Abstract

See full text

A pneumatic tire includes at least three circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions partitioned by the circumferential main grooves. The belt layer is formed by laminating a pair of cross belts having a belt angle, as an absolute value, of not less than 10° and not more than 45° and mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to a tire circumferential direction. Also, when viewed as a cross-section from the tire meridian direction, when the wear end surface of the circumferential main grooves is drawn, the distance Dcc on the tire equatorial plane from the circumferential reinforcing layer to the wear end surface and the distance De from the end portion of the circumferential reinforcing layer to the wear end surface have a relationship such that De/Dcc≤0.94.
