What is Tire?

     A Tire; which its raw material is rubber and where in the mixture prepared from supporting chemicals textile or steel chord threads are present in specified proportions and supported by steel wires at the heel region; is a composite structure and a pneumatic, dynamic system for carrying load.
The first step of wheel tire has been founded with the simple tire model for J.B. Dunlop’s suns three wheel bicycle by attaching a tent fabric with nails and where it obtained through blowing it with air on top of a wooden wheel with plastic solution injected.
Rubber has been used before for different purposes, but its use in the tire sector is realized with Goodyear’s cooking of rubber with sulfur (vulcanization) to shape it. Thereafter, a fast development has started in tire technology by Dunlop placing steel wires at heels and by developing inner tire and when 1920s arrived, cord fabric made of cotton were included in the main material of pneumatic wheel tire.
Today with the development of more resistant cord threads than cotton, instead of cord fabric and steel cords synthetic layer fabrics such as rayon, polyester and nylon are widely used. The classification and standardization of tires has started in the 1940s by the development of tire sizing system based on number-alphabet group which consisted of tire cut width and rim sizes.
