Cold tyres.
Warm tyres give more grip than cold tyres. However what opportunity is their to warm tyres on a Sprint or Hillclimb? Do sprinters chose tyres that work better cold or does everyone have tyre warmers(!). Or are there burn offs as in drag racing?
What is the form in Sprinting and Hill Climbing?
And then there is brake temperatures.
Is the cold tyre thing part of the fun?
