Life is good, last Sat. I took the X to the local Ford dealer and they installed a set (5) of new tires on recall.
Not bad as the original set had 66,184 miles, I hope I get another 66K out of this set.
This X is used to tow an enclosed car trailer with a total weight of at least 8500 pounds, the tires were rotated every 5K and presswure were always 55psi.
