My MB GL came with 20" run flats which I thought was fine. But when I replaced them with non run flats 3 years later, the car felt much, much more comfortable, less noise etc. The car felt completely difference in a good way.

I know most BMWs come standard with run flats but looks like I can order the X7 with non run flats with a spare. Also, snow/ice performance was terrible on the run flats compared to the non run flats.

Is there any reason to stay with run flats if I'm not concerned with the occasional flat tire change? I love the look of the 22" rims but not practical for snow driving for skiing.
