I know that in general for GT3 cars, you want the tire pressure when racing to be around 1.80 bar or 26 psi. The default setup, at least for the GT3 AMG, is 1.50 bar, which usually results in a running pressure of around 1.60 bar. I know this is dependent on the ambient temps, but my tire pressures always end up around 1.60 bar. Just wondering why the default setup pressures are set this low? Is it that the setup pressures need to be raised, or is the tire model incorrect for how much the pressure increases from cold to hot? Like I said, the setup pressure is 1.50 bar and during a race will only go up to 1.60 bar.
