Structure of tyre
Automobiles are normally equipped with inflatable tyres that are elastic and can buffer the impacts on the
traveling automobile and attenuate the vibrations caused thereby together with the suspensions so that the
automobile can travel stably; tyres and road surfaces have very good adhesions to each other so that the
automobile won't slip on the road and the towing and braking ability of the automobile can be improved.
