PURPOSE: To reduce a cleaning frequency for a molding die, and maintain the good appearance of a tire side section as well by constituting the outer layer of a pneumatic tire side wall with a rubber composite containing a specific amount of organic acid blended with a specific rubber.

CONSTITUTION: A pneumatic tire is constituted with a pair of right and left bead sections, a pair of right and left side wall sections continuous to the bead sections, and tread sections between each side wall section via shoulder sections. In the aforesaid pneumatic tire, at least the outer layer of the side wall sections is made of a rubber composite containing 100 weight parts of rubber comprising diene rubber, ethylene-propylene-diene copolymer rubber, butyl rubber halide or a mixture thereof blended with 0.2 to 5.0 weight parts of aromatic organic acid, alicyclic organic acid, or a mixture thereof. According to the aforesaid construction, a cleaning cycle for a molding die can be extended, and also the good appearance of a tire side section itself can be maintained.
