Buying Guide
What to look for when choosing 235/85R16 12-ply trailer tires
- Load range and ply count: 12-ply tires with load ranges F or higher are designed for heavier trailers and higher ballast. Confirm that the rating matches your trailer’s axle capacity and load requirements.
- Construction type: full steel belts provide maximum resistance to punctures and even wear; semi-steel combines durability with ride comfort and cost efficiency. Choose based on route profile and maintenance goals.
- All-season traction: essential for variable weather. Look for tread patterns and belts optimized for wet, dry, and light snow conditions.
- Sidewall protection: features like Scuff Guards and nylon overlays reduce damage from curbs and debris. Evaluate if sidewall protection aligns with typical parking and storage conditions.
- Compatibility with trailer rims and speed: ensure the tire diameter and width fit your rim size and that the load index supports your typical speed range and highway miles.
- Warranty and replacement policy: verify coverage options and conditions, especially for fleets needing predictable maintenance.
Frequently Asked Questions
