when I want to put 18inch rims on my 04 9-3.

Meaning what are the numbers I should be looking for? tire size, off set. etc...really could use your help..

I am really wanting to spend the money the government is giving us on my car..woohoo/...

 

Look for 5x110 bolt pattern. Tire profile will be about 40-45.
