Abstract
A rail vehicle wheel comprises a wheel center (1), a flanged tire (2), a rubber ring (3) between the wheel center and the tire, and a pressure ring (4). The rubber ring consists of an annular, axial body (3') and at each side thereof a flange (3"), which forms an angle of for example 60.degree. with the wheel axis.
