Abstract
This tire is provided with reinforcing cord layers that reinforce a bead part. The reinforcing cord layers are such that at the bead part at the inner side of vehicle mounting, the number of layers of the reinforcing cord layers with respect to a bead filler is greater at the inner side in the direction of tire width compared to the outer side in the direction of tire width with respect to the bead filler, and at the bead part at the outer side of vehicle mounting, the number of layers of the reinforcing cord layers with respect to the bead filler is greater at the outer side in the direction of tire width compared to the inner side in the direction of tire width with respect to the bead filler.
Claims7
A tire in which a mounting direction to a vehicle is designated, the tire comprising:
- a tread part configured to be in contact with a road surface;
- a pair of bead parts including a bead core and a bead filler;
- a carcass layer folded around the bead core and extended toroidally between the pair of bead parts;
- and
- a reinforcing cord layer having a cord configured to reinforce the pair of bead part, wherein
- in a vehicle inner side bead part, a number of layers in the reinforcing cord layer is larger on an inner side in a tire width direction with respect to the bead filler than on an outer side in the tire width direction with respect to the bead filler,
- in a vehicle outer side bead part, a number of layers in the reinforcing cord layer is larger on the outer side in the tire width direction with respect to the bead filler than on the inner side in the tire width direction with respect to the bead filler, and
- a density of the cord in the reinforcing cord layer in the vehicle outer side bead part is larger than a density of the cord in the reinforcing cord layer in the vehicle inner side bead part.
