Tire comprising a crown reinforcement radially inside the tread, and a carcass reinforcement radially inside the crown reinforcement. The crown reinforcement comprises radially from the outside towards the inside: a protective reinforcement comprising two protective layers comprising elastic metal reinforcers which are parallel to one another within each layer and crossed from one layer to the next, forming respective angles A1 and A2 with the circumferential direction, a working reinforcement comprising two working layers comprising inelastic metal reinforcers, parallel to one another within each layer and crossed from one layer to the next, forming respective angles B1 and B2 with the circumferential direction. Angle B1 is non-zero and at most equal to 35° and angle B2 is at least equal to 70° and strictly less than 90°. |
