Customer Reviews
I replaced the front two KO2s on my Ram 3500 dually diesel truck with KO3s. The KO2s only had 13k miles on them when I replaced them due to them being uneven, shiming, and they we're making alot of noise. I'm hoping these do not do the same! The rears have 18k and are wearing evenly and are still quiet. I do haul a truck camper weighing approx 5k on nearly all of these miles.
These BF Goodrich KO3s are way quieter than the original Goodyears on my Bronco Badlands Sasquatch. Expensive, but worth it due to the significantly reduced noise.
After multiple sets of KO2’s, I was initially worried about the balancing issues mentioned in many KO3 reviews. My sales rep assured me that the issue had been with early production tires and that BFG had resolved the problem. I’ve had no vibration and the KO3’s are noticeably quieter than KO2’s.
Good looking tires
