Folks, I am about to go the non run flat route as well, 2nd flat in 1 year and rear 19" to boot on my 335i. BMW dealer in Canada is asking for $850 per tire!!! also have been told I need to sign a waiver and my Roadside assistance is void if I get a flat on non RFT. Havn't made a decision on wich tires I should go. Not so concerned about flats as much as a tire with a strong sidewall in the event I hit a pothole at highway speeds. Any feedback on Kuhmo tires?
