Patent ID: 7131476

Claim:
A pneumatic tire having an equator located in a central radial plane axially inward of an outer side of the tire when the tire is mounted on a vehicle, wherein: a tread portion of the tire comprises a rubber portion incorporating short fibers, said rubber portion forming the tread surface; in a region of the tread portion between an outer grounding end thereof and the tire equator, the short fibers are oriented radially outward and inclined axially outward of the tire; the short fibers at the outer grounding end are axially inclined at an angle α 1 with respect to the radial direction of the tire, and the short fibers in the tire equator are axially inclined at an angle α 2 of 10 to 35° with respect to the radial direction of the tire; angle α 1 is greater than angle α 2 ; and in an inner grounding end, the short fibers are axially inclined at an angle α 3 of 0 to 15°with respect to the radial direction of the tire, and α 3 is smaller than the angle α 2 .
