I finally broke down and purchased a new set of these after the old pair hit 80,000 miles. They are not at the wear bar, but close. Hear we have a lot of rain, black ice, and occasional snow. But I drive allover including unimproved roads, off road, and highways. These tires rock! I have had excellent wear, excellent off and on road grip in sun, rain, snow, and Ice. The ride is not as quiet as the old continentals this car had, but otherwise much better. I would not advise these for fair weather asphalt city dwellers, they can stick with basic high mileage tires, but these do not harm gas mileage much at all.
Please note my other car is a sports car with high performance tires and rims, so this car is driven where that car cannot or will not be taken.
