摘要： A heavy duty pneumatic tire includes a tread surface having, on at least a section thereof, a plurality of circumferential-direction grooves extending along a tread circumferential line and land portions defined either by the circumferential-direction grooves or by the circumferential-direction grooves and tread ground contact edges. The land portions include at least one partitioned land portion in which a plurality of narrow width-direction grooves extending in a tread width direction are provided. A prescribed internal pressure is at least 750 kPa. A depth of the circumferential-direction grooves, represented by H, satisfies a relationship 7 mm≤H≤13 mm. A tread circumferential-direction spacing of the narrow width-direction grooves, represented by W, satisfies a relationship 5 mm≤W≤20 mm.

摘要： Tire including: a tread; a pair of sidewalls extending substantially inward radially from ends of the tread; a pair of beads positioned substantially radially inwardly of the sidewalls; and a clinch portion extending from the sidewalls to the beads. A concave curved surface extends on an outer surface of the clinch portion in a circumferential direction. A convex curved surface formed on a radially outer side end of a rim flange is engageable with the concave curved surface. A ratio R1/R of curvature radius R1 of the concave curved surface to a curvature radius R of the convex curved surface of the rim flange satisfies 1.7≤R1/R≤2.5. The curvature radii R1 and R of the concave and convex curved surfaces, respectively, are each a radius of curvature of an arc on a cross-section taken along a plane including a tire center axis.

摘要： A pneumatic vehicle tire of a radial type of construction is for heavy trucks and has a four-ply belt (3). Each belt ply (7, 8, 9, 10) contains steel cords as reinforcing elements which run parallel to one another in each belt ply. Not only are the angles (β, γ) that the steel cords in the second and third belt plies (8, 9) form with the circumferential direction (A-A) approximately equal, but also the angles (α, δ) that the steel cords in the first and fourth belt plies (7, 10) form with the circumferential direction (A-A) are likewise approximately equal.

摘要： In a tire 2 according to the present invention, an outer surface 52 of a crown rib 48e and an outer surface 54 of a shoulder rib 48s form a part of a tread surface 28. On a cross-section of the tire 2 along a plane that includes a rotation axis of the tire 2, an outline of the outer surface 52 of the crown rib 48e is represented as a first arc. A center of a circle to which the first arc belongs is disposed on the equator plane. An outline of the outer surface 54 of the shoulder rib 48s is represented as a second arc. A ratio of a distance from a center of a chord of the second arc to the second arc relative to a length of the chord of the second arc is not less than 0.03 and not greater than 0.05.

摘要： A pneumatic vehicle tire for commercial vehicles is provided wherein the wet traction properties are improved with simultaneously good rolling resistance properties. At least 120 transverse grooves are arranged in each of the central profile ribs over the entire circumference of the tire. The width (B1) of the transverse grooves in the central profile ribs is maximally 1.5 mm at a distance of 3.5 mm from the profile surface, and the width of each inner circumferential groove is maximally 4 mm at a distance of 3.5 mm from the profile surface.
