235/35-19 and 265/30-19 are close in size...within 0.7%. But your post that I replied to said "This may sound stupid, but can I run same profile tires on a staggered set up to eliminate the xDrive issues? Say 235/
35/19 front and 265/
35/19 rear?" Those diameters are more than 3% different.
Don't know if your car is lowered or you have plans to do that. But 235/35-19 is a half inch smaller in diameter than the OEM setup which will increase the already generous gap between your tire and fender. 245/35-19 is a tick smaller in diameter than the 225/40-19 stock tire and 235/40-19 is (obviously) a bit larger.
Check out the comparison between the 2nd and 3rd pic in this thread:
http://f30.bimmerpost.com/forums/sho....php?t=1031765 As the car was lowered in the 3rd shot, the xDrive with 235/35-19 fronts and 265/30-19 rears was transformed from a piece of agricultural equipment to a Tomahawk missile...OK, maybe the tire dressing helped a little bit.
Bottom line, I'd be reluctant to pick 25.5" tires for an xDrive unless I had plans to lower it. A half inch doesn't sound like much, but in the context of wheels and tires, it's a pretty big change to make inadvertently.
Whatever the case, if you are seeing your traction control light regularly, something needs to be sorted out. Let us know how things progress...
