ABSTRACT:
A pneumatic tire is mounted onto a rim with maximum loading, and with an air pressure corresponding to maximum loading, such that the ground contact shape has a gradually decreasing circumferential direction length from the tire width direction center to the portion corresponding towards the tire width direction outermost circumferential groove, followed by the ground contact shape having a gradually increasing circumferential direction length towards the tire width direction outside. In the ground contact shape, the relationships 0.02≦(A−B)/L≦0.1, and 0.02≦(C−B)/L≦0.1 are satisfied, in which A is the maximum length in the circumferential direction of the tire width direction outermost rib, L is the circumferential direction length of the tire width direction center, and B and C are distances in a tire circumferential direction which depend on the width of the tire width direction outermost rib and the width of the second rib from the outside in the tire width direction.
