CHOOSING YOUR TIRES
A tire is made up of many different components, all working together to help ensure you have a safe, smooth drive down the road. Listed below are the major components of the majority of tires.
- Liner. The liner is a calendared sheet of rubber that covers the inside of the tire. It is made from materials that allow the tire to hold the air pressure within the tire.
- Bead. The bead is a high tensile strength wire coated with rubber and wound to a specified inside diameter and number of turns. The bead provides the structure to hold the tire to the wheel.
- Chafer. The chafer is an extruded component that wraps around the bead area of the tire. It interfaces with the wheel to form a seal between the tire and wheel. The chafer is made from an abrasion resistant rubber that helps it hold up to the wear the wheel exerts on the tire.
- Ply. The ply is a calendared sheet of rubber coated fabric. All the other components in the tire are either directly or indirectly connected to the ply. The ply wraps around the bead on both sides of the tire and gives the tire its strength and the ability to flex without losing its shape.
- Sidewall. The sidewall is an extruded component that is the most visual part of the tire. The sidewall protects the ply from the environment, is abrasion resistant, and provides a substrate for the lettering and decorations to be molded into the tire. Sidewalls can have multiple compounds included in different zones such as a zone of white rubber for white sidewall tires.
- Belts and Overlay. The belts are a calendared sheet of rubber coated steel wire. The overlay is a calendared sheet of rubber coated fabric. The belts help provide rigidity, strength, and puncture resistance to the crown area of the tire. Many tires include overlay which is wrapped around the tire and covers the belts. The overlay helps improve the speed capabilities of high-performance tires.
- Tread. The tread is an extruded component. It can be made from a wide range of compounds based on the application of the tire. It provides a substrate for the tread pattern to be molded into the tire. The tread contacts the road and gives the tire grip to accelerate, stop, and corner. The tread also provides cushioning for a smooth ride.
