Perhaps forcing the AI to pit when a tire's pressure reaches a critical level would help reduce these punctures.
Also I noticed that some of those punctures are caused by the aggressive braking technique they use. Comparing with my driving, I find that they heat up the outside tire alot less than me, however, because of the braking, they lock up the inside causing it to heat more than when I'm driving.
The AI is particularly fast in South City Chicane with the FBM, I did a race with them and just couldn't keep up, it got worse in the final laps when my left front was hot and theirs was just fine.
