PROBLEM TO BE SOLVED: To provide a pneumatic tire which uses rubber containing NBR hydride. SOLUTION: One or more parts of each rubber part member such as the carcass coat, belt coat, bead filler, side wall, rim cushion, chaffer, cap tread, and bead insulation that composes a pneumatic tire is formed of the rubber composition that blends 0-120 pt.wt. of methacrylic acid zinc and 0-60 pt.wt. of carbon black (however, the compound content of both shall be 10-100 pt.wt.) with 100 pt.wt. rubber containing 40 pt.wt. or more of an ethylene unsaturated nitrile-conjugated diene high saturated rubber in which the percentage content of conjugated diene unit is 30% or more. Furthermore, a layer of rubber adhesive which blends a predetermined diene rubber, acrylonitrile-butadiene copolymer rubber and a predetermined aromatic petroleum resin is adhered between each member and adjoining rubber as other members used for as the general purpose. |
