I just replaced my Michelins with another set of Michelins. The original Continentals went about 30,000 before they were worn in front due to bad alignment from Airstream. I also had an inner dual fail that overloaded outer tire. I replaced all six tires with Michelin LTX MS/2 in 2014 in preparation for trip to Alaska. They went 90,000 mile over five years and started to show small sidewall cracks and fronts had some uneven wear. The new tires are Michelin Agilis Cross Climate. The ride is great and I imagine they will wear like most other Michelin light truck tires.
