Last year I phoned Pirelli and confirmed that they don't recommend the Corsa's be exposed to temps below 50F/10C. Not to drive, and not even to move or roll the car on. The person I spoke to said that he had personally seen Corsa's that had survived as low as about 40F/5C. Some may think that is nonsense, but that's what is recommended, and he says they sell a lot of them as replacements for ones cracked in low temps. Porsche ships cars with this tire in heated trailers in cool temps to prevent cracking these tires.

Vipers like the TA2.0 with these tires that have left the factory in cold temps recently should have their tires inspected carefully for damage as a precaution, even if it was ultimately delivered to a warmer part of the country. It was 32F/0C at the factory this morning. I received a new set from Atlanta yesterday, put them indoors immediately right off the truck, and it snowed here this morning! If you're waiting for your new TA to ship that may not be such a bad thing.

I had to store mine mid-October to pull the wheels off and store inside last year and won't see suitable overnight temps over even the next two weeks according to the 14 day forecast. Hopefully they will be wrong as my first track day is May 6th. Daytime high looks good though so I may put the wheels on the night before and put a bit of heat in the garage.
