A motor-vehicle wheel

A motor-vehicle wheel (100) comprising a rim (110) having a first bead (115i) and a second bead (115e) defining a well (120) for coupling with a tyre (105), a flange (140) extending towards the inside of the rim (110) in the vicinity of the second bead (115e), the flange (140) being disposed in an outer position when the wheel (100) is fitted on the motor-vehicle, a first hump (125i) and a second hump (125e) projecting from an inner surface of the well (120) in the vicinity of the first bead (115i) and of the second bead (115e), respectively, for cooperating with corresponding beads (130i, 130e) of the tyre (105), the second hump (125e) having a hollow structure. The second hump (125e) includes at least one added element (155) and means (170, 180a, 180b) for fixing the at least one added element (155) to the rim (110), each added element (155) forming at least one cavity (185) with the inner surface of the well (120); alternatively, the second hump (125e) is integral with the rim (110) and includes at least one exposed cavity (205) extending from the interior of the well (120).
