Tire comprising a radial carcass reinforcement (60) composed of threadlike reinforcing elements (61) having an elongation at break EBC and a force at break FBC, placed at a pitch PC and coated in rubber composition, designed so as to satisfy the relationship: FB C P C ≤ 1.5 · 10 6 · ( R S 2 - R E 2 ) R T , Each sidewall of the tire includes an additional reinforcement (120) composed of threadlike reinforcing elements having an elongation at break EBA and a force at break FBA, placed at a pitch PA and coated in a rubber composition, wherein each of the two additional reinforcements is designed such that FB A P A ≥ 1.3 · FB C P C , and EBC≧EBA, the forces at break FBA and FBC and the elongations at break EBC and EBA being determined on the reinforcing elements before incorporation into the tire. |
