Question:
I have ST175/80D13 tires on my 5x8 utility trailer. I’m wanting to use it for long trips and faster speedsabout 70-80mph. I carry a kayak to tournaments. Can I put high speed tires on this trailer?

Helpful Expert Reply:
In the tire size that you have of ST175/80-13 we have the Contender ST175/80R13 Radial Trailer Tire # C17513C which will work well as it has a speed rating of up to 81 mph. This is a radial tire too which is a better construction than the bias ply that you currently have.
The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire run at a 90 degree angle to the direction of travel, or across the tire from wheel lip to wheel lip.
A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear.
A radial tire will normally run cooler than a bias ply tire, especially when the tire is under a load. A tire that runs cooler will last longer.
