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.
