Systems and methods of for tire maintenance using machine learning are provided. The system receives one or more values comprising sensor data and a unique identifier associated with the tire. The system can retrieve historical inspection data associated with the unique identifier of the tire. The system can generate a matrix comprising a first dimension based on timestamps and a second dimension based on the one or more values and the historical inspection data. The system can predict, via input of the matrix into a machine learning model constructed, an output matrix comprising an indication to perform a type of maintenance and at least one tire maintenance category. The system can provide the indication to perform the type of maintenance for the tire during the time interval and the at least one tire maintenance category.

A pneumatic tire has paired bead portions, paired sidewall portions, a tread portion, a plurality of lug grooves extending from a shoulder area of the tread portion to reach a buttress area of the sidewall portion, and a block defined by the plurality of lug grooves. The block includes a shoulder block provided in the shoulder area and a buttress block provided in the buttress area. At least some of the plurality of lug grooves end at a connecting portion connecting the paired buttress blocks, the connecting portion is provided on an inner side in the tire diametrical direction of position that are 50% of length in the tire diametrical direction of the buttress block from upper end position of the buttress block. A step or a protrusion where the buttress block has a largest upraised height is provided in the tire diametrical position of the connecting portion.

The tire is provided which has secured a traction performance in the side surface of the tire while showing a cut resistance property on the side surface of the tire. The tire includes a side block arranged on a side surface of the tire. The side block includes: a first block 11 formed on the side surface, the first block protruded from a tire surface 5 at a first height; a second block 12 formed on the side surface, the second block protruded from the tire surface at a second height different from the first height; a third block 13 formed on the side surface, the third block protruded from the tire surface at a third height different from the second height; and a fourth block 14 formed on the side surface, the fourth block protruded from the tire surface at a fourth height different from the third height.

A pneumatic tire includes a tread portion having a first tread edge, and a first buttress portion extending inwardly in a tire radial direction from the first tread edge. The first buttress portion is provided with a plurality of protectors protruding outwardly in a tire axial direction. The plurality of protectors includes a set of protectors including a first protector and a second protector arranged adjacent to the first protector via a groove extending in the tire radial direction. The groove is provided with a tie-bar connecting the first protector and the second protector. The tie-bar is partially formed in a tire radial region of the groove, and the tie-bar has a protruding height that is smaller than a protruding height of the first protector and a protruding height of the second protector.

A tire for running on rough terrain for which an intended tire rotational direction is specified. The tread portion is provided with blocks raised from a tread base portion. Each block has a first side wall surface comprising a radially outer portion extending substantially straight and radially inwardly, while inclining toward the toe side in the intended tire rotational direction, and a radially inner portion extending from the radially outer portion to the tread base portion while curving in an arc shape. The radially outer portion has a radial length of from 30% to 70% of a radial height of the block.

A tire for running on rough terrain for which an intended tire rotational direction is specified, and which comprises a tread portion provided with crown blocks disposed on the tire equator. Each of the crown blocks comprises a V-shaped crown block main portion which bends convexly toward a circumferential direction opposite to the intended tire rotation direction, and only two crown fin portions projecting from the crown block main portion toward the above-said circumferential direction opposite to the intended tire rotation direction.

In a tire, a first side block comprises a first recess which opens so as to be directed toward a first circumferential direction, and a second recess which opens so as to be directed toward a second circumferential direction which is opposite the first circumferential direction in a tire circumferential direction. The first side block comprises a first region, a second region, and a first step which is between the first region and the second region and which is formed by a difference in heights by which the first region and the second region protrude.

A pneumatic tire has paired bead portions, paired sidewall portions, a tread portion, a plurality of lug grooves extending from a shoulder area of the tread portion to reach a buttress area of the sidewall portion, and a block defined by the plurality of lug grooves. The block includes a shoulder block provided in the shoulder area, and a buttress block provided in the buttress area. The buttress area is provided with an annular rib annularly extending along a tire circumferential direction. The lug grooves are comparted into an outside lug groove positioned in an outer side of the annular rib, and an inside lug groove positioned in an inner side of the annular rib. A widened portion is provided in at least part of the plurality of lug grooves so as to enlarge a width of the annular rib.

In a pneumatic tire, a plurality of side blocks include a first side block which is contiguous with the exterior in a tire axial direction of a first tread block, and a second side block which is contiguous with the exterior in the tire axial direction of a second tread block; the first side block comprises a first apical surface which is arranged at an outer end of the first side block in the tire axial direction; the second side block comprises a second apical surface which is arranged at an outer end of the second side block in the tire axial direction, and area of the second apical surface is greater than area of the first apical surface.

An insert for a vehicle wheel suitable for being inserted in an inner annular cavity resulting between a tire and a rim of the vehicle wheel is provided. The insert has an annular element that extends in a circumferential direction (C) about a main axis (X-X), and is made in one piece of polymeric material. Dips or protrusions formed on the annular element extend about the circumferential direction (C) and along a respective preferential extension direction (A-A), which lies on a plane secant to the circumferential direction (C). A vehicle wheel having a tire, a rim, and the insert suitable for being inserted in an inner annular cavity resulting between the tire and the rim of the vehicle wheel is also provided.
