Tyre A tyre is a cushion provided with an automobile wheel. It consists of mainly the outer cover i.e the tyre and the tube inside. The tyre tube assembly is mounted over the wheel rim. It is the air inside the tube that carriers the entire load and provides the cusion. . The tyre performs the following functions 1 Supports the vehicle load 2 Provides cushion against shocks 3 Transmits driving and braking force to the road 4 Provides cornering power for smooth steering Tyre Properties Non skidding This is one of the most important tyre properties. The tread pattern on the tyre must be suitably designed to permit least skidding even on wet roads. Uniform wear To maintain the non skidding property, it is very essential that the wear of the tyre treat must be uniform. The ribbed tread pattern helps to achieve this. Load carrying capacity The tyre is subjected to alternating stresses during each revolution of the wheel. The tyre material and design must be able to ensure that the tyre sustains the stresses.
11 Cushioning The tyre should be able to absorb high frequency vibrations setup by the road surface and thus provide cushioning effect
