Patent ID: 6913053

Claim:
A pneumatic tire comprising: a tread portion; a pair of axially spaced bead areas each of which includes an annular bead ring and a bead filler; and a pair of side walls which include a body ply carcass having at least three ply layers consisting of an inner layer, an intermediate layer, and an outer layer extending circumferentially about the tire and axially between the bead areas to turn-up around the bead areas from inside to outside and terminate in turn-up end portions, said intermediate layer being different in axial length than said inner and outer layers which are substantially equal in axial length to each other, said said inner, intermediate and outer layers extending axially symmetrically about the bead areas, with the turn-up end portions of said inner and outer layers having substantially equal radial turn-up heights with respect to each other about the pair of bead areas such that the difference in radial height between said inner and outer turn-up end portions is no more than approximately {fraction (3/10)} of an inch, and the turn-up end portions of said intermediate layer having a different radial turn-up height than said turn-up end portions of said inner and outer layers such that the difference in radial height between said intermediate turn-up end portions and each of said inner and outer turn-up end portions is greater than approximately {fraction (3/10)} of an inch.
