To enhance uniformity, abrasion resistance and durability while minimizing manufacturing cost in an automatic two-wheeled vehicle large in the falling ratio of a tread.
By forming at least the outermost layers 24 in the end part regions 20B of the tread 20 as spiral treads, a production time (the time of winding a rubber strip 22) is made short as compared with that the spiral tread is formed over the whole width of the tread 20, manufacturing cost can be suppressed, the wrinkling or the like due to the squeezing at the time of molding of the tire is eliminated in a tread end parts large in falling ratio and tread thickness is uniformized. Accordingly, uniformity improves to make no chattering occur at the time of an actual car. Further, by employing the spiral tread in the end part regions 20B, the abrasion resistance and durability in the end part regions 20B are enhanced.
