At least one groove has a plurality of closing devices for reducing the running resonance noise generated by this groove, each closing device comprising at least two flexible blades, a first flexible blade secured to the bottom of the groove and intended to flex around a first axis, and a second flexible blade secured to a lateral wall delimiting the groove and intended to flex around a second axis, the first flexible blade connected to the bottom having a maximum height H.

Tread profile of a vehicle tire with profile elements (1,12,13,14,15,6) separated from one another by grooves (7,8,9,10,23), wherein the profile elements (13,14,1,12) separated by a groove (9,7) are outwardly delimited in the radial direction R by a radially outer surface (16) forming the ground contact area and toward the groove (9,7) respectively by a profile element flank forming a groove wall (17,18), wherein a rubber rib (20,19) extending in the extension direction of the groove (9,7) is respectively formed in the profile element flanks which delimit the groove (9,7) and each form a different groove wall (17,18) of the groove (9,7), wherein the rubber rib (19) formed in one groove wall (17) is formed in a different radial position of the vehicle tire than the rubber rib (20) formed in the other groove wall (18), wherein the two rubber ribs each (19,20) extend over the entire extension length of the profile element flank and wherein each of these two rubber ribs (19,20) respectively extends along its entire extension length from that profile element flank in which it is formed into the groove (9,7) in the direction of the other profile element flank up to at least the middle of the groove width in this radial position of the groove (9,7) and ends there in the groove (9,7) at a distance d2 from the profile element flanks.

A pneumatic tire includes: a plurality of shoulder blocks that are provided in a side portion, defined by a shoulder main groove extending in a tire circumferential direction and a shoulder lateral groove extending in a tire width direction, and disposed side by side in the tire circumferential direction; a rib that is provided in the side portion, and extends in the tire circumferential direction along the shoulder blocks; and a projection that is provided in the side portion, and extends from the rib toward the shoulder blocks.

A pneumatic tire includes a surface and is rotatable about a center axis. The surface of the pneumatic tire includes a ground colored region including a surface of rubber, and an image recognition belt region including a colored region provided in a circumferential direction of the center axis.

The pneumatic tire has main grooves; land portions which are sectioned by the main grooves; paired notches which face to each other as well as being open to a tread surface; the notches being concave portions which are formed in side surfaces of two land portions which are adjacent across the main grooves; tie bars which protrudes at a predetermined height from groove bottoms of the main grooves and connect between the paired notches; and dimples which are provided in the middle in a width direction of the tie bars. The dimples are arranged at least in a notch internal region which is surrounded by wall surfaces of the notches among the tie bars.

A pneumatic tire has a high wet performance with keeping steering stability and wear resistance. Each of the middle land portions (12) is provided with middle sipes (15) and a middle sub-groove (16). Each of the middle sipes (15) has an arc-like shape such that an angle (θ1) with respect to the circumferential direction of the tire gradually increases from its inner end (15i) towards its outer end (15o). A circumferential length (L2) is in a range of from 0.6 to 1.0 times the arrangement pitch (P2) of the middle sipe (15). The middle sub-groove (16) communicates with a shoulder main groove (10), terminates without communicating with a crown main groove (9), and has an arc-like shape having an angle (θ2) that gradually increases from its inner end (16i) to its outer end (16o). A length (L3) of the middle sub-groove (16) is less than the length (L2) of the middle sipe, and the adjacent middle sipe (15) and middle sub-groove (16) overlap one another in the axial direction of the tire.

Pneumatic vehicle tyre having a tread with at least one block row (1, 2, 3) which runs around in the circumferential direction and is separated from further profile positives by at least one circumferential groove (7, 8), and the profile blocks (1a, 2a, 3a) of which are separated from one another in the circumferential direction by transverse grooves (4, 5, 6) and have block edges (10, 11, 12, 11′, 12′) which bound the at least one circumferential groove (7, 8) and transverse grooves (4, 5, 6) and extend at an angle (a) of 0° to 10° with respect to the radial direction. Projections (13, 14) are formed along block edges (10, 11, 12, 11′, 12′), radially inside the block surface forming the tread surface, said projections (13, 14) having a surface (13a, 14a) which runs parallel to the block surface and having an edge extending parallel to the block edge (10, 11, 12, 11′, 12′) at a distance (a2) of 0.3 mm to 1.0 mm, from which edge an end face (13b, 14b), which bounds the projection (13, 14), runs as far as the groove base, said end face (13b, 14b) running at an angle with respect to the radial direction which is up to 7° larger than that of the respective block edge (10, 11, 12, 11′, 12′).
