I have almost 37K on my 05 Dodge Dually and am going to need new tread soon.
What are my Mud Terrain options on the Dually.
Stock is 235/80/17
There are so many options in 16's but I need to know "what will work" on my 17's.
I know most tire stores won't install "non-stock" tire sizes on a dually but if the will "actually" work I will get it done somehow.

I would preferr BFG MT's or Big-O XT, Goodyear is an option but I hear the MT's don't wear good on heavy trucks where as the BFG MT's do.

I plan on going with the Firestone Destination M/T. I think it's a better tire than the BFG, and comes in better sizes for a Diesel SRW that needs a high weight rating.

They only offer one 17" size though, a 265/70/17. Don't know what to tell you on the duals.
