If you have a few more bucks, then the Wheel Fit by Wheel Works is the way to go. It can simulate wheels from 14 to 20 inches in diameter and 6.5 to 16 inches in width. Since it’s made from metal, you can actually mount a tire to it and spin it around to check fitment. The tool runs about $320, so it’s not inexpensive, but you can rent it out to your buddies and get some of your cash back. Besides, it’s way less expensive than buying wheels twice.
