Siping does make a difference on slick rock. Really.
May I never see the day.
My experience with the BFG MT is that the center lugs can clog up in thick goo, but the large shoulder lugs (apparently a new feature on the KM version circa 2002) generally clear themselves enough to maintain forward traction. Still, they ain't no boggers.
How did you find the trxus for tread wear and street manners compared to the other two?
