These are the run flats, so the bead has to be trimmed a bit to fit the older Brit/Canadian rims. But they will look the part. Don't be put off by the photos showing cracks or gouges. Derk is an honest seller, and will show the worst thats on them. Overall they are nice tires, and with winter here he will be ready to deal in order to get them off the driveway. And with the thickness of the rubber on run flats, you will never puncture them in civilian use.
