Abstract
A wear indicator provided on a tread surface is constituted of seven sipes of an uppermost sipe a lowermost sipe and an intermediate sipe each extending in a lateral direction; and an upper-left sipe an upper-right sipe a lower-left sipe and a lower-right sipe each extending in a longitudinal direction. The sipe uses a combination of an indication part used to indicate a character and a non-indication part having a narrower groove width and not used to indicate a character in a depth direction of the sipe. Single numeral is indicated by the combination of the indication parts in the seven sipes and the combination of the indication parts is changed in the depth direction of the sipe such that the numeral stepwise changes in the depth direction of the sipe.
