<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire that prevents peeling-off of a reinforcing layer and improves tire durability at a bead part. <P>SOLUTION: The pneumatic tire includes a carcass layer and a plurality of bead side-face reinforcing layers. The carcass layer is a layer formed by being folded back from the inside to the outside of the tire around a bead core. The plurality of bead side-face reinforcing layers are arranged on the outside of the part where the carcass layer is folded back to the outside, and have a plurality of reinforcing wires inclined at an angle with respect to the tire circumferential direction and the tire radial direction. A stress relaxation rubber layer is arranged between the plurality of bead side-face reinforcing layers near the end on the tread side of the plurality of bead side-face reinforcing layers. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
