When i had the RR, i had changed out the stock 20's to 22's HRE forged wheels... my experience then was the 22's didn't ride anyworse, just noisier (wider tires) and worst gas mileage.

the x5 already rides what i call a little "harsh" and i don't expect it to get better with 22's. But hoping others out there maybe has experience doing other mods that could make it a little "better"..

did you get the sports package? does the edc make the ride smoother? or is it the same ride quality? just more performance oriented.
