I have had the HT3's on since July of 2015. I have put about 10,000 miles on them. They are a good tire so far. I have a 2003 Winnebago Minnie 29B, I am told this is a heavy unit. I have never weighed it. We travel with a family of 5 (2 adult and 3 kids) and a dog. All the stuff that goes with us as well. I also travel with a full tank of fresh water. I have not had a problem yet. I do not rotate the back tires, and only cross the fronts left to right. I do not see a problem getting 10 years out of these tires (I park the unit inside when not in use, so no UV damage). The tires are wearing very well and look almost new still. Other than the typical Ford TTB tire chop on the front, which a Ford will do to any tire, hence crossings fronts, these have been great tires.
