I Don't know if it's really a bug.
Maybe it's a known "old" problem which was already posted. I just drove some laps on BW in the TV view (Z6). Well i can't describe it that good. Looks like the racing line texture isn't exactly on the ground. Therefore it appears on the tires. Watch the screenshots. On the second picture only the reartire is on the racingline (green line).

Okay thx for the info!

Ehm...question...How do i get the red stripe at the middle of the top ?? Hope You know what I mean
I have a white one but would prefer the red shown on your preview pic.

Very nice but another version with seatbelts would be great
