Tire (1) having a crown reinforcement (4) of at least two layers of crossing non-stretch cables, and a tread (5) connected to the tire beads by side walls, has the thickness of its crown block reducing towards its shoulders (6) and at least one circumferential crown reinforcing layer with a preferable width greater than 65 per cent of the axial width of the tread. Tire (1) having a crown reinforcement (4) of at least two layers of crossing non-stretch cables, and a tread (5) connected to the tire beads by side walls, has the thickness of its crown block reducing towards its shoulders (6) and at least one circumferential crown reinforcing layer with a preferable width greater than 65 per cent of the axial width of the tread. The tire has an aspect ratio (H/S) that is preferably below 0.5:1, where H is the height of the tire above the wheel rim and S is its maximum width. In addition the widest (41) of the crown reinforcing layers is located radially inside the other layers (42, 43, 44). |
