A hub-bearing unit () has a rotatable outer race () fixable to a wheel and an inner stationary hub () forming a passage () for pressurized air coming from a source of pressurized air mounted onboard of a vehicle. Tightly fitted on the axially outer side of the unit () is a cylindrical cover () defining with the unit () an airtight chamber () communicating with the passage (). The cover () has a through bore () for establishing air communication between the chamber () and a tube (A, B) for conveying pressurized air to the tire. The cover has an outer wall () with a cylindrical portion () axially protruding beyond the hub-bearing unit () so as to provide a cylindrical surface for centering the wheel of the vehicle.
