Claims

[Claims for Utility Model Registration] Consisting of a pair of left and right bead portions 1, a pair of left and right sidewall portions 2 connected to the bead portions 1, and a tread portion 3 located between the sidewall portions 2, A carcass layer 4 having a cord angle of substantially 90° with respect to the tire circumferential direction is mounted between the pair of bead portions 1, and a cord angle of 10° with respect to the tire circumferential direction is disposed on the carcass layer 4 in the tread portion 3. In a radial tire in which a plurality of belt layers 5 are arranged intersecting each other at an angle of ~30°, both ends of the carcass layer 4 are arranged around a pair of left and right bead wires 11 located in the bead portion 1 from the inside to the outside. The folded part 42 is brought into close contact with the carcass layer main body side 41 before folding, and the creepage distance between the end 5a of the belt layer 5 and the upper surface 11a of the bead wire 11 is 11. The terminal portion 42a of the folded portion 42 and the upper surface 1 of the bead wire 11
If the creepage distance between 1a is 1□, and the substantial contact distance of the folded portion 42 to the carcass layer main body side 41 is 13, then 1□11□≧0.4 1311□≧0.8. Radial tires.
