I went through this delema and here is what i got from my research...
I was looking for a 31"x10.5" 15" so thats where the prices came from...
Toyo M/T- 40,000 $200 on sale normally 250 (winner)
BFG KM2- 20,000 $190
BFG KO- 45,000 $195 (not enough deep snow performance as i have a half mile of pushing snow with my bumper sometimes)
Goodyear Bighorn- 25,000 $175 on sale normally 200
Cooper Discovery- 20,000 $180 (i have a friend that only has 10,000 and is starting to look for new ones
Super Swamper TSL- 15-20,000 $165
Dynapro M/T- 25,000 $185
The Toyo's one simply for the fact they meet my demands to get in to my cabin and they are the quietest M/T I have ever rode on. They wear incredibly. My dad put 55,000 miles on his 6.0 on Toyo M/T
