Abstract: A pneumatic tire includes two circumferential main grooves disposed in an inner half of a tread developed width in a tire lateral direction; shoulder lug grooves that divide shoulder land portions into shoulder block portions and that each include a see-through portion in the tire lateral direction; center lug grooves dividing a center land portion into a plurality of center block portions; and center sipes having both ends terminated in the center block portions. The center sipe includes at least two sipe portions having different angles via at least one bent portion. An angle ?1 of at least one sipe portion with respect to a tire equator line satisfies 0°??1?15°, and an angle ?2 of at least the other sipe portion with respect to the tire equator line satisfies 35°??2?60°.

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.
