To provide a tire ensuring compatibility between a reduction of a rolling resistance and an improvement of grip performance.
The tire 100 has a constitution wherein a tire center line CL is located in a tread width W1 of a first tread 141, and therefore a fuel consumption is reduced by grounding the first tread 141 having small rolling resistance in such a state that a comparatively small (0 or its vicinity) camber angle is formed. In this case, an angle 2 is formed by a virtual line L1 and a virtual line L2, and the angle 1 is formed by the virtual line L1 and a virtual line L3, and therefore, a second tread 142 and an intermediate tread 143 are separated from a travel road surface. On the other hand, the grip performance is improved by grounding a second tread 142 having a high gripping force and the intermediate tread 143 in such a state that a comparatively large camber angle is formed.
