The pneumatic tyre, for fitting to vehicle wheel rims, has a contour (1) of the tyre carcass (13) divided by a central wall (2) round the periphery, to form twin compartments for the compressed air. The wall (2) is part of the tread (3), and has claws (4) at the bottom end with two flanges (5) to grip a part (12a) of the wheel rim (12). |
