How much would a good set of 17's cost without the rubber? How about a set of 18's? And how much for the 18 rubber?

if you are in canada, try these two emails:

Juan@lightspeedinnovations.com
Sales@bigwheelz.com

tell them Alex from Vancouver sent ya. You'll get a great deal for whatever rim&tire combo. The first email above u will probably get a better price. The second email is a guy who specializes in wheels. So better try both. Good luck.

 

If you go with forged aluminum 18" rims, you'll probably spend at least US$450 per rim. Cast aluminum rims will usually be cheaper, depending on the quality, but they'll usually either be heavier or weaker than their forged counterparts. On tires, I'd say you'll spend at least US$150 each, usually more if you go with wider tires. With my tire sizes, I'm looking at at least $180 per tire for the fronts, and over $200 per tire for the rears.
