A friend of mine has the PSS ZP tires and they've cracked just moving it 8 feet in -15 weather in the garage. All 4 tires were cracked and replaced in spring. I wrote a letter to Michelin asking about cold restrictions for these tires. At +4 deg. you have little traction. At -7 deg. celsius tires can crack. It can be parked in low temperatures but not moved until tire is above -7deg.
I park my car in my non heated garage. Temperature has reached -20 inside at times. Come spring tires look great. I store my car on top of rubber pads( 3' x 3' ) i purchased at Home Depot for about $25, cut into 1/4 sections. then place a piece of carpet between pad and tires. Seems to work well.
