CONSTITUTION:Inner and outer carcass plies 10, 11 are provided, while extending from a tread part 2 through a side wall part 3 to a bead core 5 of a bead part 4 and also being located radially inward and outward. The thermal contraction rate K1 of the carcass cord of the outer carcass ply 11 at 150 deg.C is set to 120-160% of the thermal contraction rate K2 of the carcass cord of the inner carcass ply 10 at 150 deg.C before vulcanizing molding.
