If you look at every tire on a modern GT500, ZL-1 Camaro, Corvette, FGT Ferrari etc. They will have a disclaimer that the tires are not to be considered safe under 45 degrees.
It's the price of having the high performance adhesion.
You need an all-season radial to do what you ask. BFG might be the best, or only choice.
But those aren't track tires.
My reality is that it's very unlikely I would be interested in driving the car in the cold anyway. I'm just looking to get as much feedback as I can.
I already know about the adhesion issue with low temps from my Pirelli P7's. They turn into the proverbial "banana skins", interestingly enough right in that 35-45 degree area. The tire rides very hard at those temps too. Like it is concrete. A lot like the old Polyglass tires did?
BFG's are what is on the car now and they are a compromise tire BUT very predictable. Incidentally, they don't like any kind of water either.
The question here, now, is where I want to compromise? I have to go back and read my own criticisms.
I was looking for the Avons at the last SAAC convention and didn't have much chance to investigate them in person.
I want to see where everyone is located with these things too. The Avons sound like a perfect LA tire to me? I wonder if they love 'em in Green Bay? Hey Jim?
