Since you asked, I am running the new Falken Wildpeak A/T3W's. And to be honest, I dont know if they are superior. What I do know, is they are significantly cheaper (about -$400 total) and run very quiet, along with having a very similar design to the KO2s. You would be hard pressed to find a user that has seen over 30k on those tires, so I am hoping they run well. But for the price, I couldnt say no.
Guys, I am not saying your tires are shit. In fact, I really like the tire. Like I said, I almost bought a set. But, I have a close friend that does the fleet maintenance for Virginia DOT trucks, and has repeatedly said that the KO2s they run on them are meticulously maintained, and still show significant wear at the 25-30k marks. So I was sharing that opinion. For future reference, now I know that if you arent on the BFG KO2 bandwagon, you better not post lol
But to say they are the "highest rated" is just as much an opinion as me saying they are way overpriced in reference to their performance against other brands. If I were to pick the tire I thought to be superior, without regard for price, I would choose the Toyo AT2. It is almost impossible to find a bad review about them, and I have personally seen them go nearly 70k miles with life left.
