Thought I'd add my HOW-TO here as well instead of starting a new thread. These are GTR rims with tires (no lip) shipped from Seattle,WA to Boston, MA (yup, across the whole US)
First I cut out 8 circles from 1/4" MDF board (hard, smooth press board). Radius of about 1" overlapping all the way around the rim.
Went to walmart and got some cotton fabric (don't mind the bunnies, couldn't pass up a killer deal on some post Easter print). Clean the face of the wheels so nothing gets caught between the fabric and finish. Cover the face of the wheel with fabric overlapping onto the tire.
Put the round 1/4" MDF piece on the fabric.
Tape it down in a star pattern (don't worry about taping it to bare tire, the tape will come off.)
Cover the back side of the wheel with MDF as well (no need for bunny fabric here as the MDF sits on the tire and no protection from scratches is needed.
Shrink wrap that sucker. Then tape in a star pattern again as well as along the thread of the tire
More shrink wrap and some stronger duct tape.
Done!
According to deeto (buyer) these came to him in great condition. It took me about 2 hrs to pack all four by myself. Well worth it though rather then dealing with shipping damage. This is a pretty solid shipping method but I'd recommend shipping insurance anyway.
Deeto should be adding some unpacking pics later on
