Abstract
The pneumatic tire includes, on a tread surface, at least two circumferential main grooves and at least one rib-like land portion defined by two of the circumferential main grooves. The rib-like land portion includes neither grooves nor sipes that extend to include a widthwise center line of the rib-like land portion. The rib-like land portion includes a one-end-open sipe and a both-end-closed sipe. The one-end-open sipe has a widthwise sipe portion and a circumferential sipe portion, the widthwise sipe portion extending in tire width direction from one end of the one-end-open sipe and being terminated within the rib-like land portion, and the circumferential sipe portion being located closer to the widthwise center line than the both-end-closed sipe, extending in tire circumferential direction from the widthwise sipe portion, and being terminated at another end of the one-end-open sipe.
