I just ran a couple of laps with AI turned on and the MoTeC log does not have tire temps. Took it out drving myself and tire temps showed up in the log. Went back to AI running my car and tire temps disappeared.
Its ok. This is because AI's tire physics is simplified. They do not have tire temps, brake temps and something more. Also their physics calculated twice rather than players: 50 times per second with player's 100 tps.
