Toyo Open Country AT III 35x12.5x17. A little more aggressive than the KO2's.
So far, they work really well. As they've got broken in, they have gotten louder, but nothing annoying. I lik'em!and two decades more modern!! hope they work out well, i have these on my radar for the ZR2 next round. of course in a 33.3x10'ish size..!
