Abstract
In a pneumatic tire, a tread portion includes a main groove extending in a circumferential direction, and land portions defined by the main groove. A center region is a region where a center land portion included in the land portions is closest to a tire equatorial plane. Shoulder regions are each a region between a position corresponding to 85% of a width of the belt layer in a lateral direction and an end portion of the belt layer in the lateral direction, and intermediate regions are each a region between the center region and a corresponding one of the shoulder regions. A relationship among a tire average thickness Gc in the center region, a tire average thickness Gsh in the shoulder regions, and a tire average thickness Gm in the intermediate regions is within a range of 1.05≤(Gc/Gsh)≤1.35 and satisfies Gc≥Gm>Gsh.
