In 57k miles with my E46 M3 on 19" PS2s, I've had three slow leak punctures, but no "flats" or blowouts. You can repair a normal tire, unlike runflats. That, together with the ride issue, makes me favor this direction. I carry a plug kit and you have a compressor with the MMobility kit. In addition, on trips, I take a space saver spare. I'm happy with this vs. runflats.
