New wheels causing vibration? Need help

[Cory619]

I have a 2004 runner with 2.85 lift in the front. For the last 5k miles have be running the stock wheels with 285/75 R17 BFG TA's. The ride was smooth. No vibration in the steering with the OEM wheels.

Because of the oversized tires, I was rubbing on the frame and UCA at full steering lock. I purchased new wheels with a -12mm offset. Now I feel a vibration in the steering wheel from 40 mph up.

I had the tires place rebalance the tires. They are balanced. Still having the same result.

Could that -12mm offset be causing the vibration since the wheel is now out further?

I'm also thinking it could be alignment?? the original alignment after the OME/5100's still had the 265/65R17's......

Thoughts/experience?

Thank you.

Are the new wheels hub centric or lug centric? Probably lug centric. There should be some plastic rings that center the wheel on the hub. Also, make sure they torque the wheels by hand, in a cross pattern. Above that, the new wheels may be out-of-round which there is nothing you can really do except replace the bad wheel(s). I would carefully watch while the wheels are on the balance machine. The lip of the wheel should stay in the same plane and not jump at all. The shop could also try spinning the tire on the wheel 180 degrees. I would also ask the shop to re-calibrate the machine before they balance your wheels. Does the shop have a Road-Force balancer? If they do, I would tell them to dynamically balance the tire/wheels on that. You can read a little more about it here:

Thanks for the response gm350reratliff. Yeah both time they balanced the two fronts they looked right. I watched. I'll have to go to a different store and go through it again. The only thing I can think of is that I have a worn out bushing and the -12 offset is aggravating it perhaps?

Or....the wheel itself is junk.

Always something :banana:

It's just your new wheels are lug centric instead of hub centric the way they should be. Have had the same issue forever lol. Make sure you have correct lug nuts(conical extended thread), also hub centering rings may help, they did on mine. The biggest difference was the tire shop balancing them with a flange adapter that goes through the lug holes instead of a cone that goes through the hub bore like normal, rides a lot better.

This ^^^

I forgot to mention the adapter. A lot of shops don't have it but it does make a lot of difference on hard to balance wheels.

"All wheels are either hub-centric or supplied with centering rings to ensure a smooth vibration free ride."

I need to go back in and inquire about the centering ring and the flange adapter. They did use extended lug nuts.

There was not any vibration prior to installing the wheels even though I was running the BFG's on stock wheels.

I did have to remove the mud flaps and adjusted the front plastic.

Thanks for the info.
