Paypal has a feature where you can do a charge back if your purchase was "not as described". Its easy to do, just file a complaint with paypal, there is a drop down menu for why, select not as described, they send you your money back, and you send the wheels back to him at his cost. easy as that, ive done 2 of those in the past 3 years ive had paypal.
