The invention relates to a tyre in which the crown reinforcement comprises at least three plies of reinforcing elements. According to the invention, there are: at least a first profile P1 the axially outer end of which lies a shorter distance from the equatorial plane of the tyre than the distance separating said plane from the end of a second ply, said profile P1 being radially separated from the radially outer calendering C1 of a first ply by a second profile made of rubber compound G1, at least one third profile P2 the axially outer end of which lies a shorter distance from the equatorial plane of the tyre than the distance separating said plane from the end of a third ply, said profile P2 being radially separated from the radially inner calendering C2 of said first ply by a fourth profile of rubber compound G2, said profiles of rubber compound P1, P2 and G1, G2 and said calendering C1, C2 having respective secant tensile elastic moduluses at 10% of elongation of MP1, MP2, MG1, MG2, MC1, MC2 such that MC1 >= MG1 > MP1 and MC2 >= MG2 > MP2.

L'invention concerne un pneumatique dont l'armature de sommet comprend au moins trois nappes d'éléments de renforcement. Selon l'invention, au moins un premier profilé P1 dont l'extrémité axialement extérieure est située à une distance du plan équatorial du pneumatique inférieure à la distance séparant dudit plan l'extrémité d'une deuxième nappe, ledit profilé P1 étant radialement séparé du calandrage radialement extérieur C1 d'une première nappe par un deuxième profilé de mélange caoutchouteux G1, au moins un troisième profilé P2 dont l'extrémité axialement extérieure est située à une distance du plan équatorial du pneumatique inférieure à la distance séparant dudit plan l'extrémité d'une troisième nappe, ledit profilé P2 étant radialement séparé du calandrage radialement intérieur C2 de ladite première nappe par un quatrième profilé de mélange caoutchouteux G2, lesdits profilés de mélange caoutchouteux P1, P2 et G1, G2 et lesdits calandrages C1, C2 ayant respectivement des modules sécants d'élasticité sous tension à 10 % d'allongement MP1, MP2, MG1, MG2, MC1, MC2 de sorte que MC1 >= MG1 > MP1 et MC2 >= MG2 > MP2.
