When should the KO2 get replaced?

[Fireguy144]

I have 50K on original KO2's. Noisy. Not much wet traction. No crawling on them. If I can get around Chicago this fall, will replace them in the spring. Otherwise earlier!

Hello ...
I was curious as to what PSI everyone was running there KO2 at. My truck is fairly new and I run them at 38 psi ... is that OK??

Mine lasted to 30k, just put on Nitto Ridge Grapplers , awesome tire, quitter and smoother ride

what about the
Nitto Terra Grappler G2 ?

Not a lot of off road so mine lasted 60k.

Regardless of the mileage...

When the tread is gone, replace them. And yes the noise increases when the tread lowers, and its very noticable now; for me at least.

My last set lasted 20k. If you off road them at all they come apart. My gen 1 had better life 37k on the originals. Gen 2 just eats them.

classic over inflation on the left tire

Yeah, that's part of the story bud.
