Abstract

La présente invention a pour objet un pneumatique radial (1) pour véhicule agricole, dont l’indice de charge est au plus égal à 156, dont la sculpture comprend des barrettes d’une hauteur radiale au moins égale à 25 mm et d’une épaisseur au moins égale à 20 mm, comprenant une armature de sommet (3), comprenant 3 couches de travail (31, 32, 33), comprenant chacune des éléments de renforcement en PET de haute ténacité ayant une force de rupture en traction au moins égale à 17.5 daN pour une masse linéique au plus égale à 125 g au km. Les angles ANT1 et ANT3 des éléments de renforcement des couches radialement intérieure et extérieure (31, 33) avec la direction circonférentielle, sont de même orientation et inférieur à 22°. L’angle ANT2 des éléments de renforcement de la couche médiane (32) avec la direction circonférentielle, est d’orientation opposée à ANT1. La valeur absolue de la différence des angles orientés ANT1 et ANT2, est au moins égal à 50°. Figure pour l’ abrégé : Fig. 1
