Note: The goals here are to balance load capacity with tread design, rim compatibility, and overall durability for common small-trailer use cases. If you’re replacing both tires and rims, consider a matching two-pack to ensure consistent wear and balance. For pure tire-only needs, prefer a bias-ply option with proven sidewall strength or a radial option if your trailer supports it and you need greater resistance to punctures on rough roads.

Buying Guide
What should you consider before buying ST175/80D13 tires on rims? Here are practical questions and answers to help you decide.
- What load rating do I need? Most ST175/80D13 tires for trailers are Load Range C (1360 lb) or 6PR versions. Choose based on the gross trailer weight plus cargo. If you regularly haul heavy loads, a higher ply or radial option may offer better durability.
- Should I pick bias ply or radial? Bias ply tires tend to offer robust sidewall stiffness and are common on smaller trailer tires. Radial tires can provide better tread life and stability on long highway runs but may require compatible rim and hub specs.
- Do I need a wheel and tire combo or just tires? If you want a quick install, a complete tire-and-wheel assembly is convenient. If you already have rims that match, tires-only options may save money.
- Is the center bore important? Yes. A proper center bore reduces hub offset and helps with proper seating on the axle. Confirm 3.19″ or your hub’s bore size before ordering.
- What about warranty and roadside assistance? Several sets include a two-year warranty and roadside help, which can be valuable for frequent travelers or long trips.
- Will these fit my trailer’s fenders and brake setup? Check overall diameter (24.4″) and rim width (4.5″ to 5″) to ensure clearance from fenders and any brake components.
