This is interesting.
Seems the one way to tell if you like them is to buy them and drive them.
I think the KO2’s are quiet. I have Coopers (I think Discoverers), on my Xterra and the GMC. I hear them a little in the Xterra, but a lot in my GMC. To the point I was worried about the front bearings.
I had BFG Terrain Trail or something like that on the Xterra. Couldn’t get KO2’s in that size, and there’s not room without modification for bigger tires.
I opted for the Coopers this go around. The BFG’s wore well but I think that contributed to them not doing as well in ice and snow. The Coopers have done well in ice and snow, but I’ll probably try something else next time.
