Free Country Grand Ride Set 4 Trailer Tires

These 15-inch trailer tires come in a ST225/75R15 size with a robust 10-ply construction and load range E. The set includes a full cap ply nylon overlay that extends across the tread area, improving durability. A notable feature is the Scuff Guard ring on the tire wall, designed to protect the sidewall during parking and tight maneuvers. With quick replacement capability, this set aims to deliver reliable performance for long-distance travel and frequent trips.
The product uses a steel belt radial design that balances strength and flexibility. The 10-ply rating indicates a higher load handling capacity for heavier trailers, while the nylon cap ply enhances wear resistance. Potential buyers should verify fitment with their axle and rim specs to ensure proper compatibility.
Libra Trailer Parts Set of 4 Heavy Duty Tires

Libra Trailer Parts delivers a heavy-duty 4‑pack of ST205/75R15 tires, rated 10-ply with load range E and a stated 2400-lbs capacity. Like the Free Country set, these tires feature a full nylon cap ply overlay that spans the tread, offering increased durability over models with partial overlay. A Scuff Guard ring on the tire wall provides extra side protection against curb impact. The combination of increased ply count and protective features makes these tires well-suited for heavier trailers and demanding road conditions.
They emphasize reliability for long-haul trips and frequent loads, aligning with users who prioritize safety margins. Prospective buyers should confirm compatibility with their wheel dimensions and trailer weight, as well as whether the rims and hubs accommodate the 10-ply construction.
eCustomrim 2-Pack Trailer Tire And Rim Set

This 2-pack combines ST205/75D15 tires with 15-inch white spoke wheels, offering a complete wheel assembly ready for mounting. The tire is a load range C with 5-lug bolt configuration and a 27.2-inch overall diameter. The kit includes DOT-approved tires, a two-year warranty, and free roadside assistance, addressing both safety and convenience needs for trailer owners who want a turnkey setup. Weight ratings and speed compatibility should be checked against vehicle specifications to ensure a proper match.
Free Country Grand Ride Set 2 Trailer Tires

This 2-tire set features ST205/75R15, with an 8-ply load range D. The Full Nylon Cap Ply overlay spans the entire tread, which is a recurring feature in Free Country’s Grand Ride line. The Scuff Guard ring on the sidewall provides an additional layer of protection against curb and road hazards. This option is suitable for lighter trailer configurations or owners who prefer a smaller tire package for spares or certain axle configurations, while maintaining durability through the nylon cap ply feature.
As with other Free Country offerings, it is essential to verify compatibility with the trailer’s axle spacing and rim size to prevent fitment issues. The absence of a 10-ply rating does imply a lower maximum load compared to the 10-ply sets, so weight considerations should be reviewed before purchase.
WANDA Set 2 Free Country Trailer Tires

WANDA offers a 2-pack of ST205/75D15 bias tires branded as Free Country. These 6-ply, load range C tires provide deeper tread for longer life and a potentially smoother ride on varied surfaces. The bias construction is a traditional choice valued by some trailer owners for certain driving conditions and weight distributions. Rim compatibility and overall diameter should be checked to ensure a proper fit with your trailer’s wheels and suspension geometry.
When choosing among bias versus radial designs, consider ride stability, heat resistance, and climate conditions. Bias tires can perform differently under high-speed highway use compared with radial tires, so match your trailer use case to the tire type you select.
Durun Set of 2 Premium Trailer Tires

Durun offers a premium 2-pack of ST225/75R15 tires with 10-ply load range E. The package emphasizes a mix of bias-like construction with radial durability and a max load near 2830 pounds, along with a maximum 80 PSI rating. The tire uses premium rubber compounds and double steel belts with full nylon plies to provide robust performance and a long service life. Compatibility with your trailer’s rims and axle ratings should be confirmed, particularly with respect to load index and speed rating.
Durun 2-Pack ST205/75R15 With White Wheel

This 2-pack combines trailer tires ST205/75R15 with a 15″ white wheel, featuring a 5-on-4.5″ bolt pattern and a load range D. The package provides a ready-to-mount wheel tire configuration, suitable for those who want an all-in-one solution for quick install. The set’s tire is described as 8-ply with a load index around 2150–2160 pounds, offering a balance of durability and economy for mid-weight trailers. Check brake clearance and hub bore size before purchase.
MERXENG ST205/75D15 Trailer Tires

MERXENG provides ST205/75D15 tires with 6-ply construction and a load range C, designed for a variety of trailer types. The package notes a 5-lug on 4.5″ configuration and a 26″ overall diameter, suitable for many utility, travel, or light-duty trailers. These tires emphasize a balance between economy and reliability, with typical DOT approval and standard wear characteristics. Ensure correct rim width and bolt pattern compatibility with your trailer’s hub and brake setup.
Buying Guide: Key Purchase Considerations
When selecting 15 inch trailer tires, consider load capacity, ply rating, and the intended trailer use. Higher ply counts (like 8 or 10 ply) generally enable heavier loads but may affect ride quality and cost. Compare radial versus bias designs: radial tires typically offer longer life and better heat dissipation, while bias tires can perform well on certain trailer configurations and budgets.
Important safety features include a full nylon cap ply overlay, which adds tread stability and wear resistance, and a Scuff Guard or sidewall protector that helps defend against curb damage during parking and tight turns. Verify wheel and hub compatibility: rim diameter, bolt pattern, offset, center bore, and whether the wheel is compatible with your brake system, if equipped.
For mixed-use trailers (camper, cargo, horses, or utility), match the tire’s speed rating, heat resistance, and moisture tolerance to typical travel conditions. Always review the trailer’s gross axle weight rating (GAWR) and ensure the tire’s load index exceeds that rating by an adequate margin. If upgrading from a lower ply tire, confirm the upgrade does not necessitate new rims or a different inflation strategy.
Durability factors to weigh include tire construction (double belts and nylon plies), tread depth, and the presence of scuff guards. Depth and tread pattern influence traction on wet roads and gravel surfaces, while sidewall protection reduces risk of sidewall punctures and scuffs. Finally, confirm warranty coverage and roadside assistance options offered with the tire package.
