<p>A pneumatic tire with a rib pattern that is able to suppress uneven wear further than conventionally is provided. Uneven wear in the vicinity of the tread edge due to dragging and shoulder scrubbing wear can be suppressed more than conventionally by providing a pneumatic tire in which, under conditions that the pneumatic tire is mounted onto a rim with maximum loading, and with an air pressure corresponding to maximum loading, 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, and such that the following relationships are satisfied: 0.02‰ (A-B)/L‰ 0.1, and 0.02‰ (C-B)/L‰ 0.1. In these relationships: L is the circumferential direction length of the tire width direction center; A is the maximum length in the circumferential direction of the portion corresponding to the tire width direction outermost rib; B is the distance in the tire circumferential direction at a prescribed position of the portion corresponding to the tire width direction outermost rib, and C is the distance in the tire circumferential direction at a prescribed position of the portion corresponding to the second rib from the outside in the tire width direction.</p> |
