Buying Guide
What to consider when choosing 13-inch trailer tires
Determine the tire type first: bias ply vs radial. Radial tires generally offer longer life, better road stability, and superior shock absorption, while bias ply tires can be a cost-effective option for light towing.
Check load rating and PSI requirements. Match max load and inflation to your trailer’s gross vehicle weight rating (GVWR) and axle setup to avoid under- or over-loading.
Wheel compatibility matters. Confirm the rim width (commonly 13×4.5 inches), center bore size, and lug bolt pattern (usually 5 on 4.5 inches for these products). Ensure the DOT-approved assembly includes a secure valve stem and proper wheel fit.
Consider tread design and durability. Deep tread is designed for longevity; scuff guards on tires help protect rims. For saltwater or humid environments, corrosion-resistant finishes on white or galvanized wheels can be beneficial.
Warranty and roadside assistance add value. Look for longer warranties and included roadside support to reduce maintenance concerns on the road.
How to compare options quickly
- Radial vs Bias Ply: choose radial for stability and life; bias ply for budget.
- Load rating: ensure the tire’s max load aligns with your trailer’s needs.
- Wheel type and finish: white, galvanized, or spoke designs match your trailer’s style.
- Warranty and roadside: longer coverage helps during heavy-use seasons.
