发明名称 LIGHTWEIGHT TYRE COMPRISING A CROWN LAYER RADIALLY ON THE INSIDE OF THE CARCASS STRUCTURE
摘要 <p>A tire comprising at least one carcass-type reinforcing structure and comprising a crown reinforcing structure having at least one working layer. At least one working layer is radially on the inside of at least one carcass layer, in the sidewalls, the tire comprises at least two carcass reinforcing layer portions extending over a radial distance at least equal to 50% of the radial distance between an end of a shoulder and the radially inner end of the radially innermost circumferential reinforcing element, at least in the equatorial plane, the reinforcing elements of the carcass reinforcement make an angle less than 80°, and the reinforcing elements of the working layer cross with the reinforcing elements of the carcass-type reinforcing structure by an angle greater than 40°, when the tire comprises at least two working layers radially on the inside of at least one carcass layer, the reinforcing elements of the at least two working layers being crossed by an angle of at most 5° and when the tire comprises at least one working layer radially on the outside of the carcass-type reinforcing structure, the reinforcing elements of the at least one working layer crossing with the reinforcing elements of at least one working layer radially on the inside of at least one carcass layer by an angle of at least 30°.</p>
