Claim:
A wheel assembly for vehicles, in particular for motor vehicles, which has an axis of symmetry and comprises: a wheel rim defining one or more apertures, and a tyre, including: a tread comprising a plurality of outer grooves and a plurality of radial through-apertures defined in at least some of the outer grooves, two sidewalls, two beads which are attachable to a wheel rim and are made of elastomer material, and at least one tubular reinforcement body for coaxial reinforcement on the said axis, which is surrounded by said tread and extends between said sidewalls, the tubular reinforcement body defining a plurality of tubular body through-apertures, each tubular body through-aperture corresponding with a radial through-aperture and extending into an interior of the tyre; wherein each said radial through-aperture communicates with a corresponding tubular body through-aperture and extends into the interior of the tyre via the corresponding tubular body through-aperture, thereby permitting passage of water therethrough, through the interior of the tyre, and to the exterior of the tyre via the apertures in the wheel rim.
