It would help to know which tire you are putting on the 17" rims as well as the load rating (SL or E, for example.) One of the reasons I went with Falken WildPeak AT4w is because it came in a size and spec that met my needs, but the KO3 did not. So, I'd pick a tire first, then find the size that most closely matches the desired diameter.
I’m leaning towards the Falkens. I was originally looking at the Toyo AT III EVs but fear they’re not the right tire for the rocks of the Rockies. I’ve always had KOs but they’re a pain to balance and I never liked their wet traction. KO3s are supposed to be better but I believe the ride will better with the Falkens.
