What wheels should I get to fit my tires?

Hi all,

I have a 2004 330i ZHP. Currently have the stock 135 wheels with 225/40 tires in the front and 255/35 in the back. I'm am going to buy new wheels, but keep my tires because they have less that 5k miles on them. So, taking into consideration what size tires I have to work with, what size wheel should I get? Should I do a 18x8.5 square setup? Or 18x8.5 in front and 18x9.5 in the back? Keep in mind I am on stock suspension (for now). Thanks guys! :thumbsup

It really depends on if you'd like to be able to rotate tires in the future. What's more important to you? Tread life, or performance?

Also, what is better for the ZHP out of these two options for the rear...18x9.5 ET33, or 18x9.5 ET45? Would wither have an issue with clearance?
