I have the 275/50/17 m and h. I've run the 3 seasons running at least twice a month 3-4 runs a night. They still hooked good. I drove the car 100 miles round trip in the mountains no problems. I even got caught in a huge rain storm on the way home from work with no problems. The m and h drag radials were money well spent. I think I have close to 4000 miles on them now.
