Re: creepy tires:
Try not inflating to full pressure until the glue is set. I inflate enough to make the tire firm and stable enough to get a good purchase on the rim. If you inflate to full pressure before the glue is set, you run the risk of forcing the cement out from under the tire where it belongs, to the edge of the rim.
I usually partially inflate, let things sit at least overnight, inflate to full pressure, and let it sit again for a period of time, even overnight again.
