Racing cars sometimes have to have their tyres pre-heated in specially-designed, electrically-heated covers.
Today’s invention augments that process by using the engine exhaust flow to help warm the rubber.
Each exhaust pipe would have a nozzle, directable by use of a small motor, which could be rotated towards or away from the surface of whichever of the rear tyres it was pointed at.
This system could make use of a small thermal camera to gauge the tyre exterior temperature and then help divert the exhaust flow after the heating had had its effect.
A more advanced version could also warm the front tyres.
