Abstract
A cord inclination angle of the outermost belt layer of a tire on the right side with respect to a tire running direction is arranged in such a manner as to be inclined leftwardly downward in the tire running direction while the cord inclination angle of the outermost belt layer of the left tire is arranged in such a manner as to be inclined rightwardly downward in the tire running direction. In addition, projecting bent portions of lug grooves on a tread pattern of a tire grounding surface are disposed outside from the center of a tread exploded width in the tire running direction.
Claims3
In right and let pneumatic tires that are fitted to a car on the opposite end of the same axis, characterized in that:
- (1) a cord inclination direction of the upper belt layer of the tire on the right side with respect to a tire forward running direction is arranged in such a manner as to be inclined leftwardly and rearwardly with respect to the tire forward running direction and a cord inclination direction of the upper belt layer of the tire on the left side with respect to the tire forward running direction is arranged in such a manner as to be inclined rightwardly and rearwardly with respect to the tire forward running direction;
- and
- (2) a tread pattern consisting of a plurality of parallel ring-like main grooves in a tire circumferential direction and parallel angled lug grooves connecting said main grooves to one another on a tire grounding surface, said lug grooves being angled to project rearwardly with respect to the tire forward rotating direction from the opposite sides of a main groove disposed outside of the center of the tread width in the tire running direction.
