Tyre comprising a radial carcass reinforcement (60) consisting of threadlike reinforcing elements (61) having an elongation at break EBC and a force at break FBC, placed at a pitch PC and coated with rubber, satisfying the inequality: (I) where FBC is expressed in Newton, RS is the maximum radius (radial distance from the axis of rotation of the tyre) of the carcass, RE is the radius at the tyre maximum axial width, and RT is the inner radius of the bead wire, the pitch PC and the radiuses RS, RE and RT being in metres; each sidewall comprising an additional reinforcement (120) consisting of threadlike reinforcing elements having an elongation at break EBA and a force at break FBA, placed at a pitch PA and coated with rubber, such that (II) and EBC is more than or equal to EBA, these parameters being determined on the reinforcing elements after extraction from the cured tyre.
