Abstract
A main object is to provide a tire that suppresses snow clogging of sipes. The tire includes a tread portion. The tread portion includes a first land portion demarcated by circumferential grooves continuously extending in a tire circumferential direction, and a plurality of first lateral grooves inclined in a first direction relative to a tire axial direction and traversing the first land portion. The first land portion includes a plurality of first blocks demarcated by the first lateral grooves. Each first block has at least one sipe inclined in a second direction opposite to the first direction, relative to the tire axial direction. The sipe includes a portion deeper than a maximum depth of the first lateral groove, and a portion shallower than the maximum depth of the first lateral groove.
