PURPOSE:To maintain grippability and also prevent road surface damage by constituting a tire in such a way that reinforcements composed of organic fiber, inorganic fiber, metallic powder, and ceramic powder are charged in rubber material and the compound member formed thereby is laid in tread rubber. CONSTITUTION:Reinforcements 6 composed of organic fiber made of nylon or the like, inorganic fiber made of styrene code or the like, metallic powder of iron or the like, and ceramic powder of silicon nitride or the like are charged in rubber material 7 to form a compound member C consisting of a flange section C2 of a large diameter and a shank section C1 of a small diameter, thus forming such shape as a stepped pin. The compound member C is laid in the blocks on both sides of a tread. By this constitution, grippability can be maintained and road surface damage can be prevented. |
