I have checked Michelin and Goodyear's web sites and neither make replacement tires in the LT265-70R17E OE size. What gives???
It came with Michelins, so they did make them.

 

Michelin does make the that size of tire in the LTX A/S, but not in the M/S. Cooper, Mastercraft, Toyo, BF Goodrich, and Pirelli also makes that size.

Just picked up a set of Pirellis from Tirerack.com at what I concidered a great price ($108. each) and really like them. They got good reports and reviews. My truck came with the Goodrich T.A.s, and after darn near losing the truck twice on my mountain driveway. I decided I needed to change something. These actually have more of a street pattern, but are rated much better all around. They have a 65K mile wear warranty and they are a bit taller, which seems to be something most of us are after.
