I ran the OEM Michelin LT265/70-17 E LTX AS on my '03 2500 Dodge/ Cummins for 113k miles before they finally wore down close to the wear bars. The tire had hard rubber with very poor traction on any wet/frozen surface.
The same OEM Michelins in a 16" LT E on a new '01 2500 Dodge/Cummins lasted 84k miles close to the wear bars.
Went with a Bridgestone Revo at that time. Huge gain in traction. Ran them for 68k miles till they made too much noise for my use.
I'm rural out here with lots of highway miles with very little city miles. I'm a conservative driver and don't square my corner turns like I see many LDTs/cars/suv drivers do.
I've always got over 60k mile out of light truck tires on 3/4 and one ton LDTs even the ones I had in service (hiway).
I still use Bridgestone or Cooper AT type tires on my LDTs.
