PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of more surely improving drain performance, when mounted in a vehicle set with a camber angle of a negative camber, etc. SOLUTION: This pneumatic tire 1 includes land parts 20 formed by a main groove 12 extending along a tire peripheral direction. The main groove 12 is provided at the vehicle mounting time inside IN or the vehicle mounting time outside OUT in relation to a tire equator line CL. The land parts 20 include a land part 22 having a groove wall 22A forming one wall surface of the main groove 12 and a land part 23 having a groove wall 23A forming the other wall surface of the main groove 12. The groove wall 22A and the groove wall 23A meander along a tire peripheral direction in the tread view. In at least one of the land part 22 or the land part 23, a divided lug groove 40A2 or a divided lug groove 40A3 extending in a tread width direction and communicated with the main groove 12 is formed. A groove width W of the main groove 12 along the tread width direction changes at a prescribed repetition interval along the tire peripheral direction. COPYRIGHT: (C)2011,JPO&INPIT |
