Hi Fraser, I fitted 265/65/17 ATR's... remember we had this discussion before in the thread below ;-)http://www.xoutpost.com/bmw-sav-foru...cs-2.htmlStill very happy with the Scorpions, have done 15,000kms on them and they still look good. Haven't had to do much 4x4 stuff, but I have lauched the boat in mud a few times and they do seem to grip much better than the old Mitchelins...
