I also own a BMW 650 which does not have a spare tire and therefore originally came with Bridgestone Potenza run flat tires. I need to purchase new summer tires (19") and, in a perfect world, would love to break away from the run flats and go to a better tire like the Pilot Sport PS2. However, I am concerned that because I don't have a spare I will be asking for trouble in the event I do get a flat. I was hoping other SC owners would be able to share their insight with me on this issue. Any thoughts? Thanks in advance.
