<p>This invention concerns a tyre of radial type for vehicles designed so as to form a toroidal tube having its own seal, apart from its coupling to the rim. Its structure is closed, not being interrupted by beads, and it has, opposite the tread zone, a convexity forming a continuous circumferential seam with function of self- locking to the rim, which is essentially flat, without a drop centre, and having instead a concave circumferential seat to accommodate the locking seam of the tire. <IMAGE></p> |
