Abstract
A pneumatic tire is provided with a main groove extending along a tire circumferential direction in a tread. A side wall of a land portion facing the main groove extends so as to be inclined with respect to a tire circumferential direction between a pair of corner portions. The corner portion positioned in an inner side in a width direction of the main groove is set to an inner corner portion and the corner portion positioned in an outer side is set to an outer corner portion. In the inner corner portion, the side wall is formed by a stepped surface expanding to the outer side in the width direction toward a groove bottom and an expansion to the outer side in the width direction in the stepped surface is made smaller from the inner corner portion toward the outer corner portion.
