I'm at 15k miles. Half tread. Personally these are my least favorite tires I've had on a truck. Many love them but they downright scare the hell out of me in the rain!! Soon as its starts to drizzle and roads get wet my truck goes into 4A.
Early on in first few weeks of ownership, I was just driving the speed limit 40-45 in a light rain on a typical paved 2 lane backroad. Entered a turn, thank God no one was coming, but within a split second I was pointing the opposite direction in the other lane. Did a complete 180 out of no where for no reason at all. Didn't hit throttle mid turn or anything stupid... just normal driving.
So I just chucked it up as a fluke. Then a few weeks later same thing. Rain, normal driving, entered turn and rear end broke loose and came around on me like I was on ice. But it was 80 and mid July. So at that point I started really paying attention to the driving conditions and these tires characteristics.
What i found was, on wet roads, anytime i entered a turn at a speed that created a little body roll and the road was flat (not cambered), cambered the opposite way, or had any imperfections/bumps causing the rear end to hop or lose perfect contact.... the rear end would break loose and get squirelly.
So at that point I started putting it in 4A in the rain. No more squirrely or rotating rear end mid turn since.
