Power consumption The automotive tyre should absorb some power which is due to friction between the tread rubber and road surface and also due to hysterics loss on account of the tyre being continuously fixed and released. This power comes from the engine and should be least. It is seen that the synthetic tyres consume more power while rolling than the ones made out of natural rubber. Tyre noise The tyre noise must be in the form of definite pattern, a sequel or aloud roar. In all these cases, it is desirable that the noise should be minimum. Balancing Balancing is very important consideration for tyres. The tyre being a rotating part of the automobile, it must be balanced statically as well as dynamically. The absence of balancing gives rise to peculiar oscillations called wheel tramp and wheel wobble.
