Pneumatic tire

Abstract

The weight of a tire is reduced whilst maintaining wet weather performance. A pneumatic tire includes a lug groove (34) positioned to a tire radial direction outside of a tire width direction outside edge portion (belt edge (18A)) of a belt layer (18), and a raised bottom portion (36) that is disposed at a position in the lug groove (34) corresponding to the tire width direction outside edge portion (18A) of the belt layer (18) with a bottom raised in comparison to the groove bottom (34A) at a general portion of the lug groove (34). The raised bottom portion (36) is set at a position corresponding to the belt edge (18A), allowing the volume of the lug groove (34) to be maintained and a rubber gauge (D6) between the lug groove (34) bottom and the belt edge (18A) to be secured even though the rubber gauge of a tread portion (20) overall is suppressed.
