A tire according to the present disclosure is a tire including, in a tread surface, a block-shaped land portion partitioned by a partitioning groove or by the partitioning groove and a tread edge. The block-shaped land portion includes a first sipe and a second sipe extending from different positions in a surface of the block-shaped land portion inwardly in a tire radial direction. The first sipe includes, on a side of a sipe bottom, a widened portion with a larger sipe width than a side of the tread surface. The second sipe includes a plurality of holes recessed inwardly in the tire radial direction in a sipe bottom at positions separate in a sipe longitudinal direction.

A motorcycle tyre has a tread band including a central portion and two shoulder portions arranged at axially opposite sides of the central portion. The central portion includes a first plurality of grooves extended according to a substantially longitudinal direction and alternatively arranged at opposite sides of the equatorial plane of the tyre. Each groove of the first plurality of grooves has a substantially curvilinear course such as to form a concavity. The central portion further includes a sub-portion substantially free of grooves placed astride the equatorial plane of the tyre. Each of the shoulder portions includes a second plurality of grooves arranged obliquely relative to the equatorial plane of the tyre.

A pneumatic tire includes a first tread-half region from the tire equator to a first tread edge. In the first tread-half region, a crown land portion and a middle land portion are not provided with any grooves having widths equal to or more than 2 mm. In the first tread-half region, crown, middle and shoulder portions are respectively provided with a first crown sipe, a first middle sipe and a first shoulder sipe each having a width less than 2 mm. The first crown sipe, the first middle sipe and the first shoulder sipe are respectively configured as arc shapes having radiuses R1, R2 and R3 of curvature to protrude in a first circumferential direction side, wherein the radiuses R1, R2 and R3 are satisfied the following relation: R1<=R2<=R3, and R1<R3.

All season tyre (1) for SUVs and Crossovers; the tyre having a tread band (7) provided with a plurality of sipes (21,22,23,24,25,26) regularly and homogeneously arranged, and a wide central region (LI) provided with three rows of blocks, at least wo of which are provided with transverse grooves only slightly inclined relative to a direction orthogonal to the equatorial plane. The central region (LI) lacks circumferential annular portions having a low void-to-rubber ratio located adjacent to central annular portions having a medium or high void-to-rubber ratio.

A wheel assembly of a vehicle (e.g., a forklift or another material-handling vehicle) is monitored to obtain information regarding the vehicle, including information regarding the wheel assembly, which may be indicative of how the vehicle including the wheel assembly is used (e.g., a duty cycle of the vehicle and/or the wheel assembly), a state (e.g., a degree of wear) of the wheel assembly, loading and shocks on the wheel assembly, and/or a state of an environment (e.g., environmental temperature, a profile, compliance, or other condition of an underlying surface beneath the wheel assembly), and which may be, for example, conveyed to a user (e.g., an operator of the vehicle), transmitted to a remote party (e.g., a provider), and/or used to control the vehicle (e.g., a speed of the vehicle). This may improve use, maintenance, safety and/or other aspects of the vehicle, including the wheel assembly.

A tire has a tread portion including a first land portion including first and second circumferential edges and and a tread surface. On the first land portion, curved grooves are provided in a tire circumferential direction. Each curved groove extends from a first end on the first circumferential edge side, terminates at a second end within the first land portion, and includes first and second curved portions and on the first end and second end sides, respectively. The first curved portion is an arc curve with a radius of curvature having a center on the first circumferential edge side of the curved groove. The second curved portion is an arc curve with a radius of curvature having a center on the second circumferential edge side of the curved groove.

A tread portion has an outer tread end that is positioned on an outer side of a vehicle when mounted to the vehicle, a plurality of circumferential grooves that extend continuously in a tire circumferential direction, and a plurality of land portions that are defined by the circumferential grooves. The circumferential grooves include an outer circumferential groove that extends adjacently to a tire equator in a region closer to the outer tread end than the tire equator is. The land portions include an outer shoulder land portion that is defined between the outer circumferential groove and the outer tread end so as to continuously extend therebetween in a tire axial direction, and that has the largest width in the tire axial direction among the land portions. The outer shoulder land portion has a first outer lateral groove that extends inward in the tire axial direction and terminates in the outer shoulder land portion. An angle of the first outer lateral groove relative to the tire axial direction at a terminating position in the outer shoulder land portion is 0 to 20°.

A tire tread pattern includes: first sipes in a first land portion between first and second circumferential main grooves; first chamfered surfaces in which a tread surface of the first land portion is inclined toward a first circumferential main groove side in an end portion in a width direction, the first sipes opening to the first chamfered surfaces; second sipes in a second land portion on an opposite side of the first land portion with respect to the second circumferential main groove; and second chamfered surfaces in which a tread surface of the second land portion is inclined toward a second circumferential main groove side in an end portion in the width direction, the second sipes opening to the second chamfered surfaces. The first and second. chamfered surfaces are greater in length in the circumferential direction than in the width direction.

A tread pattern of a tire includes: a circumferential main groove extending in a tire circumferential direction; a plurality of sipes extending in a tire width direction within a region of a land portion in contact in the tire width direction with the circumferential main groove; and a chamfered surface having a tread surface of the land portion inclined toward the circumferential main groove in an end portion in the tire width direction on a circumferential main groove side of the land portion, the chamfered surface being provided in a plurality in the tire circumferential direction, and the sipes opening to the plurality of the chamfered surfaces without reaching a groove wall of the circumferential main groove. The length of the chamfered surface in the tire circumferential direction is greater than the length thereof in the tire width direction.
