Sure, roll them in the house...just make sure you park them on the dining room wood floor!!!!! Then you will want to break out the old shovel to move the snow as you will have to keep warm somehow after being thrown out!!!!
I had mentioned tarping like making a tent. Keep the flames and torpedo intake away from the tarps, though. We have unthawed truck blocks, frozen brakes, artisian wells (blow the heat down the well shaft to thaw pipes, etc)
BP Flick is right that a nice temp over freezing will do well for you. It is not exciting to watch, but it will work. Some ice flopping around wont hurt the tires. Put the valve on the up side, dump RV antifreeze down the stem with the valve out, and you will be golden. Don't use radiator antifreeze as it is toxic and will go all over should you blow a tire or re-break the bead, causing danger to your animals and envirnomentalists won't be thrilled, either.
Grab a cold one, put your feet up infront of the fire and watch it snow....the tires will be cooked soon enough! Good luck!
