Abstract

Pneumatique pour roue de véhicules ayant une bande de roulement dont la surface radialement extérieure possède un dessin qui comprend plusieurs rainures circonférentielles en zig-zag délimitant des cordons de même forme dont l'un au moins présente plusieurs entailles transversales qui s'étendent d'une rainure à l'autre. Ce pneumatique est caractérisé en ce que les entailles sont composées d'une suite de trois segments contigus dont deux sont des segments latéraux situés à proximité des bords du cordon et qui débouchent dans les rainures correspondantes. L'invention s'applique aux pneumatiques de grandes dimensions destinés aux véhicules pour transports lourds.Tire for vehicle wheel having a tread whose radially outer surface has a pattern which comprises several circumferential zig-zag grooves delimiting beads of the same shape, at least one of which has several transverse notches which extend from one side to the other. groove to another. This tire is characterized in that the notches are composed of a series of three contiguous segments, two of which are lateral segments located near the edges of the bead and which open into the corresponding grooves. The invention applies to tires of large dimensions intended for vehicles for heavy transport.
