Tire

A Rubber Tire is a device covering the circumference of a wheel. It is an essential part of most ground vehicles. The combination of air with rubber tire supports the vehicle and its contents.

Parts of a Rubber Tire

• The Bead: fits inside the rim of the wheel and is held in place by tire pressure.
• The Sidewall: protects the cord plies and has all the tire information printed on it.
• The Tread: provides strength and stability and is the interface that provides traction to the road surface.
• The Belt Plies and Body Plies: give the tire its stability and resistance to road damage.
• An inner liner: combats permeability (keeping the air in the tire).
• Sipes: are small slits in the tread that improve traction.

Functions of Rubber Tires

• Rubber Tire absorbs the shock of road roughness and can provide a smooth, safe ride.
• They protect the wheel from wear and tear.
• They provide a high-friction bond between the vehicle and the road to improve acceleration and handling.
• They also provide other functions such as traction for moving, stopping and steering as well as providing a cushion for the vehicle

Materials used for making Tire
Synthetic rubber is the material used for making tires. However, other materials like steel may be used later.

Maintenance of Tires
Proper tire inflation and maintenance is not only critical to the safe operation of any vehicle but will also improve fuel economy, extend tire life, provide better vehicle handling, help to prevent avoidable breakdowns and collisions, reduce exhaust emissions.

• To lengthen the life of a tire and increase mileage, it is necessary to align the wheels properly.
• While replacing tires, care should be taken to install with the same or higher speed rating as per the vehicle manufacturer's recommendation.
• Maintenance of proper air pressure is very critical. The difference of a few PSI can have a major impact on the handling and longevity of the tire.
• They should be checked regularly for cracks and bald spots.
