ABSTRACT:
A pneumatic tire comprising a tread which contacts a road surface and comprises a rubber composition which contains a rubber component composed of 70% by weight or more of a copolymer of a conjugated diene and a vinyl aromatic hydrocarbon and a remaining amount of another synthetic rubber and/or natural rubber, at least one reinforcing filler selected from a group consisting of carbon black and silica, and at least one type of vulcanization accelerator, such as bis(4-methylbenzothiazolyl-2)-disulfide, bis(5-methylbenzothiazolyl-2)-dis ulfide, mercapto-4-methylbenzothiazole, and mercapto-5-methylbenzothiazole, an amount of the reinforcing filler being 45 to 120 parts by weight and an amount of the vulcanization accelerator being 0.5 to 5.0 parts by weight per 100 parts by weight of the rubber component. Decrease in chipping resistance during tire use is suppressed, and both abrasion resistance and controllability on wet roads after use of the tire are improved.
