Abstract:
Tire tread (10) of thickness E, comprising a running surface (12) intended to come into contact with the ground, at least one cutout (20) opening onto the running surface and having a depth P less than the thickness E of the tread. This cutout forms, on the running surface of the tire, when new, two opposing edges, these edges delimiting at least one narrow portion (30) of the cutout, that is to say a portion the mean width LE of which is less than or equal to 1 mm, and at least one wide portion (40) of the cutout, that is to say a portion the mean width LL of which is greater than 1 mm. These wide and narrow portions are positioned such that they alternate, the narrow portion (30) extending over the entire depth P of the cutout, the wide portion (40) extending into the depth of the tread over at least 30% of the depth of the cutout, in which tread the wide portion (40) extends into the depth as far as a depth F less than the depth P of the cutout.
