Look at Nitto Exo Grappler. For some reason their not popular however im very happy with mine. I was looking for an all around good snow long last tire. A couple people have them on the cummins forum and theyve lasted around 40k miles.
They have the snowflake for severe snow rating. They have large deep lugs and work great towing with minimal noise. My 5er 14.4k lbs and im 23.7k combined. The noise stays nice below 70. When getting above that they do get louder. My wife didnt notice a differece from the stock firestone AT
