In a pneumatic tire, high and low blocks with different heights are provided in a side region. High and low blocks adjacent in a circumferential direction form a block pair. The high and low blocks in the block pair are partially in contact with each other. A side groove between these blocks is a closed groove. In each block pair, contour lines including first, second and third linear portions, define edges on both sides in the tire circumferential direction, of a top surface of each of the high and low blocks. The first linear portions and one of the second linear portions or the third linear portions extend in an identical direction with an angle difference being equal to or smaller than 15 degrees. Other linear portions of the second linear portions or the third linear portions extend in different directions.

A pneumatic vehicle tire including a utility vehicle tire has a tread with profile positives which are separated from one another in a circumferential direction by transverse channels which extend continuously from the central region of the tread as far as the lateral tread edges, respectively. The transverse channels are main channels of the tread and, at least over the major part of the course thereof, have the maximum provided profile depth. The transverse channels are provided, on the respective channel base thereof, with a row of base elevations formed so as to be distributed over the entire course of the transverse channels. The base elevations are attached to the channel flanks of the transverse channels and are configured such that their rubber volume becomes smaller the closer to the tread edge they are disposed.

In a pneumatic tire, a tread portion is provided with center blocks and shoulder blocks, and sidewall portions are each provided with side blocks. Surfaces of the blocks are provided with groove elements each including a narrow groove and/or a sipe. The first groove elements provided in the side blocks, the second groove elements provided in the shoulder blocks, and the third groove elements provided in the center blocks form a set of lateral groove group extending continuously from the side block on a first side to the side block on a second side in the tire lateral direction along the blocks across a main groove or an auxiliary groove.

A wheel for a vehicle (e.g., a construction vehicle, an all-terrain vehicle, or other off-road vehicle) or other device, in which the wheel includes a non-pneumatic tire that may be designed to enhance its use and performance, including to be able to be used longer and/or in more challenging conditions, such as by being more resistant to cracking or other damage which could lead to premature failure (e.g., due to manufacturing artifacts and/or rocks and other hazards that can cut, chip, or tear during use). The non-pneumatic tire includes an annular beam configured to deflect at a contact patch of the non-pneumatic tire and an annular support extending radially inwardly from the annular beam and configured to support loading by tension. An elastomeric material of at least one of the annular beam and the annular support may have selected properties, including greater crack propagation resistance when subject to tensile stress.

A tire comprises a tread portion 2. The tread portion 2 has a repeated pattern portion 7 in which a plurality of minimum pattern constituent units 8 is arranged in a tire circumferential direction. Each of the minimum pattern constituent units 8 includes a center block 10, a plurality of surrounding blocks 11 surrounding the center block 10, and dividing grooves 15 each arranged between adjacent ones of the plurality of the surrounding blocks 11. The dividing grooves 15 include first dividing grooves 16 and second dividing grooves 17 inclined in opposite directions to each other.

A pneumatic tire includes blocks (36 and 41) formed by main grooves (10 and 15) extending in a circumferential direction of the tire and lateral grooves (20 and 25) extending in a tire width direction, and notches (50, 60, and 70) in stepped side end portions of the blocks (36 and 41). The lateral grooves (20 and 25) extend obliquely such that a tire grounding end (E) side is grounded later. Portions adjacent to the notches (50, 60, and 70) on the tire grounding end (E) side of the notches (50, 60, and 70) are protrusions (51, 61, and 71) protruding while forming an acute angle toward a tire equator (C) side.

The tire can achieve both cut resistance and mud drainage performance of the sidewall. The tire includes: a tread; sidewalls; and a plurality of side block groups on at least one of the sidewalls. Each of the side block groups protrudes from the sidewall reference plane. Each of the side block groups includes: a first side block; and a second side block. In each of said plurality of side block groups, the fi3 . . . 3rst side block 2 has a groove 23 extending from the second side block 3 toward an inside of the first side block in the tire circumferential direction D3, In each of said plurality of side block groups, the second side block 3 has a slope 35c whose height from the reference plane S2 becomes lower toward the first side block, such that the slope extends into the groove of the first side block.

A tread of a tire includes a plurality of blocks including a center block located on an equator plane and a side block located outward of the center block in an axial direction. Each of the plurality of blocks includes a land surface that forms a part of a tread surface. In the tread surface, a total area of the land surfaces is smaller than a total area of a portion other than the land surfaces. A complex elastic modulus at a maximum strain amplitude of 1% and a temperature of 70° C. of each block is not less than 10.0 MPa. A 300% modulus at a temperature of 75° C. of each block is not greater than 6.0 MPa.

The pneumatic tire includes a carcass layer, a belt layer disposed on an outer side of the carcass layer in a radial direction, and a tread rubber disposed on an outer side of the belt layer in the radial direction. Additionally, the carcass layer has a cord angle of 80° or more and 100° or less. Additionally, the belt layer is formed by layering a first reinforcing belt, a second reinforcing belt that is narrower than the first reinforcing belt, and an auxiliary belt that is spaced apart from a tire equatorial plane and disposed between the carcass layer and the first reinforcing belt. Additionally, the first reinforcing belt has a cord angle of 11° or more and 30° or less, the second reinforcing belt has a cord angle of 1° or more and 11° or less, and the auxiliary belt has a cord angle of 55° or more and 70° or less.

A pneumatic tire includes: a main groove extending in a tire circumferential direction disposed on a shoulder region of a tread portion; lug grooves extending from the main groove toward an outer side and reaching a side wall portion; and blocks demarcated by the main groove and lug grooves. An edge on an innermost side in a tire radial direction of the blocks is positioned more on an outer side in the tire radial direction than a tire maximum width position, and a ratio of an orthogonal distance from a ground contact end position to the edge on an innermost side in the tire radial direction of the blocks is 0.2 or more. Recessed portions each having a closed periphery are provided in a side region more on an outer side in a tire width direction than the ground contact end of the blocks.
