It is an object to provide a tire having an excellent balance of wet grip performance and chipping resistance. The tire is a tire comprising a tread, wherein the tread has a lateral groove neither of both ends of which opens into circumferential grooves, wherein a predetermined rubber component, a predetermined filler, and a silane coupling agent are compounded in a rubber layer of a tread surface, wherein a brittleness temperature of the rubber component and a ratio of a groove depth at the deepest part of the groove bottom of the lateral groove neither of both ends of which opens into the circumferential grooves to a thickness of the entire tread are made to lie in predetermined ranges.

A pneumatic tire includes a narrow groove disposed on a vehicle outer side of a tire equator in the tread portion extending in the tire circumferential direction, wherein the narrow groove has a groove width of from 1 mm to 6 mm; and a plurality of lug grooves disposed in the tread portion that intersect with the narrow groove and include terminating ends on opposite sides, wherein the plurality of lug grooves are each curved toward one side in the tire circumferential direction.

Provided is a pneumatic tire. Distances from a tire equator of the first to third main grooves and narrow groove respectively are from 5% to 20%, 20% to 35%, 55% to 70%, and 40% to 60% of a tire ground contact half-width TL/2. First lug grooves reach a ground contact edge on a vehicle inner side and terminate within a first rib, second lug grooves communicate with the third main groove and terminate in a second rib, third lug grooves communicate with the second main groove and terminate within a third rib, fourth lug grooves communicate with the first main groove and terminate within a fourth rib, fifth lug grooves intersect the narrow groove and terminate within the fourth rib and a fifth rib, and sixth lug grooves reach a ground contact edge on the vehicle outer side and terminate within the fifth rib.

A pneumatic tire comprises a tread portion provided on each side of the tire equator with a middle land portion defined between a shoulder main groove and a crown main groove each extending continuously in the tire circumferential direction. The middle land portion is provided with axially inside middle lug grooves and axially outside middle lug grooves arranged alternately in the tire circumferential direction. The axially inside middle lug groove is connected to the crown main groove at an angle θ1 of from 20 to 45 degrees with respect to the tire circumferential direction and has an axially inner opened end and an axially outer closed end. The outside middle lug grooves is connected to the shoulder main groove at an angle θ2 of from 60 to 80 degrees with respect to the tire circumferential direction and has an axially outer open end and an axially inner closed end. The tread portion may be provided with a shoulder land portion comprising circumferential sipes, axial grooves terminating at the circumferential sipes, and a circumferentially continuous rib.

The invention relates to vehicle tires for utility vehicles, comprising a belt (9) and a tread profile that extends in the axial direction A of the vehicle tire between two tire shoulders, in each of which a profiled shoulder strip (19) is formed that extends over the circumference of the vehicle tire. The profiled shoulder strip is delimited in the axial direction A towards the equatorial plane Ä of the tire by a groove (20), which extends over the circumference of the vehicle tire, and on the profiled strip face facing away from the equatorial plane Ä by a respective surface of the tire lateral wall (2), which forms the profiled shoulder strip (19) flank facing away from the equatorial plane Ä. The tread profile is delimited by a surface which forms the road contact surface on the sectional planes containing the tire axis, said surface forming a surface contour line K which is curved towards the tire between the profiled shoulder strips (19). In at least one profiled shoulder strip (19), the surface which forms the road contact surface is formed as the extension of the curved surface contour line K into the profiled shoulder strip (19) in an axial first extension section (21) of the width a, said extension section adjoining the circumferential groove (20), and the radial position of the surface which forms the road contact surface constantly decreases outwards along the axial extension in a second extension section (22) of the width c, said extension section adjoining the first extension section (21) and extending to the surface of the tire lateral wall. The surface which forms the road contact surface is formed by a first sub-portion (23), which extends to a point P, and a second sub-portion (24), which extends from the point P to the surface of the tire lateral wall (2), in the second extension section (22) such that the surface which forms the road contact surface has a concave contour progression in the first sub-portion (23) and a convex contour progression in the second sub-portion (24) with a turning point of the contour progression in the point P, said point P being arranged outside of the belt (9) in the axial direction A.
