This is the first time I have gotten more than 40,000 miles on a set of tires. I'm not sure if it's the tires or the car, the BMW X 3 almost wants to be driven hard . The faster you go the smoother the ride .I live in St. Louis , Mo. We get all kinds of whether ,110 and dry last summer, 05 and 6 to 7 inches last winter, not one problem even on unplowed city streets. Good tires, looking for SECOUND set. 04/12. Al. N.
