PROBLEM TO BE SOLVED: To provide a tire allowing sure suppression of generation of uneven wear, while improving drainage property, when a main groove is formed. SOLUTION: This pneumatic tire 1 includes at least a land part formed by the main groove 50 along a tire peripheral direction TC. The land part includes a land part 10 including a groove wall 10a to form the main groove 50, and a land part 20 including a groove wall 20a to form the main groove 50. The groove wall 10a and the groove wall 20a meander along the tire peripheral direction TC in a tread surface view. A groove width of the main groove 50 along the tread width direction TW is changed at a prescribed repeated period along the tire peripheral direction TC. The main groove 50 includes a wide groove part 50A having a groove width of a prescribed width, and a narrow groove part 50B continuous to the wide groove part 50A and narrower than the prescribed width. A narrow depth D1 of the narrow groove part 50B is deeper than a wide depth D2 of the wide groove part 50A. COPYRIGHT: (C)2011,JPO&INPIT |
