The invention is directed to a pneumatic vehicle tire having 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 to the lateral tread edges and which are main channels of the tread and which, at least over the major part of the course thereof, have the maximum provided profile depth. The tread has, as profile positives, two rows of transverse ribs which are of encircling form in the circumferential direction and which are separated from one another by respective transverse channels. The tread is of directional configuration, wherein the transverse ribs of one row, and thus the transverse channels running between the transverse ribs, run, with respect to the axial direction, oppositely in relation to the transverse ribs and transverse channels of the other row.

A vehicle tire includes tread blocks with a substantially-horizontal upper/top surface, a first pair of downward-sloping surfaces, a pair of horizontal shoulder surfaces, and a second pair of downward-sloping surfaces. The first pair of downward-sloping surfaces begins and slopes downward and outward from the upper/top surface. Each of the horizontal shoulder surfaces begins and extends outward from one of said first pair of downward-sloping surfaces. The second pair of downward-sloping surfaces begins and slopes downward and outward from the horizontal shoulder surfaces.

A tire 1 includes plural land portions 40 formed on a tread portion 10. The plural land portions 40 are segmented by a circumferential direction groove 30 extending in a tire circumferential direction L and a width direction groove 20, or segmented by an end portion 10E of the tread portion 10 in the tire width direction W and the width direction groove 20. A length of the width direction groove 20 in the tire width direction W is not less than 30% of a length of the tread portion 10 in the tire width direction W. The width direction groove 20 has at least one angled portion 50A/50B configured to be bent toward an opposite direction to a tire rotational direction R on at least one side of a tire equator line CL.

A tread profile is divided into two parts in the axial direction (A) of the tire and has two axially adjacent profile block rows, each of which is formed from profile block elements that are arranged one behind the other over the circumference of the tire and are separated from one another by inclined grooves. The inclined grooves of one profile block row are configured to slope along the axial extent of the inclined grooves through the profile block row, starting from the other profile block row, such that the main direction of extent of the inclined grooves forms an angle of inclination relative to the axial direction (A). The inclined grooves of one profile block row have a direction of inclination which is oriented oppositely to that of the inclined grooves of the other profile block row when seen in the circumferential direction (U).

A tire for a two-wheeled motor vehicle has a tread (2) including: a center region (Cr); a pair of middle regions (Mr) located on both sides of the center region (Cr); and a pair of inner shoulder regions (Sr) located on both sides of the middle regions (Mr). The tread (2) has provided therein: inner tilted grooves (10) having outer ends (10e) provided within the middle regions (Mr); and outer tilted grooves (11) having inner ends (11i) provided within the middle regions (Mr). The groove area ratio of the center region (Cr) is from 34% to 39%, the groove area ratio of the middle regions (Mr) is from 14% to 19%, and the groove area ratio of the inner shoulder regions (Sr) is from 14% to 19%.

A tire provides improved traction performance on farm fields while retaining traveling stability and vibration-damped ride quality on a pavement. The tire has a center region extending in the tire circumferential direction within a range of 15% of the tread width on the left and right sides of the tire axial center of the tread and shoulder regions extending in the tire circumferential direction within a range of 15% of the tread width from the respective edges of the tread toward the tire axial center. And the center-side area Sc, the area of the tread surfaces which are parts within a one-pitch area Spc, is 25% to 40% of the one-pitch area Spc, and the shoulder-side area Ss, the area of the tread surfaces which are parts within a one-pitch area Sps, is 10% to 18% of the one-pitch area Sps, where one-pitch areas Spc and Sps are respectively the areas for one-pitch length of lug blocks adjacent to each other in the tire circumferential direction from the same position in the tire circumferential direction in the center region and the shoulder regions.

A pneumatic tire includes a tread rubber region 5 a belt region 6 including a belt 61 and a contact patch pressure reducing rubber region 7, wherein tread rubber region 5 includes base rubber layer 51 and cap rubber layer 52. The two ends of the tread surface at shoulder lug 55 have first end 551 and a second end (not shown) which is located toward an interior in a tire width direction from first end 551. A contact patch pressure reducing rubber region 7 is disposed at a location between belt 61 and base nibber layer 51. The modulus of contact patch pressure reducing rubber region 7 is lower than the modulus of base rubber layer 51 and is lower than the modulus of cap rubber layer 52.

A tire for running on rough terrain comprises a tread portion 2 bound with an intended tire rotational direction. The tread portion 2 comprises a row of crown blocks 10 and rows of middle blocks 11. The crown blocks 10 and the middle blocks 11 each has an axially-elongated shape. A crown front edge 15 of each of the crown block 10 comprises a most concave portion 18 positioned at the most toe-side thereof in the tire rotational direction and a pair of inclined edges 20 extending from the most concave portion 18 toward axially both sides thereof and toward the heel-side in the tire rotational direction. The inclined edges 20 are each inclined at an angle from 10 to 45 degrees with respect to the tire axial direction. A middle front edge 21 of each of the middle blocks 11 extends axially outwardly and is inclined to the heel-side.
