I've used the BFG MT on 3 trucks now and have really liked them for the Northwest. I think they handle fine in the Rain. If you get in snow very often, have them siped. I especially like them in the mud. (which we have in abundance) I got stock sizes, 35x12.5x17 to keep my horsepower from going to the rubber instead of the trailer. The 35's went everywhere the rigs with 37's did in Moab, but you did Potato Salad, with stock AT's. (You were The Man on that one.
) I disagree with Drty; I have had great luck with these wearing evenly and they stay balanced. I think he should rotate his tires once in a while if they wear unevenly.
I have a set of Cooper Discoverer AT on another rig, and they are crap. The tread is great, but they won't stay balanced.
Since I said all that, I'm thinking of changing wheels and tires again as well. I'm changing my rims for some with more bling, and I'm thinking of going with the Toyo Muds like Phil and so many others. I just need to find someone that's had them out in the NW muck to see if they work like I'd like them to.
Have you considered the GoodYear MTR? They only come in 18 inch wheel sizes and bigger.
Good Luck!
