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 Fahrzeugluftreifen mit einem Laufstreifen mit schulterseitigen Profilblöcken (4), welche durch Schrägrillen (1) getrennt und laufstreifeninnenseitig jeweils von einer zur Umfangsrichtung gegensinnig zu den Schrägrillen (1) geneigt verlaufenden Rille (3) begrenzt sind, wobei die Rille (3) eine in ihrer maximalen Tiefe (tR) verlaufende, in die Schrägrillen (1) einmündende, sich in Draufsicht schräg durch die Rille (3) hindurcherstreckende Rillengrundrille (13) aufweist.
Die Rillenwände (11, 12) der Rille (3) setzen sich, im Querschnitt betrachtet, jeweils aus einer radial äußeren Flankenfläche (11a, 12a) und einer an diese anschließenden, zur Rillengrundrille (13) verlaufenden und zu dieser abfallenden, zur radialen Richtung unter einem Winkel (ε, η) verlaufenden Schrägfläche (11b, 12b) zusammen, wobei der Winkel (ε), unter welchem die Schrägfläche (11b) der einen Rillenwand (11) verläuft, und der Winkel (η), unter welchem die Schrägfläche (12b) der anderen Rillenwand (12) verläuft, ihre Größen über die Längserstreckung der Rille (3) fortlaufend sowie zueinander entgegengesetzt ändern.
