Tire: SottoZero 3 - Winter Performance, H rated tire in 215/45/17

Call Pirelli USA: Operating temperature maximum is 45 degrees Fahrenheit

Talk to TireRack: Operating temperature maximum is 50 degrees Fahrenheit

Conclusion: Tirerack is wrong. Interpretation is "Just sell the damn thing" - TireRack

Not a big difference? Someone will always not care about details and comment this. However, that really is not true. It is a technical question, and asking "what does the manufacturer say about the max range?". Also, if it is 56 degrees maximum daily temperature for 3 weeks, I would not mind driving a $180x4 set of tires a little bit above temperature for a while. But, 11 degrees above temperature would make me hesitate. I do not live in the mountains, I live on an Island. It does not swing more than 10 degrees F from night to day normally, often less.

So, if you got nothing else, at least you know the operating temperature range of the tire. Tirerack said no minimum temperature range, unlimited. Pirelli did not want to comment on the low range of the tire. I asked two people at the company, no listed official numbers they have here for lowest range of cold temps it is good for.

this might be splitting hairs at 45-50 F, but it is a hard numbers question that was not answered with hard numbers that Pirelli can readily provide. I dislike that.
