This code is found on the sidewall of your car's tires. It's usually molded onto the tire by the manufacturer. Also on the tire, manufacturers list a safety warning on your tire, which says how underinflating, overinflating, or overloading your car tires can cause serious damage. Radial tires are the traditional tires found on most cars. These tires have cords running across the tire from the points at which the tire touches the rim of the wheel.
Radial tires rely on steel belts for strength.
Belts are wound from steel filaments and run inside the circumference of the tire. Radial tires are generally used for vehicles not hauling heavy loads because they provide a lighter tire with less side support but with a high amount of durability for driving long distances. Diagonal tires have two or more body piles, and they cross at a 35-degree angle to the center of the tread. These tires can offer better traction for vehicles traveling long distances. Belted bias tires are similar to diagonal tires, except they have at least two belts under the tread.
