Abstract
A tread for passenger-vehicle tire having radially on the outside a running surface and comprising a plurality of elements, at least certain of these elements being provided with at least one incision delimited by two opposite faces, this incision consisting of a succession of thin sections and of thick sections placed in an alternating manner, the thin sections being inclined at an angle A equal to no more than 40 degrees, this angle being measured relative to a direction perpendicular to the running surface of the tread and passing through the points of the incision on the running surface of the tread, the thick sections forming an angle B of between 60 degrees and 120 degrees with a direction perpendicular to the running surface of the tread, and the thin sections having a width e less than the width E of the thick sections, the width of the thin sections being such that, when they go through the contact patch, the walls delimiting said thin sections are in contact, and the width of the thick sections being such that, when they go through the contact patch, the walls delimiting the thick sections are not in contact.
