Got some new tires for the car, the fitment is perfect now in my opinion. Also running a 10mm spacer in the rear and 5mm up front.

Your vehicle has great stance!

Was curious to know any reason you'd increased the tire sizes using OEM wheels? Would this impact the xDrive system since the overall diameters have now changed? I was informed in the past that these tire sizes were ideal for wheel sizes (front) 20x9 and the (rear) 20x10 in order to keep the overall diameters highly similar to factory setup. I think the OEM wheels sizes are 20x8 (front), and 20x9 (rear). Thx.

DWS? Thinking of doing something similar...

I went with a bigger size because I was tired of running run flats, due to the harsh ride. And thought to just increase the tire size by 10 all around. There hasn't been any issues that I can speak on, the car still drives normal, better than before actually. The only issue is the tire pressure monitoring system, it doesn't have a setting for my specific tire sizes, and the other tire option isn't working so I'll have to get that sorted out.

Is this xDrive? Are you still running this setup? Any issues with xDrive system or transmission/center diff?

Your stance looks great! I have alpine white with same rims and wanted to go a tad wider on the tires. New rims would be cool but I don’t mind the stock rims.

Is the TPMS still working with the new wider tires or is it throwing codes? This is great information for me to know.
