The basic structure of tyre consists of the following components :

1. ) Tread :- It is the part which comes into contact with the road surface. The tread is made from a mixture of many different kinds of natural and synthetic rubbers. 

It protects the body and provides high grip, longer life, maneuverability and durability to the tyre. 

2.)  Steel belts :- In steel belted radial tyres, belts made from steel are used to reinforce the area under the tread. 

These belts provide puncture resistance and help the tyre stay flat so that it makes the best contact with the road. 

3) Bead wires :- The bead is a loop of high strength steel cable coated with rubber. 

It gives the tyre the strength it needs to stay seated on the wheel rim and to handle the forces applied by the tyre mounting machines when tyres are installed on rims. 

4) Body :- It sustains the inflation pressure and endures load and road sjo. The body is made up of several layers of different fabrics, called plies . 

The most commonly used ply fabric is polyester cord. 

5.) Slidewall :- It is the most flexible part of the tyre and provides the lateral stability to the tyre.
