Thomas, I put Continental DWS06 all seasons on my second set of rims. They are not run flats, but are a perfomance tire, which are good if you end up encountering mild snow or ice also. I wanted a tire that I could feel confident driving in the mountains in spring and fall. I can confirm they have a nice ride and are much quieter than runflats. After 20000 km on these, they are wearing very slowly, ton's of meat left. I am prepared for minor flats with a jack, wheel wrench, plug kit and compressor. Purchased thru Quatro tires down East, very reasonably priced. Read the reviews, higly recommended.
