Tire bead with textile plies

摘要: A tire has a carcass reinforcement ply, anchored within each bead by winding around an annular element whose tensile strength is less than the necessary for wire of conventional same dimension, and assembly at least two textile layers arranged in contact with element, wherein between 3 5 times tension imparted to recommended inflation pressure, elongation break 2 6%, all having 0.5 1 time total strengths being 6 8 reinforcement.
