Velocity WR078 ST225/75R15 E/10PR Tires. Manufacturer part number: WR0782257515E.
The Velocity WR078 trailer tire is a radial tire for travel trailers, pop-up campers, boat trailers and utility trailers used for hauling everything from racehorses to yard debris. This is a very versatile and long-lasting tire that is designed to make towing a trailer more enjoyable and more economical. The Velocity WR078 trailer tire has a ribbed tread pattern for traction. The rounded profile and extra rubber under the tread help to protect the tire from flats and gives it more stability, traction, and long-lasting wear. The tire's internal structure includes twin steel belts that stabilize the tread to increase traction and durability. This Velocity trailer tire is a special purpose trailer tire, that is not UTQG rated, nor is it for use on passenger car vehicles or light trucks. It must only be used on trailers.

Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic


Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.
