There used to be only one company that made pre-mounted foams for the supers, but anyway the quality of the rims and tires were terrible. I used ellegi donuts mounted onto hpi /kyosho rims. That seemed to be the only ticket. There used to be a full heat with everyone running nothing less. There's alot of labor involved in shaving the rims down and mounting the foams so the price of the tires are high unless you do it yourself. It's usually around $65.-$75 for a complete set of four. Have you ever ran foams on your super?
