You guys in California can't relate, but I want good grippy tires in Kansas for ice and snow. I'm willing to pass on run-flats to get them. Michelin Pilot HXMXM4 run flats didn't last (18,000!), and I'm thinking of trying Michelin Sport A/S. Not many choices in this size. I put Goodyear Trip Treds on my Lexus SC even though they were not exactly the spec size, and they were great but none are available now (strike).
