摘要： According to aspects of the invention, a tire for a vehicle comprising a tread is provided. The tread comprises a set of consecutive blocks arranged along a circumference of the tire; and a plurality of first grooves arranged over the circumference of the tire, wherein each of the plurality of first grooves is arranged between two blocks of the set of consecutive blocks. Each of the set of consecutive blocks comprises a leading edge and a trailing edge. Each leading and trailing edge comprises a first portion arranged at a shoulder region of the tire, a second portion arranged at a position axial inward to the first portion, and a third portion arranged at a position axial inward to the second portion. Each of the set of consecutive blocks further comprises a first chamfer arranged at least at one of the leading and trailing edge. The first chamfer has a first average width in the first portion, a second average width in the second portion and a third average width in the third portion. The first average width projected onto a circumferential direction of the tire corresponds to a first projected average width, the second average width projected onto the circumferential direction of the tire corresponds to a second projected average width, and the third average width projected onto the circumferential direction of the tire corresponds to a third projected average width. At least two of the first projected average width, the second projected average width and the third projected average width are substantially equal.

摘要： Die Erfindung betrifft einen Nutzfahrzeugreifen mit einem laufrichtungsgebunden ausgeführten Laufstreifen (1) mit einem zentralen Laufstreifenbereich (3), welcher durch Teilungseinschnitte (8) mitbegrenzte, blockartige Profilstrukturen (3a) aufweist, welche jeweils mit weiteren Einschnitten (10) versehen sind.
Der zentrale Laufstreifenbereich (3) ist mit über seine maximale Breite (bb) V-förmig zueinander verlaufenden Schrägrillen (7) versehen, wobei die Teilungseinschnitte (8) zwischen V-förmig zueinander verlaufenden Schrägrillen (7) verlaufen und vom Ende jeder Schrägrille (7) jeweils ein Teilungseinschnitt (8) ausgeht, wobei die weiteren Einschnitte (10) die jeweilige blockartige Profilstrukturen (3a) durchqueren, bezüglich der Umfangsrichtung gegensinnig zu den an die blockartige Profilstruktur (3a) angrenzenden Schrägrillen (7) geneigt sind und zur axialen Richtung unter Winkeln (ε) verlaufen, welche ausgehend von jenem weiteren Einschnitt (10), welcher gegen die Abrollrichtung (R) auf den entsprechenden Teilungseinschnitt (8) folgt, von Einschnitt (10) zu Einschnitt (10) stufenweise zunehmen.

摘要： A tire 2 includes a tread 4, a belt 16, and a band 18. The belt 16 includes belt cords 44. The band 18 includes band cords 60. The band 18 is composed of a band strip 58. The band strip 58 is a cord array in which the band cords 60 are arranged. A zone from a first end to a second end of the belt 16 is a control zone. Residual tension of the band cords 60 in the control zone is not less than 15.0 N. The control zone includes a crown zone and a pair of shoulder zones. Residual tension of the band cords 60 in the crown zone is higher than residual tension of the band cords 60 in each shoulder zone. A shape index of a reference ground-contact surface of the tire 2 is not less than 1.00 and not greater than 1.30.

摘要： A motorcycle tire set S includes a front wheel tire S1 and a rear wheel tire S2 each provided with a plurality of inclined grooves 3. Each inclined groove 3 includes a first portion 11 extending in a crown region Cr, a second portion 12 extending in a shoulder region Sh, and a third portion 13 connecting the first portion 11 and the second portion 12. The third portion 13 has a smaller groove width than the first portion 11 and the second portion 12. The first portion 11, the second portion 12, and the third portion 13 are inclined in the same direction with respect to a tire circumferential direction. Each inclined groove 3 of the rear wheel tire S2 comes into contact with the ground from the first portion 11 toward the third portion 13 based on a tire rotation direction R.
