It's been mentioned on the old forum and it's still happening in the challenge at LRP so I think it should be brought to your attention:
I just bought the BMW M1 Pro Car and think there is a problem with the tire modeling on this car. The tire temps do not behave correctly as they should. Even though the CG weight distribution being more in the rear, the rear tires often exhibit excessive tire temps compared to fronts. When the car oversteers a couple of times the tire temps seem to get out of whack and it hard to get them to start behaving without restarting. I've seen sometimes the right front tire will show no change or very little in temps after spinning the car a couple of times. I think the massive oversteer problem on this car is related to the tire model and tire temps not behaving correctly. With the rear tire temps so high at times it's no wonder it's always oversteering. Also one thing that I hate when you have an all white car is that you can not see the rear brake temps. Maybe SRW can change the text color for white cars.
Yes the rear tyre temps are a bit strange, I had a relatively slow speed spin at Silverstone and gave it a bit of throttle to spin the car around, the rear tyre temps climbed very high and the back end then slid around very easy, so I looked out side and both rear tyres were flat!
