Tire warranty is voided if driven in temps of 20 F or lower.
They are "summer performance" tires.
What warranty?
There is no warranty on tires!
And yes, they are "max performance summer" category, for sure, which was one of the value for me in the Performance upgrade on P3D+:

OP has traveled as far as Wyoming in his P85D and experienced -24ºC (-11ºF), so he needs at least all-season tires, if not proper winter tires
If OP drives to Wyoming in the winter, all-seasons will be worthless.
He needs proper snow tires!
Michelin PS4S also suck in snow btw, not that anyone is/should be surprised and driving in snow will void the warranty and potentially damage the rubber compound.
PS4's don't exactly suck in the snow, they just spin harmlessly, and keep the car safely in place!
You absolutely can NOT (and should not) drive over snow/ice on summer/performance tires. At least not past the nearest ditch.
