I am running the KM2 at the moment. Work great in the sand and mud here in Florida. They are fairly quiet for an agressive tire at speed. Not a fan of the highway performance yet- still chasing some vibration that's more than I find acceptable above 60 mph. If I get that solved they'll be great.
I have KO's on my truck that have made it 45k miles with a heavy foot. Great highway tire and OK in sand, but almost worthless in the mud.
In the past I've had good luck with Pro Comps. Balanced well and rode smooth as glass.
