Patent ID: 10723179

Abstract:
A tire has a tread portion including a groove extending in the tire-circumferential direction, a first land portion positioned to the inner-side in the tire-width direction and having a first groove wall of the groove, and a second land portion having a second groove wall. Protrusions extend from the first groove wall to the second groove wall on bottom of the groove. In a tread-surface view, the protrusion has a linear portion and a curved portion that is contiguous with the linear shaped portion. A slit crossing the protrusion is formed in at least one of the end parts of the protrusions. The first land portion includes shallow grooves having shallower depth than the groove and extending at an angle with respect to the tire-width direction. The linear portion of the protrusion extends at an angle in the same direction, with respect to the tire-circumferential direction, as the shallow grooves.
