Do the Rocky Mountain ATS have the snowflake symbol on them?
BFG AT does, Toyo and Nitto's don't, but Toyo is still decent.
By the way, Duratrac's = Nitto's with chains (based on where 4wd was needed on final approach to the cabin).
Funny comment from my 80yo aunt as I was driving her and my parents up to the cabin Friday night. I had mentioned that these tires (Duratrac's) were great in the snow but would be reserved for winter use only since they wear out fast. She said something along the lines of, "well that's what we used to do in the old days before all this new technology came along." What's old is new again. (Oh, and she drives a '94 cruiser with all the lockers and stuff.)
