and the center of each radius of curvature R1, R2 lies is at the same position.
In addition, Japanese Unexamined Patent Application Publication No. 2011-230699A, for example, describes a pneumatic tire comprising at least one carcass and belt layer, a belt cover layer formed by spirally winding a reinforcing cord made of an organic fiber cord in the tire circumferential direction on the outer side of the belt layer in the tire radial direction, and a tread portion comprising a tread surface different in the groove surface area ratio on either side of the tire equatorial plane. The tread surface of such a pneumatic tire has a tread profile in which, when viewed in the tire median cross section, the outermost position in the tire radial direction is locatedbetter contact with the ground. However, when a camber is applied to a vehicle, durability at high speeds tends to decrease. This is because, in the case of a negative camber, ribs located on the inner side of the tire equator plane when the tire is mounted to a vehicle have a longer footprint length than ribs located on the outer side of the tire equatorial plane. Consequently, achieving both steering stability at high speeds and durability at high speeds when a camber is applied has been difficult.
The pneumatic tire described in Japanese Unexamined Patent Application Publication No. 2004-122904A is designed for enhanced durability. However, the pneumatic tire is for light trucks. Also, the pneumatic tire has a configuration in which, due to differences in the radius of
