Yes, simply sell the wheels. I'm sure you can come close to getting your original investment. You can look at this way, you didn't pay to have tires mounted and balanced and sales tax, if they were used (apparently). That money is always lost, so even if you take a small loss, you will come out.
Give them to hbrand to sell on Ebay. He'll get $10,000 for them and you could settle for half.
