PURPOSE:To enable the running performance at the time of straight forward moving,and both controllability and stability at the time of cornering to be augmented by configurating a tire in such a way that the center section of the tire is made of high friction resistance rubber, the side of the tire is made of rubber of high gripping properties, and all of them are formed into an integral unit. CONSTITUTION:A tire 11 is composed of a carcass 12 and a tread 13. And beads 14 which are formed at the both end of the opening of the carcass 12, are coupled with a wheel rim 15, to which (15) a valve 17 is installed. In this configuration, the tread 13 is made of high friction resistance rubber at its center section 18, and is made of rubber of high gripping properies at its side section 19 allowing both of them to be bonded into an integral unit. In this case, styrenebutadiene rubber, for example, is recommended as high friction resistance rubber, and butadiene rubber, for example, is recommended as rubber of high gripping properties. This configuration enables running performance at the time of straight forward running,and both controllability and stability at the time of cornering to be augmented. |
