I know that our resident experts, Lonnie and Glenn usually can answer all of our questions, but I found this handy little conversion site to see just how tall/wide a different size tire would be on our Montanas and tow vehicles. A good bookmark maybe?
For instance - according to this calculator - a ST235/80R16 is 31.7 inches tall and a LT 265/75R16 is 31.6 inches tall. BUT... it is one full inch wider...
Glenn, I didn't check to see if this was on our Montana Owners web page?
