Down to what temp have you safely used the OEM ITS tires?

I mean for semi-normal driving, not racing and dry roads.

Most resources out there say 40* F. We're having a brief cold spell, and I have not yet put the winter tires on.

TIA

I've driven the precusor to the factory tires (PSS) down to 44 degrees once because I had to move the car to another city. My biggest concern was less about grip and performance (though there was certainly lack of it) but more sidewall cracking.

I drove gently and had no issues because I was able to keep the tires mostly warm at about 50 degrees (my previous car had tire temp sensors) but I probably wouldn't drive them in sustained cold temps REPEATEDLY (key word) for too long. If you're just waiting on tires to be delivered or something then I think you'll be fine if you don't have to move the car on those colder days. A couple of times just to get to the shop would probably be fine.

Yes keep it above freezing in terms of storing however many of the cars were delivered in winter in the norther part of the company. Driving (gently) at 35d as needed if you garage the car is not too bad in that the tires have some heat in them. None of those cars exploded (mine included: took delivery during a warm spell in Feb but still was not over 45d f

The biggest issue I have seen with summer compounds isn't just temp, but wet performance coupled with sub 50d temps show them getting far more squirrely.

If storing outside with repeated overnight temps at 40 or below, get A/S compounds or winter compounds.

Yesterday morning was 36F when I left for work and I noticed no adverse effects. My commute is ~10 minutes of backroads, followed by 10 minutes of highway. The car is garage-kept overnight.

My new wheels and A/S tires are due the first week of November.
