Buying Guide
What to consider when choosing B78-13 trailer tires for boats
- Load capacity: Most 13-inch, 6PR tires offer around 1360 lbs per tire at 50 PSI. Verify your trailer’s axle and tongue load to avoid overloading.
- Tread design: Deep tread extends wear life and traction on damp or uneven surfaces. Choose deep-tread options if you travel on gravel or rough roads.
- Wheel compatibility: Ensure the wheel is 13 inches, with 5-lug, 4.5″ bolt pattern and bore around 3.19 inches. Incorrect fitment leads to mounting issues.
- Set vs. single tires: Sets can simplify replacement, especially for utility or boat trailers. Consider whether you need two tires or four or more for the entire axle.
- Warranty and roadside support: Some packages include a 2-year warranty and roadside assistance, which helps during long trips.
- Installation readiness: Pre-mounted wheel assemblies save time. Confirm your hub size and stud pattern match before installation.
- Price vs. longevity: Deeper tread and premium tires may cost more but can deliver longer life and better performance on extended trips.
