Mike Melton diagnoses wheel vibration on a Ford F-150 with Pirelli Scorpion AT Plus tires using a Road Force balancer. Static balancing fails on hub-centric wheels, so he uses dual-plane balancing with weights on both sides, reducing vibration force from several pounds to four.
This guy came in here with his F-150, said he cannot get the vibration out of these wheels and tires. Well, they're not the cheapest stuff. He's got the Pirelli Scorpion AT Plus on there, which is a really good tire. He's got the Fuel wheels and the wheels are hub-centric. So you're not going to need hub rings for any kind of vibration issues. All right, we got the first one set up. Let's go ahead and see how this one's going. All right, now let's go ahead and spin it, see what's going on with this thing. All right. One thing I already see wrong is a static balance the wheel. You cannot static balance these wheels. They will vibrate. All right, we got all the weight off. Let's go ahead and see how it comes out. We're gonna Road Force here in a second. All right, the Road Force is coming down, putting 1,200 pounds of force, simulating it being driven on the vehicle. We're gonna call— we're gonna see any kind of vibrations before it goes on the truck. All right, now it's coming off. Now look, this is dual plane. That means you're gonna have a weight here on the inside and one right here on the outside. Now you see before where they had the 08s, you don't stick it there, put it over here., and then the other one we're gonna put a clip on right here. So now with that, this thing's only got 4 pounds of force. So of course, with it being an ounce off and not balanced right, it's going to vibrate.
