The combination of a toothed pulley and a toothed belt and method of making the same are provided. The toothed belt has teeth that serially mesh with cavities of the pulley that are respectively disposed between adjacent teeth thereof and that respectively have bottoms. Each belt tooth has a longitudinal cross-sectional configuration that defines a pair of spaced side faces that respectively have free end portions that are remote from adjacent roots thereof and that are spaced apart from each other by a bottom face of the tooth, each bottom face having a center. The teeth of the pulley and the belt are so constructed and arranged that each belt tooth would have the pair of spaced apart free end portions thereof compressed radially outwardly and inwardly toward each other by the respective adjacent pulley teeth while the bottom face thereof has its center spaced from the bottom of the cavity between those respective adjacent pulley teeth if that belt tooth is fully received in the cavity between those respective adjacent pulley teeth and those respective adjacent pulley teeth are just making contact with the land areas of the belt on each side of that belt tooth while being spaced from the respective roots of that belt tooth.
