Abstract: Provided is a pneumatic tire. Center blocks in a center region of a tread section are arrayed to form a pair between which are interposed inclined grooves inclined with respect to a circumferential direction. The center blocks straddle an equator from one side to the other. Notches composed of a first and second walls connected in a V shape are in treads in each center block. The first walls extend at an angle within ±20° with respect to the circumferential direction. The second walls extend at an angle of ±10° with respect to a width direction. Inclined grooves are each constituted by a see-through portion and an expanded portion having a larger groove width than the see-through portion. A width of a see-through region that can extend without intersecting an extension line of the see-through portion is made to be equal to or greater than 30% of a tread width.

Abstract: A pneumatic tire is provided. Center blocks in a center region are in pairs across grooves inclined with respect to a circumferential direction. Each of the center blocks extends from one side to the other of an equator and includes a notch defined by a first and second walls connected in a V-shape in a tread contact surface. The first wall extends within ±20° of the circumferential direction, the second wall extends within ±10° of a lateral direction, an average angle of sipes formed in one of the center blocks and the shoulder blocks is smaller than or equal to 90°±10° with respect to the equator for a first region, smaller than or equal to 130°±10° for a second region, and smaller than or equal to 70°±10° for a third region, and each of the sipes includes at least one bent portion.

Abstract: In a pneumatic tire, center blocks in a center region of a tread portion form a pair sandwiching an inclined groove that extends inclined with respect to a circumferential direction. Each of the center blocks extends across an equator and includes a notch formed of first and second walls that are connected in a V-shape in a tread road contact surface. The first wall extends within +/−20° with respect to the circumferential direction, and the second wall extends within +/−10° with respect to a lateral direction. Each of shoulder blocks provided in a center region of the tread portion includes a third wall opposed to the notch and at an angle within +/−5° with respect to a straight line connecting an end point of the first wall, located adjacent to the shoulder block and an end point of the second wall, located adjacent to the shoulder block.
