Abstract
The tread has a wearable thickness of material EMU and has raised elements delimited by grooves. Each solid part has a contact face and a cavity with a depth greater than 50% of the wearable thickness. Each cavity opens onto the contact face when new and is delimited by a wall surface and a bottom surface. Each wall surface deliminates a cavity that intersects the contact face along a corner edge contour that has a geometry that has a major axis which is at least 1.5 times the length of a minor axis when new. For any tread surface down to a predefined wear level, the level is at most 30% of the wearable thickness of material EMU, and the angle between the major axis and the circumferential direction is between 0 and 40 degrees. After the wear level, the angle is greater than 40 degrees.
