120 PSI rating must be matched with rims capable of handling that pressure, which eliminates many standard aluminum wheels. Installation requires a shop with heavy-duty clamping, and the tire’s stiffness makes puncture repairs extremely difficult compared to more flexible tires.

GREMAX’s single-tire 16-ply option provides the same all-steel radial construction and 4,190-pound load capacity as the multi-packs, making it a practical choice for spare tire replacement or single-axle trailer applications. The tire is rated Load Range H at 110 PSI and features a full steel cord package in both the belt and sidewall sections.

Users running these on equipment trailers at 70–75 mph report good wear characteristics after 600 miles, noting that the tire rides smoothly when loaded but produces more bounce unloaded at high PSI. Compared to big-box store alternatives at a higher price point, buyers report fewer belt slip issues and better overall tire life.

A small number of reports mention outer tread belt separation after tight turns under heavy load. This appears related to the tire’s stiffness combined with tight turning radii at maximum weight — a scenario that stresses any all-steel tire. The single-tire format is ideal for spare duty but offers no cost savings over multi-packs for full replacements.

Transeagle’s entry into the 16-ply category uses all-steel radial construction with a 115 PSI maximum pressure and 4,189-pound load capacity. The tire is Load Range H rated and designed exclusively for trailer use. Its slightly lower maximum PSI (115 vs 120 on the Roundrule) still provides ample headroom for most heavy towing applications.

One verified owner reports achieving 60,000 miles per set with regular 5,000-mile rotation intervals — exceptional longevity for a trailer tire. Another user running a 40-foot fifth-wheel confirms no bulging under weight and no blowouts after multiple trips. The tire has earned follow-on purchases from commercial hotshot operators who replace them annually due to high mileage, indicating consistent reliability under sustained highway heat.

A single verified report of tread separation at 150 miles raises a quality control concern, though the same buyer notes that the manufacturer’s recommended alternative (Sailun) is not available in this price range. The return process for factory defects was described as a 5-month ordeal, so buyers should verify warranty terms before purchase.

Nebula’s Grand Trailer-N tire uses a 14-ply rating (Load Range G) with a 4,079-pound capacity at 110 PSI. While not reaching the 16-ply threshold, this tire still provides all-steel radial construction and a 30.8-inch diameter that matches 235/80R16 specifications. The 14-ply rating offers a good balance of load capacity and ride comfort for lighter heavy-duty applications.

Buyers using these on flatbed trailers hauling machinery report no failures and positive performance. The tire’s 57-pound weight reflects the all-steel build, and users describe them as “bad ass tires” that eliminate blowouts on toy haulers. The 14-ply construction is noticeably easier to mount than 16-ply alternatives, making them more accessible for DIY installers.

The 110-pound reduction in load capacity per tire (compared to 16-ply models) means a combined 440-pound lower total capacity across four tires. This reduction matters for trailers operating near their maximum GVWR. The 14-ply rating also means the tire has less steel reinforcement in the sidewall, which slightly increases puncture vulnerability compared to 16-ply all-steel designs.

The ROCKMAN ST235/80R16 is a 10-ply (Load Range E) tire with a load index of 124 and an 8 mm tread depth — significantly deeper than the 5.6 mm tread found on many economy competitors. While this tire does not match the 16-ply rating of the other options in this guide, its steel-belted radial construction and full nylon cap ply overlay provide respectable durability for lighter trailers at a substantially lower price point.

Users report these tires mounting easily with good bead sealing, and the date stamps confirm fresh stock rather than aged inventory. Buyers towing travel trailers at 60 mph estimate 1,000+ miles with stable ride characteristics and good tread wear. The M speed rating (up to 81 mph) exceeds the requirement for most towing applications.

The 10-ply construction means significantly less sidewall puncture resistance compared to 16-ply all-steel tires. This tire is best suited for lighter travel trailers and equipment loads under 8,000 pounds GVWR where the 16-ply rating would be overkill. For heavy fifth-wheels or commercial hotshotting, the lower ply rating represents a meaningful reduction in safety margin.
