Was wondering about your reply, thanks. My standard setup that has 225/50/17 tyres, when I try to put my hand between the wheel/tyre and shock there is not that much room, maybe 20mm max, I hav'nt measured. That's why I was interested in your 9" on the front c/w 245/40/19's. BMW say to me 8"max. on front. I believe your original setup 18x8 with the offset of 30, I rang BMW in Aust. and after hard time they gave me that 30 offset. Using the above figures your new wheel/tyre setup - front 2.86% and rear 2.33% is just within the recommended 3% diameter of original tyre. I realize you have sports suspension and then changed to KW v1 coilover springs, is that what they are? Am I right. I'm just an old guy not to mechanically minded looking to change my setups and make my X1 look good. Things cost 3 to 4 times more in Aust. and it's hard going to find info. Sorry for annoying you guys.
