摘要： A tire for heavy load use includes a carcass ply made of steel cords including ply turn-up portions that are turned up around bead cores from inside to outside in a tire axial direction. Each ply turn-up portion includes a turn-up sub-portion that is first turned up around the bead core and that extends in an inclined manner towards the ply main portion at an angle θ, that is less than 90°, with respect to an outer surface of the bead core in the tire radial direction. The steel cords of the turn-up sub-portion include piercing steel cords that pass through the steel cords of the ply main portion. As a result, the durability of the bead portions is improved while achieving a light-weighted structure.

摘要： The invention relates to the heavy duty radial tire with a bead-wind structure. And carcass cords of the carcass extend while inclining to one side in the tire and the other-side inclined region that extends while inclining to the other side with a lowermost position of the bead core in the tire axial direction being substantially the center. Or, the reinforcing ply is similarly inclined as the carcass cords. With this arrangement, it is possible to improve engaging force of the carcass ply or the reinforcing ply to the bead cores so that shifts of the carcass ply in a blow-by direction can be effectively restricted. It is also an object to provide a heavy duty radial tire that is capable of restricting damages of the beads at the inner end positions A.

摘要： A heavy duty tire has a tread portion 2 which is divided into five inner, intermediate and outer rib-like land portions R1, R2, R2, R3 and R3. The inner rib-like land portion R1 is virtudally divided into half regions R1a and R1a on each side of a tire equator. The intermediate rib-like land portions R2 and R3 are virtually divided into tire equator-side half regions R2c and R3c, and into ground-contact edge-side half regions R2e and R3e. In a regular ground-contact state in which a normal load is applied, when total sums of ground-contact load applied to the half regions R1a, R2c, R2e, R3c and R3e are defined as P1a, P2c, P2e, P3c and P3e, P2c/P1a is set to 0.9 to 1.05, P2e/P2c is set to 0.75 to 1.0, P3c/P2e is set to 0.9 to 1.2, and P3e/P3c is set to 0.8 to 1.1.
