<p>A belt (12) of a tire includes a first belt ply (28), a second belt ply (30) and a third belt ply (32). The first belt ply (28) has a first cord (34). The first cord (34) has an angle ± with respect to a circumferential direction which is equal to or greater than 15 degrees and is equal to or smaller than 40 degrees. The second belt ply (30) has a second cord (38). The second cord (38) has an angle ² with respect to the circumferential direction which is equal to or greater than 15 degrees and is equal to or smaller than 40 degrees. The second cord (38) is inclined in a reverse direction to the first cord (34) about an equator plane. The third belt ply (32) has a third cord (42) . The third cord (42) is wound spirally and is extended substantially in the circumferential direction. A ratio of a width (Wb) of the belt (12) to a width (Wt) of a tread is equal to or higher than 80% and is equal to or lower than 100%.</p> |
