Default The importance of track temperature.

The concrete track I run at has a temperature of about 90°f at the open of practice, and a temperature of 120°f at the start of the mains. My experience of last summer on an asphalt track says, on an equivalent day the temperautre would reach 140°f. I don't really understand this, but this is what I have observed.

Take Off tires are very popular in the US. This is noted by the various tire threads on this board. The application of Take Off tires seems to be at below 120°f the CS27 is used and above that the CS32 is used. The Sorex 36r tire is just comming into its range at 90°f. At 120°f I believe it is in the middle of its range, with 150°f being the top of its range.

I can understand the confusion with these tire numbers. The 27, 32, and 36 numbers are suppose to be Centigrade temperatures. The temperatures that these compounds operate best at don't seem to be well related to the temperature numbers of the tires.
