I have been storing mine since I got it in 2007. Slightly over inflate tires (3# is enough), fuel stabilizer and top off, then you can use a TENDER, not a trickle charger, if you want. I did not the first 2 years and my car was fine after a few months, but the last few I have cause I do not want to kill my battery for a mere $20 savings.
My garage is not heated but is insulated. I have not put anything under the tires and it has been just fine each winter. My bike does get stands because those tires warp a lot easier and get brittle. The car HP tires do not in my experience.
