I put a bunch of LX6s, FZ5s, and RACs on fern bay club. What I noticed is that the AI kept locking up their brakes, and then eventually from all the flatspots, the right front on the FZ5s would pop. The AI would go to the pit to replace the tire, but they don't know to adjust for the flat tire, so they skid past the pit box, and then are unable to pit, so they just drive off with the flat tire. Maybe I just have to clear the old AI training from the previous patch, I don't know.
