A method of manufacturing a vehicle wheel tooth, the method comprising:
- casting a base for the tooth by pouring a first molten metal or metal alloy into a first mold which defines the desired configuration of a base for the tooth;

- pouring a second molten metal or metal alloy into the second mold to cast the cap directly on to the base,
- wherein the base is provided with formations which receive the second molten metal or metal alloy during the casting step such that the cap is keyed into the base.
