This very topic has caused extensive debate on the Sportage and Sorento forums.
The concerns are that due to the 4X4 transmission being part time then a big disparity in the tyre circumference will be confusing the sensors and trying to activate the 4WD
Rotation of tyres and keeping the disparity within 2mm seemed to be the guidance.
Then recommendations to put new tyres on the front which is against the industry recommendation to put fresh rubber on the rear on any vehicle.
Certainly concerns were voiced regarding transmission warranty claims, in that the first thing they would check is that the tyres all had similar circumferences.
The jury is still out :/ with continuing difference in opinion. So it may be worth trawling the BMW forums or a good read of the handbook to see that you are not leaving yourself exposed regarding a warranty claim, if infact that is the case.
