Pneumatic Tire

摘要

The pneumatic tire includes a carcass layer, a belt layer disposed outward of the carcass layer in the tire radial direction, and a tread rubber disposed outward of the belt layer in the tire radial direction. Moreover, the belt layer is formed by laminating a pair of cross belts having a belt angle with an absolute value from 10° to 45° both inclusive and mutually opposite signs, and the circumferential reinforcing layer having a belt angle within a range of ±5° relative to the tire circumferential direction. Moreover, the distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10≦Gsh/Gcc.
