...one more thing. I wrote to Continental Tires to ask about winter storage tips for the run flat, all season tires that those of us in Northern climes tend to have. I know there is a blurb in the manual, but I would rather hear it from the tire maker. I also asked them for their position on nail/screw puncture repairs, since a recent autoweek(?) noted that of the companies making run flat tires, Continental was one of those that did not have an official position on patching. Not that I have a puncture, but lets face it - it's a common thing.
