After spinning out and then leaving the car standing still, tyre pressure continues to rise as if the car was still sliding. Observed this driving the mclaren gt3.
The sliding heats up the rubber which heats up the air inside the tire which increases pressure. This will take a few seconds until equilibrium is reached. Unless it never stops, that's not a bug.
Also brake discs dissipate heat energy into the rims and tires when they're warmed up - it's one heat network of various components. (when the car is in movement, there is more cooling action due to airspeed for example) I saw some influencer talking about "simplyfied physics" in AMS2 the other day - i'm always a bit bemused when hearing that
