Abstract: A tire with a radial carcass reinforcement, wherein the ratio of the axial width L of the tread to the maximum axial width S of the tire is strictly greater than 0.85 and the reinforcing elements of at least one layer of the carcass reinforcement are non-wrapped metal cords with saturated layers, at least one inner layer being sheathed with a layer made up of a polymeric composition such as a composition of non-crosslinkable, crosslinkable or crosslinked rubber, preferably based on at least one diene elastomer.

Abstract: Tire tread including a pattern formed by at two ridges of mean width L, which include a plurality of incisions whose traces on the contact surface extend between two points of intersection A and B, the segment AB making an angle with the transverse direction of the tread at most equal to 40°, the tread wherein each incision, of mean width E, includes a succession of incision portions, some of said incision portions having, on any surface parallel to the contact surface in the new condition and located between said surface in the new condition and ? of the maximum depth of the incision, traces that make an average angle ? at most equal to 15° with the longitudinal direction of the tread, said portions having a total length Lt which is at least equal to one-fifth of the ridge width; and in that the incision portions whose traces make an average angle ? are provided on their opposite walls with relief elements of amplitude K designed to cooperate with one another to block relative movements between one incision

Abstract: A tread of thickness E, intended to be used in a tire having a carcass reinforcement surmounted by a crown reinforcement and including on its outer surface a plurality of grooves of depth h, including at least circumferential grooves separated axially by ribs, is provided with at least one internal, circumferential anti-rubber-on-rubber connection element, the outer wall of which, viewed in meridian section, has in part a contour identical to the contour of the wall of the regrooving groove to be created, the point(s) of said wall which are farthest from the axis of rotation being radially distant from the tread surface by a quantity h1 less than the depth h of the grooves, and the point(s) of said wall closest to the axis of rotation being radially distant from the tread surface by the maximum regrooving height H.
