As you can see from the graph, tyre pressure on front tyres just explodes without any reason. This was recorded with default setup, standard conditions, le mans track, le mans aero package. No wheel lock at all, it was in my first ever lap of session. The bug seems to happen at high speed when reaching 310kph or above. Another small bug is present when braking from steady state: when you exit the pit, upshift to 1st gear, then try to push brake pedal when you are still stationary. You can see the rear of the car lowering a bit. This was a common bug that i experienced also when building my own mods. I always solved it by moving rear pushord pickup points. EDIT: Something similar happened to me 1 year ago while I was building a custom tyre model. I solved the "exploding" problem by lowering the ring stiff multiplier to get lower frequencies. So it seems to be a solution stability problem.
