Aftermarket wheels vibration

I’m looking for a recommendation. I purchased a set of after market wheels last year. “ Gear Alloy MB12” 20inch. After wheels were installed I noticed some vibration around 55 – 75mph. I was told to install a set of hub centric rings.. 106 – 108mm, did that! Didn’t fix problem.. I was recently told tires were bad, just replaced with Kuhmo tires and which were balanced on a Hunter Roadforce 9700 balancer. Vibration was reduced but still there, any suggestions..

 

i heard that usually if you dont have anything in your bed that your ride will be a bit bumpy cause it jumps in the rear a bit
but im not really sure

 

Are you using conical bulge lug nuts? If so, try the Extended Thread version... Here's a link... http://www.gorilla-auto.com/lug.nuts.page_08 The ones you want are on the BOTTOM RIGHT of the page. 41138ET

 

sounds like you need to Install different hub-centric rings

 

Thanks for all the feedback, I'll start by replacing the lugnuts the "Extended Thread version" DR RabbitfurHead recommended

 

Hi Everyone,
I finally got the vibration issue resolved and here’s how… I replaced the lugs with the extended thread version as recommended by DR RabbitfurHead. I also had to replace the front rotors, the originals were slightly warped. The truck rides like new...
Now I can finally enjoy driving my truck again….

Thanks for all your help!!

 

I'm glad you seem to have your problem fixed. But, I'm confused about something here.....one thing I've learned recently about our wheels is that Tacoma wheels are "non hubcentric". They use acorn style lugnuts to center the wheel on the hub, not the center bore fitting tight on the hub itself. Chevy trucks are hubcentric which is different and does center the wheel directly on the hub. So I'm wondering if you should have hubcentric rings?

 

Glad to hear you have everything figured out and your truck is running well.

Just for the record, Tacoma wheels from the factory are hub centric. Any aftermarket wheel made specifically for the Tacoma are also hub centric. Toyota uses a 106mm OD hub from the factory (not sure of the tolerances).

Almost all aftermarket wheels are lug centric. They are not made solely for the Tacoma, rather they are made to fit many different makes and models of trucks. Many of the aftermarket wheels that fit our trucks have a 108mm ID bore (that fits very loosely over our factory hub). The lug centric wheels need lug nuts to center the wheel to the lug posts on the hub. This is the next best thing to a hub centric wheel.

Some companies make a plastic donut that adapts the smaller hub OD to the larger hub bore ID of the wheel. The problem with our trucks is that a 1mm thick plastic wall (radial) is just too small to do the job (it would break) so we need the acorn style lug nuts.

I also recommend using a Hunter, road force balancing machine to balance the tires to make 100% sure you don't have vibration problems. Using the right lug nuts and the right balancing job pretty much guarantees you won't have any problems (unless the wheels or tires are just hosed from the manufacturer).

 

Hey Dr Rabbit, thanks for setting the record straight on that.

 

You are correct… In addition to the lugs and rotor replacement I originally had a set of hub centric rings.. 106 – 108mm installed… (plastic) and they do break very easily… The wheel and tires were originally balanced with a Hunter Roadforce 9700 series Balancer…

 

I've tried all those things, except for the rings. I've had them road force balanced andit worked frine for a week now it shakes again. very frustrating. Any other ideas? Also it is very inconsistant. Sometimes shake sometimes smooth. can't figure it out. I have the extended threaded lugs ffrom Wheelers Offroad. So it's not the lugs
