Maybe i am wrong, but should'nt the front tires on the Beemer reach normal temperatures during racing? Just get them between 55 and 60°, rear tires easy up to 85°. I know the FF cars have very low rear tire temps, but the Beemer is a rear driven front engine car. So it has much more weight on the front axle, compared to the rear axle of the FF cars. But the front tires stay cold, and you have no chance to get them in a working temperature window. Thanks for looking.
