Hi, I have a couple of questions.
1) what is the difference between tire temperatures displayed under F9 menu normally and when pressing SHIFT+CTRL?
2) how are the average temperatures calculated in the single player output data? They seem to be much lower than the temperatures I am having at the moment.

However, these numbers only represent the average temperature of the whole contact patch (from the inside up to the surface) - if you press and hold Ctrl+Shift, you can see the the actual surface temperature, which rises and falls much more quickly during a race.

Thanks, any ideas about the second part of the question?

Maybe temperature inside the tire (air)? Would make sense if that is usually lower.
