Race Engineering: How tyre temperature affects grip

How tyre temperature affects grip in a racing car is a non-linear problem (see chart.)

A tyre will have “no grip” if it is either:

  • too cold –> think rock solid. Rubber not able to “bite” into track surface.
  • too hot –> think chewing gum. Rubber so soft it can’t transmit forces.

In testing, find the optimum tyre temperature for your tyre on your specific track.
