My experiences with A/Ts vs KM2s.
They are louder than the A/Ts but not like Super Swamper loud though. Handling is much the same even with running at 37psi vs 44psi in the A/Ts maybe a bit more roll but not bad to be pushed hard on or off road. They don't throw as much little dirt and gravel up to sand-blast paint off like the A/Ts but when they do throw, they throw ROCKS, and they chuck mud like a mud tire. I got about 17143 miles out of of my A/Ts, tire spinning and sliding running the truck like a rally car. The KM2s now have about 12746 miles and have 12/32" remaining, originally 17/32". The KM2s do not seem to have a tendency to chunk out as much as the A/Ts, my primary roads are volcanic cinders that chew tire tread to shreds. About the only negative thing is that they rumble and vibrate the truck at very slow speeds (1-5mph) on pavement, takes a while to get used to. Light fluffy deep snow 20", much better than A/Ts, I broke open a 11 mile stretch with no traction problems did overheat the truck from blocked radiator. Heavy wet snow 10", dug through but was squirrely, I never would have even tried with the A/Ts. Not a nearly as good on ice and packed snow as the A/Ts but tolerable, just slow down more. Haven't used either in deep gooie mud, but light mud is far far far better than the A/Ts.
