Pneumatic tire

摘要

A pneumatic tire including a plurality of circumferential main grooves extending in a tire circumferential direction, a plurality of land portions partitioned by the circumferential main grooves, a narrow groove extending in the tire circumferential direction and disposed in an edge portion of a road contact surface side and an outer side in the tire width direction of the shoulder land portion on an outermost side in a tire width direction, and a narrow rib that is partitioned by the narrow groove. The narrow rib includes an offset portion having a road contact surface offset inward in a tire radial direction from the road contact surface of the shoulder land portion, and a protrusion protruding in the tire radial direction from the offset portion, extending in the tire circumferential direction, and having a top surface that is substantially flush with a profile line of the shoulder land portion.
