PROBLEM TO BE SOLVED: To provide a pneumatic tire exhibiting good-looking black color to improve the appearance by increasing the blackness of the outer surface of the tire and keeping the appearance performance over a long time. SOLUTION: A rubber member 10 which has a glossiness of≥4 and a brightness L*of≤20 and is composed of a rubber composition obtained by compounding 10-60 pts.wt. of carbon black having a nitrogen-adsorption specific surface area (BET) of 120-460 m2/g based on 100 pts.wt. of a rubber component composed of 30-60 pts.wt. of EPDM and a halogenated butyl rubber in total and the remaining part of a diene rubber is placed on at least a part of the outer surface of the pneumatic tire 1. The use of the rubber member 10 as the displaying part 12 of the outer surface of a sidewall 3 is effective for improving the appearance. COPYRIGHT: (C)2008,JPO&INPIT
