This was more of an issue of my truck shaking violently at 65+ mph. I knew I was going to have a rougher ride with 33" ATs than I had with smaller Michelin Defenders, and I could live with a rougher ride if it didn't feel like the truck was going to come apart on me. Love the way the KO2s look but didn't get a chance to test them in the mud. Hopefully the Open Country ATIIs will look as good.
I installed ATII’s on my new ride and they are smooth as glass. Haven’t hit the dirt with them but they look as aggressive or maybe more so than the KO2s.
