Abstract

A pneumatic tire includes a belt layer and a carcass layer. A rubber composition for belts, constituting the belt layer, contains, per 100 parts by mass of a diene rubber containing a natural rubber, from 0.3 to 1.5 parts by mass of cobalt borate neodecanoate and from 4.5 to 7.0 parts by mass of sulfur. The dynamic storage modulus at 20° C. of the rubber composition for belts is from 13 to 18 MPa, and a ratio of a 100% tensile stress of the rubber composition for belts to a 100% tensile stress of a rubber composition for carcasses, constituting the carcass layer is from 1.5 to 2.5.
