ST175/80R x 13C Radial Trailer Tire

Radial Tires have sidewalls that are more flexible than bias sidewall tires, so radials will give you a softer ride at the same PSI inflation compared to bias tires. Radial tire tread runs cooler because the tire has less rolling resistance, which increases the tire mileage life and improves vehicle fuel mileage slightly. Radial tires are ideal for extended highway use. While more costly than bias tires the longer life can make them a more economical choice over the life of the tire.
