I had the federals on the Jeep, 11,000 kays resulted in 60-70% wear measured with a vernier not guessed. I do have an auto locker though and towed the caravan on them once. Noise is bad but not the worst I've had, supsingly road traction is good and not lots of tread squirm.
I had KM3s on the Triton for the last month or 2 before selling and tore massive chunks off them on the first trip, this has been reported by others but not sure if much has changed the last 2 years. Noise was OK considering, on road grip was good but they are soft so life may have been bad ill never know.
I'm on my 4th set of tyres in 18 months now, I've made quite a few setup changes on the car during the build and now run hankook rt03. I called them an aggressive all terrain rather than outright mud terrain, I've driven them in a few different places including the high country and even during the river crossings and the very steep climbs and muddy exits I didn't hear or feel them slip even once they do seem to clear very well. Road performance is good turn in his sharp and rain hasn't been an issue although I haven't spent hours and hours driving in the rain, in my 32 inch size they are noisiest at around 80 and actually better at around 100 but the diameter will make a difference in your car.
With the federals I drove them through toolangi during winter in all the mud muck and Clay I've driven them in the Portland sand dunes and I've had them in the high country and they weren't an issue anywhere, very surprised for such a cheap tyre although they're not cheap when you look at them from a wear vs cost perspective.
The photo below was Toolangi the month I bought the car when it was completely stock other than tyres and bullbar you can see they are still clearing themselves even in that slop.
