Whats up guys, I got my wheels road forced balanced to try and fix steering wheel vibration at around 60 mph, fixed the problem at this speed, but now i noticed vibration around 80-90mph. The tire shop installed hub rings as well, took it back so that they could re-balance them and still feel it a bit.

Can it be the quality of the tires that is causing the vibration? I have 18's with Nankang tires, I know these aren't the best tires around but they are basically new.

On a previous thread I stated that I couldn't put the caps on the front rims because the spindle is too long. Does anyone now where i can purchase a cap about 2 1/4" that will fit these rims?

It is very possible it's the tires. Don't want to hurt your feelings but Nankang tires are crap. If you have the funds, replace the POS tires you have and buy something else. A lot of people on here run Toyos, Falkens, Nittos, etc. You don't have to spend an arm and a leg to get good tires.

 

Had the same problem bad on my GS when I put 19s on. It ended up being the alignment. Worn bushings can also cause this. If your balance is on and you have hub centric rings then its time to take a look at other areas as well. Low profile tires always magnify problems that don't always show up on stock wheels and tires. It could be flat spotted tires or something stupid but looking everything over is your best bet to keep from throwing money at it.

 

Yea i know nankangs are not the best tires, maybe I'll purchase two new tires for the fronts for now. Is there a difference in hub rings? I know hub rings were installed, but I keep hearing you guys mention centric rings.
Remember not feeling any vibration at all with factory wheels on, would go over 100mph and felt nothing.

 

All rings do the same job. They just need to be the right size. If they are on then they fit. The reason you don't get it with the factory wheel and tire set on is that they tend to soak up vibs due to the thicker tire and they are not as heavy in most cases. Like I said in my above post. I would look at the other suspension parts. Start at the alignment and work your way to the bushings. It only takes one. Even a bad shock will cause this. Just a little off will give you the wobbles big time. If you got a good road force balance then you should not have a problem with the wheel and tire combo. Then again it could be that you got a bad balance too. Happens even with the best equipment. Those fancy machines are only as good as the operator.

You could swap the rears to the front and see if you still have the problem after a test drive. If so then I am betting there is another problem and its not your wheel and tire set up. I have the same problem with my G but know the tires need to be balanced and the compression rods are worn. Both will cause this problem. These are the type of problems you can throw all kinds of money at until you finally get the one part replaced that fixes it. Make sure you use qualified techs and they can trouble shoot without swapping parts to chase a problem.

 

Hey albert, not to change the subject but how much did you pay to paint your sideskirts, if you don't mind me asking. Nice looking ride!

 

+1 on the suspension theory. Check the shocks.
