    摘要： A pneumatic tire has a tread portion, a pair of axially spaced bead areas and a pair of sidewalls. A body ply carcass extends axially between the bead areas and contains three body ply layers which turn-up about the bead areas from inside to outside. Two of the body ply layers are of equal axial lengths with the third body ply layer being considerably less or greater than the other two layers. The highest turn-up end of at least one of the body ply layers has a height of between 42% and 55% of the tire section height.
