PURPOSE:To provide excellent operational stability of a vehicle by functionally separating each front tire from each rear tire definitely. CONSTITUTION:A tire pair comprises a front tire F and a rear tire R each of which includes a radial carcass 1, a belt 2 formed by a non-extendable belt layer cord, and an auxiliary belt 4 formed by an organic fiber cord extended substantially in parallel to the equator of a tire and different in size from each other wherein the circumferential rigidity in a portion of the auxiliary belt 4 of the front tire F facing to the cross-direction central area of the belt 2 is made larger than that in the similar portion of the auxiliary belt 4 of the rear tire R. |
