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： [Object] To provide a pneumatic tire 82 which is excellent in durability.[Solution] A tire 2 includes a tread 4, wings 6, sidewalls 8, clinch portions 10, beads 12, a carcass 14, support layers 16, a belt 18, a band 20, an inner liner 22, and chafers 24. Dimples 62 are formed on the sidewall 8 that is at an inner side in a width direction of a vehicle when the tire is mounted on the vehicle. No dimples 62 are formed on the sidewall 8 that is at an outer side in the width direction of the vehicle when the tire is mounted on the vehicle. The ratio (Ha/Hb) of a height Ha at an outer end 52, in a radial direction, of the bead 12 from a base line BL relative to a height Hb at a maximum width position Pmax from the base line is equal to or greater than 0.80 but equal to or less than 1.10.
