Well I'm just about done installing my 9lb powerdyne supercharger kit(just need to mount new MAF) and I'm looking into some wider rims and tires. Despite everyone having cobra rims, I'm going to get a pair myself...17X8 Fronts and 17X9 Rears. How wide of a tire will I need to get some decent traction at the track? I'm thinking 275's will do the job or is that a little overkill? Maybe 255's? Am I better off just getting 255's for everyday driving and some slicks for at the track? Also, can someone recommend me some tires that will be sticky at the track yet good for a daily driver?
