ABSTRACT A tyre is used for both flotation and for propelling a pedal-driven water tricycle or similar recreational vehicle. The tyre is inflatable to provide an inflated structure (10) which has a plurality of protrusions or ribs (13) extending generally transversely across the outermost region of the tyre and across part of the side regions of the tyre. The protrusions or ribs act as paddles to propel the tricycle over water, such as lakes and swimming pools. Alternatively, or additionally, the wheel of the recreational vehicle has a wheel structure formed by a plurality of lamellar spokes (44), which fit into slots (42) located around the hub (40), and which have an outermost region (46) which encircles part of a tyre (49). Alternatively, a wheel of the recreational vehicle may be constructed of a substantially rigid material to have a hub region (52) and a tyre region (51), with fins (53) formed on at least one side of the tyre region (51).
