hey everyone I'm Justin from Wisconsin. I've got an 06 Grand Prix with the mettalic bluish green paint job. The tires I have on now are 225/60/16 and I am looking to get some 20s but Im not sure what size. I'm debating on 225/35/20 or 235/35/20.. which ones would be most similar to size to the 16s I have? Or is there another size someone recommends? Thanks a lot!
