Abstract

A tire has cap rubber that forms a contact patch. The cap rubber has a plurality of lugs. A shoulder lug, which among the plurality of lugs is that which is located outwardmost in a tire width direction, has a narrow groove that extends in the tire circumferential direction and that partitions the shoulder lug into a main lug portion toward the interior in the tire width direction, and a sacrificial lug portion toward the exterior in the tire width direction; and low-modulus rubber, for which stress at a given elongation is lower than that of the cap rubber, is arranged at a corner where the contact patch at the main lug portion and a groove side face toward the interior in the tire width direction which forms the narrow groove intersect.
