I have run flat tires on my BMW which I've had for about 1 year and 5 months now and I get a flat tire about every three months (I got my SIXTH flat today!)and I hardly Drive the thing!! I use it as a second car. These tires cannot be repaired and can range from $380-$480. So every time you get a nail you HAVE to get a new tire. This is soooo not worth the convinience of having run flat tires. If you do decide to get these tires for your car I HIGHLY sugest you purchase tire insurance if your dealership offers it. Unfortunately no one offered me this until after my third flat and no one warned me that these tire were this terrible. I hope this will help somebody out there so they won't suffer the way I did.
