Why selected: high ply count and complete tread overlay contribute to stability and longevity. Caution: ensure proper mounting on compatible rims and verify your trailer’s axle capacity to avoid overloading.

Buying Guide
- What load range do you need? Higher Load Range (D, E) supports heavier trailers and longer trips, reducing heat buildup.
- Radial vs bias ply: Radial tires generally offer better mileage and stability; bias ply can be cheaper for light-duty, occasional-use trailers.
- Rim compatibility: Ensure bolt pattern, center bore, and rim diameter match your trailer wheels.
- Tire size and weight: Match the tire size to your axle rating and the weight of your boat and trailer.
- All-season performance: Look for all-season compounds if you tow in varied weather; consider Scuff Guard features for rim protection.
