Embodiment Construction

[0033] The invention is not limited to the presented embodiments and variants, and other embodiments and variants will become apparent to those skilled in the art.

[0034] figure 1 Tire 1 is partially shown. The tire 1 comprises a tread 10 and two shoulder regions 11A, 11B. As previously mentioned, tread 10 has a tread surface. The tread surface gathers all the points where the tread comes into contact with the road surface when the tire 1 is driven under normal running conditions of the tire 1 . The two shoulder regions 11A, 11B are not intended to come into contact with the road surface. These two shoulder regions 11A, 11B delimit two respective edges 12A, 12B of the tread. In practice, the edges 12A, 12B of the tread 10 can be determined by the indentations on the support of a tire pre-colored and mounted on a testing machine suitable to reproduce the normal running conditions of this tire 1 . The two shoulder regions 11A, 11B pass through their respective sidewalls (...

Abstract

The invention relates to a tyre comprising a tread (10) defined by two edges (12A, 12B), the tread (10) comprising a circumferential groove (14) and a plurality of transverse grooves (20A, 20B). Each transverse groove (20A, 20B) extends from one of the edges (12A, 12B) of the tread (10) to a first end (22) of the transverse groove (20A, 20B). At least one transverse groove (20A) of the plurality of transverse grooves (20A, 20B) comprises a bottom which meets the first end (22), thus forming a first inclined wall (26). The tread (10) comprises a transverse incision (30) arranged between two transverse grooves (20A, 20B), the transverse incision (30) extending from the circumferential groove (14) to a second end (32) of the transverse incision (30). The transverse incision (30) comprises a bottom which meets the second end (32), thus forming a second inclined wall (36), the second inclined wall (36) intersecting the first inclined wall (26) in a radial cross-section plane (A-A) and in a projection of the inclined walls (26, 36) in said radial cross-section plane (AA).

Description

technical field [0001] The present invention relates to tires for motor vehicles, and more particularly to tires with better controlled wear during operation. The invention is not limited to a particular type of vehicle, it is applicable to tires of motor vehicles belonging to different types of motor vehicle lists (eg passenger vehicles, trucks, heavy vehicles, agricultural vehicles, construction site vehicles or two-wheeled vehicles, etc.). Background technique [0002] In a known manner, tires intended to be mounted to motor vehicles have a tread. This tread comprises a tread surface and two edges delimiting said tread surface. The tread surface corresponds to all the points at which the tread comes into contact with a road surface when a tire inflated to its reference pressure and compressed by a reference load runs on the road. The reference inflation pressure and the reference load are defined in the tire service conditions specified in particular by the E.T.R.T.O. s...
