The KO2 just got replaced by the KO3 a few months ago. I ran the original KO's on my Bronco and with 50,000 miles on them they still had half tread remaining. Can't say I ever had issues in the snow or rain back then either.
The only time I've ever hydroplaned & another time started to slip off an off ramp in a Raptor in ~200k combined miles was on KO's. And they weren't close to bald and I wasn't driving like an idiot.
