I got 70K on a work van driving on interstates and 2 lane state hwys mostly. Not much city type driving. did pretty good on dry, rain wetted roads. not great for snow, slush or wet dirt/mud type environments. Doubt the AT version is much better.
Don,
which Cooper did you have? I've had a number of the AT Coopers, no issues, a set of CTD's before they quit making that style. Not impressed with the 19.5" traction on my dumptruck a number of years back......otherwise, I am happy with that brand of tires. Had 40 on different trucks, trailers etc when I had a few more running down the road than I do now.
