I find that tire noise, like wind noise, is really individual person dependent. To me, my KO2s are pretty much silent. And I hear little to no wind noise in any of my vehicles. But put me in a car with even the slightest rattle and it will drive me nuts (which is why I just can’t spend much time in Big 3 SUVs) whereas the owner might not hear the rattle at all. Long way to say ‘your mileage may vary’.
