摘要： 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.

摘要： A pneumatic tire for vehicle wheels which includes a tread, an annular reinforcing structure, two sidewalls, two beads and having a plurality of slits in the inner and outer surfaces of the sidewalls which may come into contact with other surfaces of the tire or wheel in consequence of the deflation of the tire. The slits are prevailingly oriented in a direction perpendicular to the direction in which takes place the relative slidings between the contact surfaces. Each sidewall has a cross-section along meridian planes of such a shape that its section midline in the meridian plane has a convexity directed towards the tire inside and a flexional rigidity in the meridian plane such that the convexity does not change in direction even under normal operating inflation pressure. The flexional rigidity has a value which is smaller than that of the analogous rigidity of the remaining portions of the sidewall.

摘要： A pneumatic tire and wheel assembly comprising a tire provided with two sidewalls, each of which has at least one hinge, and in which the section midline has a concavity turned towards the outside, characterized in that each bead is encased in a corresponding seat of the rim of said wheel, each seat having the shape of a channel, with a supporting base and two lateral walls, which extends along the whole circumferential development of the rim; at least a part of the axially outermost zone of the bead is radially compressed between the base of the channel and a circumferentially inextensible annular element; and the radial innermost development of the annular element is smaller than the radially outermost development of the axially outer lateral walls of the seats of the rim.
