Dunlop run flats

Dan, I think there is a problem. As far as I can tell, the inner tube for a runflat tyre is much smaller in diameter since the side walls are so much thicker (4"). So using the same inner tube in a normal tyre like the Michelin, means you will have to overinflate it to fit inside the tyre properly. Not the way to go, I think.

My €0,02 worth.
