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