摘要:
A shoulder land portion includes a main body land portion formed between a thin groove extending in a tire circumferential direction on a tire width direction inner side of a ground contact end and a shoulder main groove, and the main body land portion includes a contact region adjacent to the shoulder main groove provided along the tire circumferential direction and a non-contact region provided along the tire circumferential direction between the thin groove and the contact region. The contact region contacts a road surface in a normal load state, and the non-contact region is recessed to a tire radial direction inner side from a tread surface. The non-contact region does not contact the road surface in the normal road state, and when a length of the non-contact region is W1 and a length of the main body land portion both along the tire width direction is Rw, 0.2Rw≤W1≤0.5Rw.
