Abstract: An improved off-the-road pneumatic tire designed to be mounted on an associated design rim having a flange portion is described. The rim flange has an axially inward surface contacting the axially outward portion of the bead area of the tire. Each bead portion has a surface contacting a radially inner portion of the rim flange. The surface and the flange initially cease contact and diverge from one another at a location in the cross-section of the tire and rim and in a region of the flange in which a line L1 tangent to the flange surface and passing through the axis forms an angle greater than 0.degree. and less than or equal to 15.degree. with a radial line L2 passing through the point of divergence and perpendicular to the axis. The tire has a steel reinforced radial ply which extends between and wraps about each bead. The ply has an inflection point located radially between a radially outward surface of the bead and a radially outward surface of the rim flange portion.

Abstract: In a pneumatic tire, when a distance between centers in circumferential direction of adjoining grooves at the center of the tread is a pitch and divided into four equal zones, a ratio of maximum negative ratio to minimum negative ratio among negative ratios of these four divided zones in one pitch is not more than 1.22. Thus, the traction performances and ride comfortability are considerably improved.

Abstract: A tire pressure control device of an off-road vehicle is configured for changing tire pressures of vehicle wheels of at least one vehicle axle. Each pneumatic tire has a pressure-controlled wheel valve which is pneumatically connected to a control pressure line and to a supply pressure line. The control pressure lines and the supply pressure lines are pneumatically connected to a compressed air supply device and controlled by an electronic control unit. The actuation of the wheel valves takes place axle by axle via control valves, and the compressed air supply of the vehicle wheels is carried out by side via supply valves.

Abstract: A radial tire (1) for a heavy-duty vehicle of construction plant type, and to reduce the risk of tire tread separation when running over sharp stones, while at the same time ensuring that the crown reinforcement exhibits good resistance to cracking. The tire (1) has a protective reinforcement (50) having three protective layers (51, 52, 53), comprising metal reinforcers that respectively have a diameter (D1, D2, D3) and are distributed at an axial spacing (P1, P2, P3). According to the invention, with Alpha1, Alpha2 and Alpha3 being the angles of the reinforcers of the respective layers (51, 52, 53) with the circumferential direction, the following relationships are satisfied:

15°≤|Alpha1|≤40°

15°≤|Alpha2|≤40°

Alpha1*Alpha2≤0

35°≤|Alpha3|≤75°

As regards the differences between the angles of the reinforcers of the protective layers, the following relationship in terms of absolute values applies:

|(Alpha1−Alpha3)|≥10°

|(Alpha2−Alpha3)|≥10°.

Abstract: The invention provides a rubber composition prepared by mixing, per 100 parts by mass of a rubber component comprising at least 50% by mass of a diene-based rubber, from 20 to 150 parts by mass of a filler, and from 0.05 to 30 parts by mass of a compound A which has a specific guanidine structure and has a functional group reactive with the diene-based rubber. The rubber composition improves both a high elastic modulus and a low tan δ. The invention also provides a pneumatic tire using the rubber composition.

Abstract: A tread part of a tire for a construction vehicle is partitioned in plural by circumferential grooves extending in a tire circumferential direction, and a tread end and a lateral groove. The lateral groove has, on at least one side of a tire equator line, an inflection point where the orientations of concavities and convexities relative to the tire circumferential direction change progressively outward in the tire width direction. The lateral groove extends from the inflection point toward one side in the tire circumferential direction and toward an outer side in the tire width direction, and further extends toward the other side in the tire circumferential direction and toward the outer side in the tire width direction, so as the lateral groove to have a bent groove part that forms a curved convex land portion with respect to the one side in the tire circumferential direction.
