Abstract
A tire (10) comprises a tread comprising a circumferential rib (28, 30, 32) and first and second cuts. The first cut has a length along the axial direction (Y) that is different from the length along the axial direction (Y) of the second cut (40). An angle formed by the direction of the first portion and the direction of the second portion of the first cut (38) is substantially equal to an angle formed by the direction of the first portion and the direction of the second portion of the second cut (40). An angle formed by the direction of the second portion and the direction of the third portion of the first cut (38) is substantially equal to an angle formed by the direction of the second portion and the direction of the third portion of the second cut (40).

A pair of a first tire and a second tire,
- the first tire comprising a first tread comprising cuts comprising a first cut made in a first circumferential rib delimited by first and second circumferential cuts axially adjacent to the first circumferential rib,
- the second tire comprising a second tread comprising cuts comprising a second cut made in a second circumferential rib delimited by first and second circumferential cuts axially adjacent to the second circumferential rib,
- the cuts made in each first and second circumferential rib opening into each of the first and second circumferential cuts delimiting the first or second circumferential rib respectively in first and second opening zones, an azimuth of a point of the first opening zone of a cut made in the first or second circumferential rib being substantially aligned circumferentially with an azimuth of a point of the second opening zone of another cut made in the first or second circumferential rib,
- each first and second cut comprising first, second and third portions, the first portion and the second portion of each first and second cut being joined directly together by a first inflection zone, the second portion and the third portion of each first and second cut being joined directly together by a second inflection zone, the second portion of each first and second cut being arranged axially between the first and third portions respectively of each first and second cut,
- a mean direction of the first portion of each first and second cut not being parallel to a mean direction of the second portion respectively of each first and second cut,
- a mean direction of the third portion of each first and second cut not being parallel to the mean direction of the second portion respectively of each first and second cut,
- the first cut having a length along an axial direction that is different from a length along the axial direction of the second cut,
- an angle formed by the mean direction of the first portion and the mean direction of the second portion of the first cut being substantially equal to an angle formed by the mean direction of the first portion and the mean direction of the second portion of the second cut,
- an angle formed by the mean direction of the second portion and the mean direction of the third portion of the first cut being substantially equal to an angle formed by the mean direction of the second portion and the mean direction of the third portion of the second cut,
- a length of the second portion of the first cut being substantially equal to a length of the second portion of the second cut,
- the second portion of the first cut extending along the mean direction that is not parallel to the mean direction along which the second portion of the second cut extends, and/or a length of the first portion of the first cut being different from a length of the first portion of the second cut and/or a length of the third portion of the first cut being different from a length of the third portion of the second cut.
A tire comprising a tread comprising cuts comprising:

- a second cut made in a second circumferential rib delimited by first and second circumferential cuts axially adjacent to the second circumferential rib,
- the cuts made in each first and second circumferential rib opening into each of the first and second circumferential cuts delimiting the first or second circumferential rib respectively in first and second opening zones, an azimuth of a point of the first opening zone of a cut made in the first or second circumferential rib being substantially aligned circumferentially with an azimuth of a point of the second opening zone of another cut made in the first or second circumferential rib,
- each first and second cut comprising first, second and third portions, the first portion and the second portion of each first and second cut being joined directly together by a first inflection zone, the second portion and the third portion of each first and second cut being joined directly together by a second inflection zone, the second portion of each first and second cut being arranged axially between the first and third portions respectively of each first and second cut,
- a mean direction of the first portion of each first and second cut not being parallel to a mean direction of the second portion respectively of each first and second cut,
- a mean direction of the third portion of each first and second cut not being parallel to the mean direction of the second portion respectively of each first and second cut,
- the first cut having a length along an axial direction that is different from a length along the axial direction of the second cut,
- an angle formed by the mean direction of the first portion and the mean direction of the second portion of the first cut being substantially equal to an angle formed by the mean direction of the first portion and the mean direction of the second portion of the second cut,
- an angle formed by the mean direction of the second portion and the mean direction of the third portion of the first cut being substantially equal to an angle formed by the mean direction of the second portion and the mean direction of the third portion of the second cut,
- a length of the second portion of the first cut being substantially equal to a length of the second portion of the second cut,
- the second portion of the first cut extending along the mean direction that is not parallel to the mean direction along which the second portion of the second cut extends, and/or a length of the first portion of the first cut being different from a length of the first portion of the second cut and/or a length of the third portion of the first cut being different from a length of the third portion of the second cut.
