                Plywood under tires of a stored vehicle is an insulator against acids in aggregates that can weaken tires.

Plywood under tires of a stored vehicle is an insulator against acids in aggregates that can weaken tires. 
Moisture migration from concrete will also rust the underside of the frame.  I put used carpet strips on the floor of my garage and always park my bikes on the strips.

                For the 2.5 to 3.5 months it is to cold to ride I crank the bike up 2 to 3 times a week.  Let it warm up, it sits in the garage, and after it hits over 150*F then just ride it out onto the driveway and then move it back inside.  Once it is warm, I rev it a little, low rpm rev, and after about 30 mins of run time I turn it off.  Worked well last winter, no need for a tender, and it gets fresh gas at least once a month.  Plus I add fuel additives Octane boost and stabilizer.
