Abstract

PURPOSE:To improve durability and tire motion characteristic by constituting a reinforcing carcass with steel cords formed by twisting a specified sliver wire in a specified manner and arranging the carcass around a bead wire so that the carcass is wound and turned up to near the top end of a rim flange. CONSTITUTION:A reinforcing carcass ply is formed by embedding steel cords formed by twisting metallic filament slivers, with the number of the twisted cords being 1+(1Xn) where n is the number of the sliver wires, in rubber. Here steel cords are arranged such that the thickness of the rubber D between cords measured in the tire circumferential direction at the maximum tire width position is in the range of 0.80-2.00mm. Further, the product of the number of slivers n and the 4th power of the diameter of the sliver dmm is made to be in the range of 0.002-0.012. Both ends of the reinforcing carcass are wound up outward around a bead wire as far as near the top end of a rim flange to form a ply turnup portion. With this constitution, both tire motion performance and durability are improved.
