There's a solution to mounting those cold tires.
Make half a cardboard box - big enough and deep enough to fit the tire. Put the tire on a couple three little 2x4 blocks and turn the box over on top. Slide a shop light (with an incandescent bulb) underneath, and then put a couple of blankets on top. A meat thermometer is a plus. Bake at 110 for at least an hour.
No matter where you go - there you are.
