Ronnydobbs,
Are you looking for bigger tires, if so these will work... http://h1071118.hobbyshopnow.com/pro...p?prod=HPI2185 , http://www.horizonhobby.com/Products...odID=PRO105000 , the slicks at the bottom.... http://www.imexrc.com/2.2TIRES_NEW.htm . In fact just about any 2.2" X 2" tire will work...thats the safe size anyhow. Some of the 2.2" rims are offset also and thats good..it will help reduce rub and give you a wider stance (wheel base).
