New to the Galant World

Hey guys, my name is Jean and I recently purchased a 2007 Galant. I came upon this website due to trying to find the cheapest price for a radio bezel. Since last night, I've read countless threads about what everyone has done to their Galant and it made me feel proud to own such a car. Right now I really want to change the tires, but which ones to get or what size. I'm leaning towards 18'' atm. I don't want to break the bank with the purchase, but at least I want decent one. Does any one have suggestions? Thanks.

Right now for some reason it will not let me post pics. If you want to see pics just let me know and I will send a email.
