Same on my Dually. Michelin Primacy XC’S. Fronts wore out at 35,000. Rears look damn good still though. Shop said I have so much weight in the utility bed it causes the fronts to wear? Who knows. Either way, bought a set for the front and figure they’ll last til the rears are worn and I’ll switch to Toyo’s?
More likely that heavy assed diesel in front.
