I was happy to have my factory KO2s wear out and replace them with mud terrain tires. So far I have had Toyo MTs that I had drilled and pinned with studs and siped for witner use (actually wore through the first set and puchased same again this last winter), and a set of 'summer' tires being General Grabber X3s (COVID buy very much limited my choices).
The Generals are great for overall usage, as they are a pretty mild mud tire and the sound is very similar to the stodk BFGs, with the TOYOs being great as well-the TOYOS did get louder with age.
As for the OE KO2s, never liked them, as I actually use my truck as a daily as a field guy, meaning some town, but also lots of highway and rugged off-road (not much high speed runs in sand, but lots of rocks, dessert & sage, and some primitive dirt tracks in the desert, along with mountain passes, snow, etc. The KO2's nearly left me stranded with a bed full of soil samples as a small rock lodged itself in the middle of the tread and the puncture had me high tailing it for a town with a tire shop, as I would have had to unload the bed to be able to jack it up to change out the tire.
10-ply mud terrains is all i run anymore for more than 2 decades. Work great in everything except ice, that's what the winter studs are for. I have run KO2's, KM's, KM2's, Maxxis Big Horn, Cooper MT, Goodyear MTR, General Grabber X3's, Hi Mile XTR, Firestone ATs...on everything from Ford Ranger, FS Bronco ('92 5.8L-love that thing), Jeep TJ & JK Rubicons, '18 Raptor.
