I installed these tires just over 5 years ago. The factory tires croaked at 38k! I anticipate having 80k on these tires when I replace them. I'll replace them before winter, otherwise I could squeeze a few more miles out of them. The tires performance is above average to excellent in all other respects, in my opinion. So the great mileage makes them a no brainer to me. I have carried heavy loads, gone off roading on rough 4x4 roads, pulled heavily loaded trailers into the local landfill (always in adverse conditions) and had NO issues.
