These are some Michelin PSC2Rs on a new C8 in a dealership lot I've been doing E36 M3ty underpaid gig work at recently. A couple days ago it was -8C in the daytime and it's been around -15C here the last few nights. There are probably a dozen more C8s just like this there. They drive them from trucks to the lot at these temperatures too - I saw that last time I was there and it was around -8C, and today at around 0C.
Now one Michelin tech bulletin doesn't say that the tires can't be stored in these temperatures, but basically says that they shouldn't be touched at -10C or less and should be warmed up to 5C if they have (reached -10C):

But info from another region has the more familiar advice of not even storing them at -10C or less:

Should the dealership be letting this happen? Is some New Balance-wearing old dude in jorts gonna blow up his tires approaching Moss Corner because of this?

IIRC, Chevy ended up replacing a bunch of 'Vette and ZL1 Camaro tires 5-6 years ago for similar negligence...
Depends on if you want to get involved. Depends if you like your job.
The five or six year ago situation apparently had the tread faces breaking, like huge cracks. The trouble was very obvious, apparently.
My question then, and now, is " How stupid do you need to be to sell a car into Canada on tires that can't go outside for 5 or 6 months of the year?"
Reading this, my thought is that replacing all of the tires would be far cheaper than explaining to your lawyer, and then a judge, why you didn't. And possibly even with a grieving spouse involved.
Unfortunately, people don't typically think that way.

"Hey boss, I remember reading about an issue 5-6 years ago that had this happen. Should someone be looking into that?" And then never mention it again

He answered that in the first sentence.
I'm not employed directly by anyone at the dealership so I don't have much to fear from getting involved. I'll mention it to them next time I'm there.
Funny enough the most gig-imperiling thing that happened while doing this kind of work was caused by me just being in the wrong place at the wrong time and getting blamed for some unknown dealership worker's screwup that I had nothing to do with. I haven't got any work from that dealership since...
From in inquiry I made to Continental they said to not allow my ECS tires to hold load below freezing. Also they recommend not driving on them below 40F. ECF's must be the same.
We don't get freezes much where I live but when I know its coming I take off my tires and stack them in my living room. (No female in the house so I can put whatever I want in my mancave home.)

I didn't have a choice when I picked up the BRZ back in December of '22 having a bunch of work done. When I drove it home it was -13 F outside with a wind chill of -22 F. The lack of grip from 245/35/18 ECS was hilarious.
It was so cold, I could hear and feel the fluid in the Torsen diff was partially congealed.
