A tire for an agricultural vehicle, having a tread made of rubbery material and two axially outer zones delimiting the tread, each having a shoulder and a sidewall and designed to mechanically connect the tread to a rim. The tire has a plurality of blocks distributed in a circumferential direction (X), each block having a length L, measured in the circumferential direction (X) from a lateral face of the block, and a height H, where L is greater than H. Each block has a cavity that opens onto the lateral face, forming an opening in the lateral face. The cavity has a depth p and an opening width l. The blocks are present in at least one of the two axially outer zones, but not in the tread. The blocks are present at the shoulder in the continuation of the tread.

A tire may comprise a hub and a plurality of discrete traction elements coupled to the hub. Each of the traction elements may comprise a backing plate and an elastomeric material bonded to the backing plate. Circumferentially adjacent traction elements may axially overlap.

The present disclosure relates to a method and manufacturing method for a tire tread composition having absorption properties with high electric conductivity and excellent wear resistance. Specifically, the present disclosure relates to the fabrication of a tire composition to be used as a non-pneumatic tire, the tire composition can be used as a mobile electrode with a water supply means that can identify the location of defects in the buried conductor using the tire electrode manufacturing with improved conductivity and contact resistance with the ground even though the tire compound has wear resistance by lowering the water swelling rate compared to the previous technology.

A pneumatic tire includes a tread portion with shoulder lug grooves spaced apart in a circumferential direction, each extending outward in a tire lateral direction, opening to a ground contact end, and including a closed end inward in the tire lateral direction. In a region of each of the shoulder lug grooves from an end of a belt having a greatest width in a belt portion of the pneumatic tire to an inner side in the tire lateral direction, the shoulder lug groove has a groove width that decreases inward in the tire lateral direction, and includes a portion where a groove cross-sectional area is kept constant by a change in at least one of a groove wall angle or a groove depth of the shoulder lug groove, the portion being provided in the tire lateral direction across a length of at least 20% of half a tire development width.

A tire (1) for an agricultural vehicle, having a crown reinforcement (3), with at least two crown layers (31, 32), each having metal reinforcers which are coated in an elastomer material. Any metal reinforcer of a crown layer (31, 32) has a law, known as a bi-modulus law, governing its elastic behaviour under tension, comprising a first portion having a first extension modulus MG1 at most equal to 30 GPa, and a second portion having a second extension modulus MG2 at least equal to 2 times the first extension modulus MG1, and any metal reinforcer of a crown layer (31, 32) has a law governing its behaviour under compression that is characterized by a critical buckling strain EU at least equal to 3%.

Segmented tires employ segments featuring cooperating recesses and protrusions at opposing sides thereof for mating of the segments with one another in the assembled tire body. Cleated tires with embedded cleats of greater rigidity than the tire body material provide improved traction in muddy or other slippery conditions while the compressible tire body smooths out the ride harshness of the tire. Mounting elements are also embedded within the segments of the tire body for secure mounting and reliable retention of the segments.

A pneumatic tire includes two circumferential main grooves disposed in an inner half of a tread developed width in a tire lateral direction; shoulder lug grooves that divide shoulder land portions into shoulder block portions and that each include a see-through portion in the tire lateral direction; center lug grooves dividing a center land portion into a plurality of center block portions; and center sipes having both ends terminated in the center block portions. The center sipe includes at least two sipe portions having different angles via at least one bent portion. An angle θ.sub.1 of at least one sipe portion with respect to a tire equator line satisfies 0°≤θ.sub.1≤15°, and an angle θ.sub.2 of at least the other sipe portion with respect to the tire equator line satisfies 35°≤θ.sub.2≤60°.

A tread pattern of a heavy duty pneumatic tire includes: a linear shaped center lug groove; a pair of circumferential main grooves formed in a wave shape in a tire circumferential direction; a center block; and a central narrow groove that does not have a linear shape, having an opening end that opens in the adjacent center lug grooves in a tire lateral direction position excluding on a tire equator line, and having a groove width that is narrower than the groove width of the shoulder lug groove. The groove width of the center lug groove and the circumferential main groove is narrower than the groove width of the shoulder lug groove. The central narrow groove has a portion that extends outwards in a tire lateral direction from the opening end in the half tread region where the opening end is positioned.

A center block of a construction vehicle tire is formed in a range of ⅛-⅜, inclusive, of a tread width. A width direction narrow groove is terminated in the center block. A notch groove includes outer grooves formed at each end side of the narrow groove, and inner grooves formed between the outer grooves. A slope portion of the outer groove is inclined to be close to an inner side in the tire radial direction toward one side in the tire circumferential direction. A slope portion of the outer groove is inclined to be close to the inner side in the tire radial direction toward another side in the tire circumferential direction. A slope portion of each inner groove is inclined to be close to the inner side in the tire radial direction toward one side or another in the tire circumferential direction.

A first land region is defined between a first main groove and a second main groove extending in a tyre circumferential direction. The first land region is provided with a first oblique groove and a second oblique groove. The first oblique groove extends obliquely with respect to a tyre axial direction from the first main groove to have an end portion terminating within the first land region. The second oblique groove extends obliquely with respect to the tyre axial direction from the second main groove to intersect with a middle groove portion of the first oblique groove and terminate there.
