Abstract
A tread rubber G has a short-fiber-mixed rubber portion 10 forming a grounding surface. In a region Y1 between an outer grounding end Eo and a tire equator C located outside of a vehicle when a tire is mounted to the vehicle, the short fibers f are inclined and oriented at an angle α outward of the vehicle radially outward of the tire, and an angle α1 of the short fibers f in the outer grounding end Eo is greater than an angle α2 of the short fibers f in the tire equator C.
Claims6
A pneumatic tire wherein a tread portion comprises a short-fiber-mixed rubber portion made of short-fiber-mixed rubber produced by including short fibers in rubber, said short-fiber-mixed rubber portion forms the tread surface, in at least a region between an outer grounding end and a tire equator located outside of a vehicle when the tire is mounted to the vehicle, the short fibers are inclined and oriented at substantially an angle of α outward of the vehicle radially outward of the tire, and the angle α1 of the short fibers at the outer grounding end is greater than the angle α2 of the short fibers in the tire equator.
