The old Take-off tires used to come with a temperature chart which directly related compounds to weather, ie: temperature.
That is track temperature!
But one thing to remember also aswell as rubber compound being suitable for the temp of the track is that you can run your car on a grade of tire meant for a hotter track but run them with a harder insert to generate the temperature needed. (Avoiding the "Cold scrub wear you mentioned!)
You need to open the breether hole too when doing this and its also very easy to overheat your tires when you run with very hard inserts. But if you get the combination right and your able to run with very hard inserts without overheating your chosen compound of tire you will have imence grip, low wear and no overheating of tires!
