Best way to ship OEM wheels/Tires?

[SoonerBoarder]

Get some cardboard and a roll of shrink wrap. tape the cardboard over the face of the wheel then wrap the shrink wrap around the whole tire. Keep going until it's covered, then tape the ends. It will look like a giant plastic hocky puck.

They will probably be too big to ship USPS. UPS will do it, though. Either go to a UPS store or find a buddy with a UPS account.
