ABSTRACT:
A pneumatic tire comprises sipes in each land portion defined by wide-width grooves in a tread portion, in which a sipe corresponding to at least a part of these sipes comprises a pair of main portions slightly shifting to each other in the axial direction and a link portion connecting opposed end portions of these main portions to each other, and the pair of the main portions are inclined in opposite directions with respect to a radial direction so as to make a mutual distance L between the main portions large.
