Abstract: A pneumatic tire can include a pair of sidewall portions, where an outer surface of the sidewall portion can include a marking portion. The marking portion can include a first region forming a mark, a second region that is a background portion of the mark, and a fringing portion that demarcates the first region from the second region and fringes the contour of the mark. The first region can be formed as a smooth surface. The second region can be a projection-recess region where a plurality of micro projections are arranged. The fringing portion can be a rib projecting from the first region.

Abstract: A tire includes a tread portion including a first tread edge, a first shoulder circumferential groove, and a first shoulder land portion demarcated by the first shoulder circumferential groove to include the first tread edge. The first shoulder land portion is provided with first shoulder lateral grooves extending from the first shoulder circumferential groove to the first tread edge. One of the first shoulder lateral grooves includes first and second groove walls which face each other, and a tie-bar. The tie-bar includes an outer surface extending along a ground contact surface of the first shoulder land portion, the outer surface being connected to the first and second groove walls. The outer surface includes a first edge connected to the first groove wall, and a second edge connected to the second groove wall, the second edge having a length smaller than a length of the first edge.

Abstract: A tire comprises a tread portion including a first land portion provided with axially extending first lateral sipes. The first lateral sipe has a first sipe wall and a second sipe wall, and opens at a ground contacting top surface via a chamfer portion. The chamfer portion comprises a first sloped surface and a second sloped surface respectively connected to the first sipe wall and the second sipe wall. In a top view of the first land portion, the width W1 of the first sloped surface is larger than the width W2 of the second sloped surface.

Abstract: A tire includes a tread portion including a first shoulder land portion provided with first shoulder lateral grooves extending from a first tread edge to a first shoulder circumferential groove, a second shoulder land portion provided with second shoulder lateral grooves extending from a second tread edge and terminating within the second shoulder land portion, a first middle land portion provided with first middle lateral grooves extending from the first shoulder circumferential groove and terminating within the first middle land portion, a second middle land portion provided with outer and inner second middle lateral grooves respectively extending from the second crown circumferential groove and the second shoulder circumferential groove and terminating within the second middle land portion, and a crown land portion provided with crown lateral grooves extending from the first crown circumferential groove and terminating within the crown land portion.

Abstract: A tire includes a tread portion being provided with a first circumferential groove extending continuously in the tire circumferential direction, and a first land portion adjacent to the first circumferential groove. The first land portion includes a ground contact surface, a land sidewall on a first circumferential groove side, and a recess that opens across both the ground contact surface and the land sidewall. The recess has an opening defined by a V-shaped first edge and a V-shaped second edge respectively extending on the ground contact surface and the land sidewall. The recess has a circumferential maximum length L1 of from 6.0 to 9.0 mm. The recess has a maximum depth d1 of from 15% to 40% of a maximum depth of the first circumferential groove. The recess has an axial maximum length L2 of from 3.0 to 5.0 times the depth d1.

Abstract: A tire includes a tread formed with: circumferential grooves extending continuously in a tire circumferential direction; lateral grooves connecting the circumferential grooves in a tire axial direction; and blocks divided by the circumferential grooves and the lateral grooves. In the lateral groove, a groove bottom is raised to form a tie bar connecting the blocks in the tire circumferential direction. The tie bar is formed with a groove portion penetrating the tie bar in the tire axial direction. In a state where the tire is assembled to a regular rim, filled with a regular internal pressure, loaded with a regular load, and contacting a flat surface at a camber angle 0°, a side wall formed on the tie bar by the groove portion on one side in the tire circumferential direction does not contact a side wall on the other side in the tire circumferential direction.

Abstract: A tire includes a tread portion provided with lateral grooves extending in a tire axial direction and blocks divided by the lateral grooves. At least one of the lateral grooves is provided with a first projected portion with a bottom protruding from a groove bottom of the at least one of the lateral grooves. The first projected portion includes at least one tie-bar portion connecting a pair of blocks with each other which is arranged adjacently through the at least one of the lateral groove, and a narrow rib-portion extending in a longitudinal direction of the at least one of the lateral groove from the at least one tie-bar portion without being connected to the pair of blocks.
