I really know nothing about tire sizing other than the bolt pattern. I have some extra cash not going to motor parts right now, and I was thinking that maybe some fender flares and wide tires would be better than horsepower.

Step1: So anyways, I figure that the fender flares add 3 inches, and then a few more bills gets me some wheel adapters so I can run 5x4.5" bolt pattern.

Step2: I was lookin at this wheel

Question: What is rear spacing, and what would be a good size combo that won't stick out but get the max out of the flares. What size (not diameter, but width)?

And to a lesser extent, does anyone know a good combo tire for track and road racing or would it be best to buy 2 sets?

 

Come on I know someone can help me out here?
