I like the idea of wider wheels. I came from a X5 with the Msport wheels, so nice WIDE rears. Anyway, with your set up, you actually reduced the diameter of the overall wheel (

I have the stock 21's. For the fronts, I probably wouldn't change from the 245/40/R21 to avoid any rubbing (I hear some rubbing at max wheel lock turning left, but that's another story), but I could increase my rears to 315 series. That would rock.
