Short YouTube transcript of Mike Melton demonstrating why BFGoodrich All-Terrain KO3 tires frequently cause vibration and are difficult to balance. He uses a tread depth gauge and a road-force balancer (applying 1,200 lbs) to show a high force reading (63 lbs predicted to 46) and warns viewers not to buy these tires.
This guy came to us because he could not find nobody to balance these tires out. These right Here are the BFGoodrich All Terrain KO3s. These things are notorious for always vibrating. I tell people, do not buy these tires. Let me show you. Now, you see there's no feathering whatsoever in this tire, right? No feathering. We're going to use a tread nib gauge, right? Here we go. Where's our tread depth? We're at 9:32, right? So it's still a really good tire. Now we got it set on lt. Road force is on. Let's bounce this thing out and show you exactly why you don't buy these tires. All right, now we got that tire rolling. Now, I'm not sure if you said, but it's hopping pretty good. That tire is. The wheel is perfectly straight. Roller's about to come down. What this roller does, it puts 1200 pounds of force on this tire. That checks for anything that's going to cause the vibration, whether it be in the wheel or tire assembly rollers coming off. Look at this. Right now it's at 30. I mean, 63 pounds of force predicts us down to 46. So you should not be over 35. We're at 63. Do not buy these tires. You're always going to have issues out of these tires.
