Abstract:
The pneumatic tire of this disclosure comprises on a tread surface a widthwise outermost land portion partitioned by an outermost circumferential main groove and a tread edge, wherein: the widthwise outermost land portion has a plurality of side sipes extending to a tread widthwise outer side in a manner spaced from each other in the tread circumferential direction; the widthwise outermost land portion has an inner circumferential sipe and an outer circumferential sipe, the inner circumferential sipe extending in the tread circumferential direction, the outer circumferential sipe being positioned on a tread widthwise side outer than the inner circumferential sipe and extending in the tread circumferential direction; and, when h1 is a groove depth of the outermost circumferential main groove, h2 is a sipe depth of the inner circumferential sipe, and h3 is a sipe depth of the outer circumferential sipe, h1, h2 and h3 satisfy: h1>h3>h2.
