Abstract
A tire includes a tread portion provided with a plurality of blocks. At least one of the plurality of blocks is provided with a sipe. The sipe extends in a sipe longitudinal direction to form a zigzag opening configuration on a ground contact surface of the at least one of the plurality of blocks. The sipe extends inwardly in a tire radial direction such that the zigzag opening configuration oscillates in the sipe longitudinal direction repeatedly with a total amplitude and a wavelength while maintaining the zigzag opening configuration. A half of the wavelength of the sipe is in a range of from 0.10 to 0.24 times a maximum depth of the sipe, and a slope of the half of the wavelength with respect to the total amplitude has an angle in a range of from 45 to 65 degrees.
