Question on 19" - XBimmers

danx3 · 05-11-2011, 08:11 AM

I am planning to have a set of aftermarket 19" wheel, can anyone tell me what is the difference between front 8.5J x 19 245/45 & real 9.5J x 19 275/40, compare with front & real 8.5J x 19 245/45?

Since it is a X drive vehicle, shouldn't it be the same at front & rear?

The diameters of the 245/45/19 and 275/40/19 tires are pretty much the same and won't affect the xdrive. I would think that wider wheels and tires in the rear would produce a bit more understeer than a square set up of all 245/45/19 tires on the wheels.
