Abstract:
A pneumatic tire comprising; a carcass comprised of at least one rubberized ply of a radial arrangement reinforcing a pair of sidewall portions and a tread portion between a pair of bead cores embedded in a pair of bead portions, a bead filler rubber taperingly extending outward from an outer peripheral surface of each bead core in the radial direction of the tire, a belt comprised of two or more cross cord layers reinforcing the tread portion on an outer periphery of the carcass and a pair of thick reinforcing strip rubbers having a crescent shape at a cross-section thereof and located at an inner face side of an innermost carcass ply to extend from a position near to the bead core through the sidewall portion to an end of the tread portion, wherein each of the bead filler rubber and the reinforcing strip rubber has a JIS A hardness at 25.degree. C. of not less than 70 degrees and a rebound resilience at 25.degree. C. of not less than 65% and a ratio of JIS A hardness of the reinforcing strip rubber Hs(R)) to JIS A hardness of the bead filler rubber (Hs(F)) is within a range of 0.9-1.15.
