Tire (1) crown reinforcement (3) comprises: protective reinforcement (5) comprising layer (51, 52) comprising reinforcers forming, with the circumferential direction, an angle at least equal to 10°; working reinforcement (6) comprising two layers (61, 62) respectively having axial width (L61, L62) and comprising reinforcers, crossed from one working layer to the next and forming, with the circumferential direction, an angle at most equal to 60°; and additional reinforcement (7), centred axially on an equatorial plane of the tire, comprising layer (71, 72) having axial width (L71, L72) at most equal to 0.9 times the shortest of the axial widths (L61, L62) and comprising reinforcers forming, with the circumferential direction, an angle at most equal to 25°. Additional layer (71, 72) comprises axial discontinuity (81, 82), centred axially on the equatorial plane of the tire, and its width (D1, D2) is at least equal to 0.1 times axial width (L71, L72).
