Jared, Dan has a good idea except, Iwould first send copys of the documents ,then if they make an effort to return your money send the tires. You don't want to end up without the money and tires. I would also make sure all corespondance has proof of delivery .
When you file with the internet fraud task force you will recieve an id #so you can update your report later. Hopefully to report a positive resolution . Later ,Tom
