Patent ID: 8151847

Claim:
A pneumatic tire including a tread part contacting a road surface, at least two belt layers each formed of a plurality of parallel cords covered with rubber, and a pair of bead toes, the pneumatic tire characterized in that in the case where, in a cross section including the axis of rotation: the ends of a shortest belt layer, which is the shortest one, in length in a tire width direction, of the belt layers are set to be points B; points on a tire surface, between which the width of the tire is widest, are set to be points Q; a line segment connecting each point B and the corresponding one of the points Q is set to be a line segment BQ; and a line segment connecting the pair of points Q is set to be a line segment SW, an angle at which the line segment BQ and the line segment SW cross is 50° or smaller, wherein the angle at which the line segment BQ and the line segment SW cross is within a range of 20° to 40°, wherein in the case where, in the cross section: a line segment extending, parallel with the tire equator line, from the point B to the tread surface is set to be a line segment GB; and a line segment from the shortest belt layer to the tread surface on the tire equator line is set to be a line segment GA, the length of the line segment GB is 85% or less of the line segment GA, wherein, in the case where, in the cross section: a straight line extending parallel with the line segment SW through the bead toes is set to be a straight line M; and a line segment on the equator line extending, parallel with the tire equator line, from the tread surface to the straight line M is set to be a line segment SH, the length of the line segment extending, parallel with the tire equator line, from each point Q to the straight line M is 55% or less of the length of the line segment SH, and wherein, in the cross section, the outer contour line of the tire and the inner contour line of the tire in a region from the tire equator line to each point B are parallel with the line segment SW of within a range of ±10°.
