What part of the country? Sounds silly but not all mud is the same. Down here in the Southeast it’s stupid slick clay based mud. Also what kind of use will the truck see? Occasional muddy field? Mud bogs? Muddy trails?
I’m running the Maxxis Razr M/T’s in 32x11.5x15. Probably one of the best M/T’s you can get that no one knows about. Really good road manners given the level of offroad performance. They weren’t too much more $$$ over the Patagonia’s when I was looking too.
