The Continental Extreme Contact DWS is among the best available for winter traction, however it is not available in a run flat tire. If you have the 255/50R19 size, the best available run flat all season would be the Michelin Latitude Tour HP ZP.

My 2009 X5 will need new tires shortly (255/55R18RF). Trying to decide between the current tires (Bridgestone Dueler 400) or upgrade to the Michelin Tour HP ZP at +$100/tire or $400 for the set. I don't mind the extra cost (well maybe a little) but my primary usage is around town, occasional freeway and never track/mountain roads. So noise, handling, wear, in that order. Need to stay with RunFlats.

Suggestions?
