i've got the BFG Mudders and i can only say i've been pretty impressed. have about 30k on them now and probably if i pushed it could get another 30k, since they only look half worn from when i got them with about 5000 miles on them. may get mine siped for the duration of the 25-30k for the rainy months, like that really happens hear in socal but wouldn't be a bad idea, since siping is generally pretty affordable. the BFG mudders don't like water in city driving, but are fantastic when the rain on the highway is inches thick! reason why siping would be important if you're in a geographical area that gets rainfall, i.e..PNW.
i love my tires, but the toyos from what i've read and heard are supposed to be exceptional!! drawback is they are heavy, heavy MOFOs...
my next set of tires will be BFG Bajas, in either a T/A or if i get lucky, the Baja KRs... either way, they are the most bulletproof of tires in BFGs lineup!
let me also add that if you get MudTerrain tires, to make sure you DO a regular tire rotation on a 3 or 4 month schedule to get the most out of the tread AND also, if i may STRESS, to be sure to have your vehicle properly aligned for a misalignment will EASILY chew thru the tread and Mud terrain tires are notorious for developing an uneven tread once the misalignment kicks in. subsequent effect, your tires will hum and drone much louder than before getting them new, so stay on top of that!!!
