All three of our Montanas, 2001, 2003, 2007, came from the factory with ST tires. For awhile, somewhere between our 2003 and 2007, Montanas were delivered with LT tires from the factory. Further, our 2003 came with D load-rated tires rather than E. When I questioned this our dealer gave me a copy of the following letter. Note this letter is from 2002. Also note the discussion on LT vs. ST tires. I don't presume to say any of this is accurate but thought it might be interesting for some to see what Keystone had to say back in 2002. I had to reduce the size of this picture to conform with forum guidelines. If anyone has trouble reading it, you can email me (envelope icon above) and I'll send you a more readable copy. Our 2003 Montana had the tire size mentioned and we found it very difficult to find replacement tires in that size.
