Abstract

This aims to provide a tire capable of making the reduction of a rolling resistance and the improvement in a gripping performance compatible while suppressing the occurrence of an offset wear. The tire (800) is constituted such that the distance (h2) of a second tread (842) is made larger than the distance (h1) of a first tread (841). In the state of a relatively small camber angle (of 0 or about 0 degrees), therefore, the ratio of the ground contact area of the first tread (841) of a low rolling resistance can be increased to spare the fuel consumption. In the state of a relatively large camber angle, on the contrary, the ratio of the ground contact area of the second tread (842) of a high gripping force can be increased to improve the gripping performance. By making the distance (h2) longer than the distance (h1), moreover, the offset action of a ground contact load on the second tread (842) can be suppressed, even if the camber angle is made relatively large, thereby to suppress the occurrence of the offset wear.
