Claim:
A pneumatic tire comprising: a toroidal carcass extending from a tread portion to each of bead cores in bead portions through sidewall portions, a belt layer disposed radially outward of the carcass in the tread portion, and a cushion rubber having an approximately triangular cross section and disposed between the carcass and each of axial edge portions of the belt layer, wherein the cushion rubber is made from a strip laminated body formed by spirally winding a first ribbon-like unvulcanized rubber strip and a second ribbon-like unvulcanized rubber strip in the circumferential direction of the tire, the second ribbon-like unvulcanized rubber strip having a different composition from that of the first rubber strip, the cushion rubber includes a main body made from the first rubber strip and an inner layer portion made from the second rubber strip disposed radially inward of the main body and being contiguous to the carcass, and the inner layer portion is made of a rubber having a thickness of 0.2 to 3.0 mm, a complex elastic modulus E*2 of 2.5 to 9.0 MPa which is larger than the complex elastic modulus E*1 of the main body, and a sulfur content of at least 1.0 phr.
