Very long life, but traction is not great.
I tow my race car with the truck, probably 90% of my driving on these tires is highway cruising. The tires were on the truck when I bought it 5 years and 80,000 miles ago, and still have tread left. They just don't wear out.
The downside to these tires is they don't grip the road very well. It is easy to lock up the tires under moderately hard braking in wet. They are not amazing in snow either. I ordered a pair of Blizzak DM-Z3 tires for the drive wheels after getting stuck trying to pull the trailer out of its parking spot one day. I had an opportunity to drive on all 4 of these tires in a snow storm last year and the truck felt squiggly. That said, I run the front pair of these tires on my truck year round and they work acceptably well as long as they are not asked to do too much.
I swap out the rear tires for Blizzaks in winter and even so the rears are wearing out somewhat faster than the fronts. This is probably due to the front axle carrying 2,000 lbs and rear axle carrying 4,000 lbs of weight.
I'm looking at picking up a pair of Load Range E tires for the rear axle as I'm too close to the load limit for comfort. But if it wasn't for that I would get Destination A/T again in 1-2 years when mine finally wear out.
