Quick Summary

A belted tire is a type of pneumatic tire that includes an additional reinforcing layer, known as a belt, beneath the tread. This belt is typically made of materials like fiberglass or steel. The primary purpose of this belt is to enhance the tire's durability and help prevent punctures.1

Belted tires are constructed with plies of cords that form the tire's carcass. These cords are set diagonally to the center line of the tread. The belt is then placed on top of these plies, directly under the tread surface. This design offers advantages such as longer tread life and improved fuel efficiency compared to conventional tires without belts. Belted tires also provide better resistance to blowouts and can reduce braking distances.12

In a bias-ply belted tire, another set of cords overlies the bias-laid ones. This extra set of cords, called a belt, is typically made of fibreglass. A radial-ply belted tire also has a belt running around the entire tire, but the cords are typically made of steel wire-mesh,…
