The present invention relates to a wheel arrangement for a rail vehicle (101), in particular, a light rail vehicle, comprising a wheel unit (107) and a support unit (108), wherein the wheel unit (107) defines an axis of rotation (107.1) of the wheel unit (107). The support unit (108) is configured to be connected to a rail vehicle structure (104) of the rail vehicle (101) defining a vehicle longitudinal direction, a vehicle transverse direction and a vehicle height direction. The support unit (108) is configured to connect the wheel unit (107) to the rail vehicle structure (104) such that the wheel unit (107) is rotatable about the axis of rotation (107.1). The support unit (108) further comprises a primary suspension unit (105) configured to provide resilient support of the rail vehicle structure (104) on the wheel unit (107) at least in the vehicle height direction. The primary suspension unit (105) has a primary suspension transverse rigidity in a direction parallel to the axis of rotation (107.1), wherein a distribution of the primary suspension transverse rigidity across the primary suspension unit (105), in particular, in a static state of the rail vehicle (101) on a straight level track under a nominal load, defines a tilt axis (107.2) of the wheel unit (107) parallel to the vehicle longitudinal direction. The distribution of the primary suspension transverse rigidity is such that, in the vehicle height direction, the tilt axis (107.2) is located below the axis of rotation (107.1).
