Kevin, was more thinking about temps. Does it hurt the tire to let it get super cold. I mean not below freezing as the garage is not headed however its isolated. However it gets negative 30 in Wisconsin. When people talk about heat cycles in the tires I was also thinking letting them get super cold does not help. Thoughts?I'm not technical enough to answer that one for ya'
From experience, I haven't seen a modern tire flat spot, though. I don't think you need to worry about that. But if you want to be extra careful, could also get something like these:

There's a resource available that's even better than this forum - call Michelin's 800 number and ask them. They can tell you whether the tires will be ok or not.
I was having the same concern. I call Michelin and if the tires get below 14 degrees F they are shot (throw away, do not use). I didn't want to deal with putting it on jack stand and storing the tires, so I swapped them for A/S3+. (OE Tires were 75% to 80% worn at 3k miles with no track days believe it or not). So far I haven't noticed any shortfalls from the A/S3+ for public road use (still don't hit the limits in the dry, WAY better traction in the cold and/or wet, and improved MPG!).
Last winter I used the low profile drive-onto flatstopper race ramps and the SC2's remained round as new - first test of spring after 4-5 months in storage they were absolutely perfect.....HOWEVER that was in a heated to nominally 50F garage....this year not as lucky , no room at the inn (friends vette collection grew) and my build of a new garage project totally #$&%ed by covid impact job furlough then loss....still trying to figure out what to do - storage anywhere nearby is so damned expensive @$400+/mo. Tires only have 900 miles on them and not thrilled at spending on A/S3+'s or 4's etc when feeling a bit beat up financially. Aftermarket car cover was great except for wind - acts like a vacuum pulling grit up even to coat to the painted black roof where it then gets slapped by the wind. Hating 2020....though today is sunny & warm....time for a spirited drive out to some remote dairy stand for a burger & ice cream - worry about the rest after new work for hire job start 11/2.I'm not technical enough to answer that one for ya'

That seems a bit extreme. Was this specifically for the Cup2s? Did they give a reason why this is the case?
It was for the Cup2s and it has to do with the compound. Different warning on their site for those so I asked the question. (and yes it applies to the ford specific version for the GT350 too). If you search around GM has a lot of issues with new corvettes on Cup2s that got cold in shipping and cracked before they even got to the dealers I had PSS and PS4S tires on my 2011 GT500 and stored it for the winter on those without any issues.
Pretty sure earlier he said its to remove & store the SC2 tires to climate controlled storage.
Brad...are those the 12”? How did you get those under the wheels?
I'm not tire engineer but I've hung out with some at Indy so here's a thought: Compounds outgas & weep - what could be a grace period could change over time as the compound ages unlike a fine wine it gets worse.
Its doesn't have to be either or does it? Spit-balling: With some added planing as you let down each side you could prop the suspension with lower set jack stands or use the lower ~4" blocks or wheel cradles like the "display & show" ones Raceramps.com or similar sells. If you did it with jack stands buy better ones than what you showed for carrying the full chassis weight (those you showed look cheap AF - I like 4 point gusseted aluminum heavy duty ones with cast rack posts - better yet with also those 3rd party wider no move bases to set them in) & use the ones you already bought to prop the suspension rather than letting gravity hang it to an extreme extension (sag). Put thick leather or similar between suspension stands, or buy the jack stand rubber contact caps, to not mar up anything not carrying the full load of the car.
