Abstract

The subject of the present invention is a tyre, intended to be fitted to a construction plant vehicle, and the invention relates more particularly to the protective reinforcement of said tyre. In order to increase the resistance to attack of its protective reinforcement, when running over sharp stones, the reinforcers of each protective layer (51) are two-dimensional elements (511) each having an individual cross section Se and each one separated from the next, each two-dimensional element (511) is inscribed inside a minimum disc having centre O and diameter D which is both at least equal to 0.1 times L, expressed in mm, and at least equal to 30 mm, and the centres O of the minimum discs circumscribed around the two-dimensional elements (511) are positioned at the vertices of identical regular polygons so that the two-dimensional elements constitute a regular blocked pattern.
