Tyre for a pram

The tire (1) has an outwardly facing bearing surface and an inner lateral surface which is aligned to the rotational axis of the tire. A portion forms the inner lateral surface and is formed from a material. Another portion forms a part of the bearing surface and is formed from another material. The former material is formed softer than the latter material. The radius of curvature of the bearing surface carries 30 millimeter to 80 millimeter, particularly 35 millimeter to 60 millimeter. An independent claim is included for a wheel with a wheel rim.
