traydenbellean - I don't think they are. Run flats have a near solid side wall and these have none.
Please see attached a pic of one of my runflats - believe it or not when I rang BMW assist they insisted that I was safe to continue my journey
Even when I told them that I could fit my fist in the hole the operator still urged me to try some tyre weld
No - I didn't drive it and they eventually picked me up.
Still impressed though as I was doing 80 with 5 on board and only suffered heavy vibration at the rear. No damage to wheel and the side wall was still supporting the car (that explains the hard ride). Mind you, I'm still cross that I hadn't noticed the uneven wear on the inside edge - guess what I do very frequently now.
