Beschreibung
Zusammenfassung:	A tire comprises a tread portion provided with a first block provided with a first sipe which extends zigzag in a cross section orthogonal to the sipe length direction, and extends zigzag in a cross section parallel to the ground contacting top surface of the first block. The first sipe is divided into a first portion and a second portion by a tie bar. The sipe bottom in the first portion communicates with a first wide portion. The sipe bottom in the second portion communicates with a second wide portion. The first wide portion comprises an outer portion and an inner portion. The outer portion is formed by a pair of first arcuate groove wall portions. The inner portion is formed by a pair of second arcuate groove wall portions. The first wide portion and the second wide portion do not communicate with each other.
