Free Country Premium Trailer Tires ST175/80R13
Best for trailer owners who want enhanced sidewall protection and a long-lasting tread. This set uses a full nylon cap ply overlay that extends across the tread area, offering improved durability compared with tires that only have nylon on the shoulders. The built-in Scuff Guard ring helps shield the tire wall and rim from damage. Best for frequent haulers and those who tow in mixed road conditions. Limitations: data indicates the premium design, but real-world longevity depends on road conditions and maintenance.

The assembly includes tire, wheel, and valve stem with a 13×4.5 inch rim and 5-lug pattern, designed for stable towing and consistent tire operation. It carries a 6-year warranty plus roadside assistance. Choose this if you value a tested, all-in-one package with easy compatibility across trailer models. Caution: ensure your trailer hub and wheel bore match the 3.19″ center bore requirement.

This assembly offers Load Range D with a 65 PSI rating and the same DOT-approved construction as the White variant, ensuring compatibility with a wide range of trailers. It includes a 6-year warranty and roadside assistance. Limitation: higher load range requires compatible wheel bore and lug pattern checks.
eCustomrim Trailer Tire Rim Assembly ST175/80D13 LRC
Best for standby use with bias-ply construction and Load Range C. This package uses a bias ply tire with a 24.4″ overall diameter and a 50 PSI rating, suitable for lighter-duty trailer applications or older trailers that require bias-ply construction. Caution: bias-ply tires generally wear differently from radial tires and may offer different performance characteristics on long highway hauls.
Free Country Grand Ride Set ST175/80R13 4 Tires
Best for owners who want a multi-tire package with a nylon cap overlay and Scuff Guard protection across four tires. The set is 8-ply rated with load range D and a high-speed rating up to 88 mph, designed specifically for trailer use. Rim not included. Consider this for complete trailer setups that prioritize long mileage and rim protection, but verify compatibility with existing rims before purchase.
Transeagle ST II ST175/80R13 8 Ply
Best for buyers seeking all-season performance with steel belt construction and high ply rating. The ST Radial II is described as a highway tire designed for trailers, featuring an all-season traction profile and an 8-ply D-rated setup. Use this when you need robust load support and stable towing across varied road conditions. Caution: ensure compatibility with your trailer’s axle load and rim specs.
Buying Guide: Key Purchase Considerations
- Load rating and ply: Match the tire’s Load Range and ply to your trailer’s gross axle weight rating and typical loads.
- Tread overlay and sidewall protection: Nylon overlays and Rim-Guard features can extend tread life and protect rims in rough conditions.
- Radial vs bias-ply: Radial tires generally offer longer life and better stability for highway towing; bias-ply tires may suit older trailers or specific applications.
- DOT-approved assemblies: If purchasing tire + rim kits, verify DOT approval and warranty terms for safety and coverage.
- Compatibility: Confirm rim size, bolt pattern (5 lug on 4.5″ center, as listed in several products), center bore, and overall diameter match your trailer hub.
- Warranty and roadside assistance: Some packages include long-term warranties and roadside support—consider value beyond price.
- Rim color and appearance: White vs black rims affect aesthetics but should not dictate safety; ensure coatings and finishes suit your trailer’s environment.
