摘要： The environmental footprint of a tire for a construction plant vehicle is improved. To do so, the elastomer compounds derived from non-fossil resources represent a mass content greater than or equal to 65% of the total mass of the compounds of the tire, at least 75% of the total mass of the compounds of the tire is made up of elastomer compounds each of which has a viscoelastic loss, measured in terms of tan(δ), less than or equal to 0.065, and an electrical resistivity greater than or equal to 1E+10 ‘Ω·cm.

摘要： A heavy duty pneumatic tire comprises a tread pattern that comprises: circumferential main grooves with a wave-like shape, shoulder lug grooves extending in the tire width direction to a ground contact edge and connecting to the circumferential main grooves at first groove turning portions that protrude outward; center lug grooves connecting to the circumferential main grooves at second groove turning portions that protrude inward; and center blocks defined by adjacent center lug grooves of the center lug grooves adjacent in the tire circumferential direction and the circumferential main grooves, forming a row in the tire circumferential direction. The center lug grooves and the circumferential main grooves have a narrower groove width than the shoulder lug grooves; and each region of the center blocks includes two first narrow grooves having a curved line shape with no bent portions and having a narrower groove width than the shoulder lug grooves.

摘要： A tire for a construction vehicle, provided with a pair of bead cores constituting a bead portion, and a carcass straddling the bead cores and having a folded ply folded back at the bead cores. The bead portion is provided with a plurality of recessed portions arranged at intervals around the tire circumferential direction so as to be recessed from the outside of the tire towards the folded ply. When SH represents the tire section height, H1 represents the height from the rim radius to the tire-radial-direction inside edge of the recessed portions, and H2 represents the height from the rim radius to the tire-radial-direction outside edge of the recess parts, the relationships H1/SH >0.04 and H2/SH

摘要： Improving endurance of bead of radial tire for heavy vehicle. Tire has two beads (2) contacting rim (3) connected by carcass reinforcement (4) having carcass layer (5), with main part (6) wrapped, in each bead (2), axially from inside towards outside of the tire, around bead wire (7) having diameter (L), to form turnup (8) having free end (E). Each bead (2) has filling element (9) with filling compound (10) and extending radially towards outside from bead wire (7) and axially between turnup (8) and main part (6). The distance (I) between turnup (8) and main part (6) decreases continuously from bead wire (7) as far as a first minimum distance (a) reached at a first point (A) of turnup (8), then increases continuously from the first point (A) of turnup (8) as far as a first maximum distance (b) reached at a second point (B) of turnup (8).

摘要： A tread pattern is provided with: shoulder lug grooves open at ground contact ends; center lug grooves each having opposite ends; circumferential primary grooves each formed in a wavy shape by connecting ends of the center lug grooves and the inner ends of the shoulder lug grooves in the width direction of the tire; and center blocks defined by the center lug grooves and the pair of circumferential primary grooves. The width of the circumferential primary grooves is smaller than the width of the shoulder lug grooves. The center lug grooves are tilted relative to both the circumferential direction and the width direction of the tire and each have a third groove turning portion and a fourth groove turning portion which protrude in the different directions in the circumferential direction of the tire.

摘要： The tire has a crown part with sidewalls that end in beads. The crown part has a tread and a crown reinforcement. The crown reinforcement has protective, working and additional reinforcements. The protective reinforcement has a protective layer with elastic metal reinforcers which form an angle at least equal to 10°. The working reinforcement has working layers with crossed metal reinforcers and forming, with the circumferential direction, an angle at most equal to 60°. The additional reinforcement has a layer with an axial width at most equal to 0.9 times the shortest of the axial widths of the working layers and comprising metal reinforcers which form an angle at most equal to 25°. A tread pattern design of the tread has circumferentially oriented grooves. The mean axial distance between the two grooves closest to the equatorial midplane is greater than the maximum axial width of the additional reinforcement.

摘要： In a pneumatic tire 1, a side surface (101), on a buttress portion (14) side, of a land portion block (100) is inclined to the inside of the land portion block (100). The length (Lb1), in a tread width direction, of an and portion (100B) of the land portion block (100) is smaller than the length (La1), in the tread width direction, of an end portion (100A). The end portion (100B) is located at a rear side in a rotational direction (R) in which the pneumatic tire (1) installed on a vehicle rotates when the vehicle moves forward, and the end portion (100A) is located at a front side in the rotational direction (R).

摘要： A pneumatic tire construction is described suitable for severe loading conditions. The tire includes a bead portion further having an apex which extends radially outward of the bead core, and a first turn-up pad located adjacent said chafer, and a second turn-up pad located adjacent said first turn-up pad, wherein the first turn-up pad has a G′ less than the G′ of the second turn-up pad. Alternatively, the first turn-up pad may be located adjacent to the rim flange and the second turn-up pad may be located axially inward of the first pad. The second turn-up pad is preferably thicker and longer than the first turn-up pad.
