Tyre comprising a radial carcass reinforcement (60) consisting of threadlike reinforcing elements (61) having an elongation at break EBC, a force at break FBC, placed at a pitch PC and coated with rubber, satisfying the inequality: Formula (I), where FBC is expressed in Newton, RS is the maximum radius (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 core, the pitch PC and the radiuses RS, RE and RT being in metres; each sidewall comprises 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 Formula (II), and EBC ≥ EBA, these parameters being determined on the reinforcing elements before incorporation into the tyre. |
