It would be cheaper to just send back the wheels probably.
But if it was me, I'd call up DTD and order an entirely new wheel/tire set and they'll ship to you already mounted and balanced and ready to go. Then return the tires and wheels you've got to where they go and be done with it. That's the nice thing about getting the wheels/tires as a set from DTD...you save all that cash and hassle because they show up at your house ready to bolt onto the Jeep.
