Tyre for a vehicle comprising two thin and lightened working layers (41, 42), comprising metal reinforcing elements (41, 42) having a linear breaking strength Rct at least equal to 300 daN/cm and at most equal to 400 daN/cm, and a single carcass layer (6) radially inside the working layers (41, 42), said carcass layer (6) comprises textile reinforcing elements having a stretch at break Acc at least equal to 15%, if the tyre has a nominal width at least equal to 135 mm, the linear breaking strength Rcc of the carcass layer (6) is at least equal to 0.55 times the linear breaking strength Rct of each working layer (41, 42), and if the tyre has a nominal width at least equal to 245 mm, the linear breaking strength Rcc of the carcass layer (6) is at least equal to 0.65 times the linear breaking strength Rct of each working layer (41, 42).
