We use our XUV for everything - highway, around town, and even for plowing with a Western plow. The Firestone Dest A/T's are just the perfect tire. Even with 30K miles on them they are quiet on the highway with nice, responsive (for an SUV) handling, they get great traction in mud and snow - even when pushing a plow and snow uphill.
They have also worn very evenly. With infrequent rotation and a set of bad shocks for a whole summer (thanks to the plow), and even under-inflation for a couple months, the wear patterns are very even across all 4 tires, with no trailing ridges or other unevenness. Great tires, and we'll be replacing this set with another when the time comes.
