Zusammenfassung:	A support assembly for a surface treating appliance includes a roller having one or more tires, wherein the one or more tires are fused to the roller. The roller can include a polymer such as polypropylene and may also include a glass filled impact modified copolymer such as a 20% glass filed impact modified copolymer. The tires can include a thermoplastic elastomer such as a modified polymer including a mixture of polypropylene and an ethylene propylene diene monomer. The thermoplastic elastomer may have a hardness of from 55 to 95 Duro measured on the A scale, more specifically from 70 to 79 Duro on the A scale or from 80 to 95 Duro on the A scale.
