Abstract
An improved pneumatic tire having a high cornering performance on a wet road as well as a high wandering performance and a wear resistivity is disclosed, which comprises a tread with a plurality of grooves which open to the axially outer edge or edges of the tread, the center line in a cross section of each of the grooves at least in the tread edge portion being axially inwardly inclined with respect to a vertical line perpendicular to the surface of the tread and the angle "H" between the center line and the vertical line being gradually increased as the position of the cross section is away from the equator plane of the tire.
