<p>A pneumatic wheel for vehicles including a tire provided with a tread, two sidewalls and two beads and a rim with two seats, one for each bead. Each seat has the shape of a circumferential channel having an opening for the introduction of each bead in its seat. The width of the opening is smaller than the maximum width of the seat. Each bead has in cross-section a profile at least partially equal to that of the corresponding seat of the rim and is substantially indeformable. The cross-section of the bead is smaller than the cross-section of the seat. Each bead is locked in its seat by an element having a modulus of resistance to compression of the same order of magnitude as that of the compound forming the beads and which makes coincident the partially equal profiles. The tire is anchored to the rim by introducing the element into the seat on the rim after the introduction of the bead so as to press the surface of the bead against the surface of the corresponding seat.</p> |
