A wheel construction includes a wheel rim which in use, receives a tyre, the rim being circular and having axially inner and outer portions each of which provides a flange which in use provides a seat for a bead of the tyre, and the wheel construction including a mid-portion between the inner and outer portions, and side parts, connecting the mid and outer portions, the mid-portion including a circumferential well where the radius of the wheel rim is a minimum, at least one of the side parts including a plurality of curved regions, the plurality of curved regions each being immediately adjacent to each other whereby the side part is continuously undulate. Each curved region provides at least a further two circumferential wells. For each adjacent two curved regions, there is an effective angle between a plane normal to the axis of the wheel and a line struck tangentially at a point of inflection between the two curved regions at a tyre side of the rim, of between 25° and 45°.
