My nittos on my 80 performed very well in the snow despite some folks having different experiences. That is a consideration for me. I’m in Northern Virginia and we can get a good bit. I’ll have to dig up some reviews on their snow performance.
I have about 10K on my KM3s and noise is not a factor compared to the wind noise of the FJC in general. This is my daily driver and I had KO2s on before. I didn't like the wet weather handling of the all terrains. These KM3s laugh at standing water.
