Abstract

Cette enveloppe de pneumatique présente une bande de roulement comportant des blocs 3.1, 3.1' allongés en relief munis d'une ou de plusieurs découpures et délimités par des segments de rainure 3.2, 3.2' essentiellement rectilignes, non alignés, qui communiquent entre eux en formant un réseau croisé de rainures d'orientation transversale et oblique par rapport à la direction circonférentielle du pneumatique en traversant de part en part la bande de roulement pour déboucher dans la zone des épaules sur les côtés latéraux de l'aire de contact du pneumatique avec le sol, les blocs 3.1 en relief à grand axe transversal ont essentiellement la forme d'un solide prismatique dont le contour en section transversale s'inscrit dans un losange tronqué, les blocs en relief 3.1' des zones des épaules se différenciant essentiellement des blocs en relief de la couronne annulaire du sommet par leurs plus grandes dimensions en section transversale et par le fait que leur hauteur diminue progressivement en direction des flancs du pneumatique sensiblement à partir de leur diagonale parallèle à la direction circonférentielle du pneumatique.This tire casing has a tread comprising blocks 3.1, 3.1 'elongated in relief provided with one or more cutouts and delimited by groove segments 3.2, 3.2' which are essentially rectilinear, not aligned, which communicate with each other forming a crossed network of transverse and oblique orientation grooves with respect to the circumferential direction of the tire, crossing right through the tread to emerge in the shoulder area on the lateral sides of the contact area of the tire with the tire ground, the 3.1 blocks in relief with a large transverse axis essentially have the shape of a prismatic solid whose cross-sectional contour is inscribed in a truncated rhombus, the blocks in relief 3.1 'of the shoulder areas differing essentially from the blocks in relief of the annular crown of the apex by their larger dimensions in cross section and by the fact that their height gradually decreases e n direction of the sidewalls of the tire substantially from their diagonal parallel to the circumferential direction of the tire.
