I have regular P Zeros on my car (400bhp+ RWD) and they were atorcious this morning, temp was 3 degrees but road bone dry. Moderately accelerating in third up a hill the back end was squirming around all over the place. Going to replace them with Michelin Pilot Sports once they are down to 3mm.
Us Mustang drivers know how atrocious the OEM fit P Zeros are in cold conditions. When the tyres warm up they're ok but the first few miles are hilarious. I changed mine to MPSS and it's like a different car. Seems to be widely believed that the P Zeros fitted to Mustangs are a US compound, and less suitable for cold weather than P Zeros sold here.
If tyre manufactures generally sell different compound tyres under the same name in different markets, perhaps that accounts for some of the disagreement in this thread.

This is absolutely true, and the difference since the weather got colder is very noticeable, although, like others have said, OK if you treat the go pedal with respect.

Yeah I heard that too about them being a unique US spec. Not sure how true that is but they were very bad in cold temps. It didn't take long to get rid of them though Seems to be widely believed that the P Zeros fitted to Mustangs are a US compound, and less suitable for cold weather than P Zeros sold here.

I had 595RSR's on them before, and I could find the limit of them much, much quicker than the AD08R's. Wet grip especially is massively improved on the Yoko's
I also have AD08R - 245 - 40 - 18I had 595RSR's on them before, and I could find the limit of them much, much quicker than the AD08R's. Wet grip especially is massively improved on the Yoko's
Once warm they are fine . You have to be driving well outside the "safe" limits to find their limits on a damp and greasy day.

PZC are OEM on my Exige S - I've stuck with them since getting the car in 2013 - Can be a bit twitchy when cold, but easy to warm up at completely legal speeds.
Living in Glasgow, we've had a fair number of sub zero mornings recently - Drive to the conditions and warm them up, and they are fine.

Still intrigued by the Corsas in cold weather.
-2 this morning, and didn't increase over 10 miles/15 minutes. Icy roads where left untreated, but other wise dry.
Tyres felt hard for first few miles, as suggested before, as if they were made from concrete, and grip not as good. But soon warmed up.
Pressures increased 0.3bar over 10mins as they got warmer and performance seemed pretty much normal then.
You're being too obsessed by the pressures. The pressure isn't the main variable here - it is the rubber compound. When they get cold, the rubber will get much harder and just not grip as well. The Michelin Pilot Super Sports on my M3 don't like the cold either. They probably take 25% away from my total available grip. -2 this morning, and didn't increase over 10 miles/15 minutes.

Of course the answer may be that in those cold winter parts of the US everyone has winter and summer sets of tyres, or just that they expect wheelspin in at least 2 gears!

Having tried them on several cold days, the lack of grip is no where near as much at 25% on the Corsas, ceteris paribus.
