kinda funny, in the snow we ran mtr's at 1-2 pounds with no bead locks, never a problem. Friend lost a bfg inner bead with outter beadlocks first time out at 5 psi.
Yeah, MTRs are a bad ass tire. I usualy run BFG muds but i have neve run those under 8 psi. I will most likely get a set of mtrs when it comes time to buy new tires because everyone i know that has them swears by em. Hell I practically swear by em and I have never even owned a set. Riding and wheeling with my MTR buddies was enough proof for me.
