So as I posted a few weeks ago, I got a new set of staggered 20x10 and 20.8.5 chrome bullitt rims and TOYO PROXY 4 tires from CruizinConcepts.com. Well when I got them, the car was fiercely vibrating and shaking when I drove so I figured one or more of the wheels weren't balanced. I took the car to the tire place and I was correct, so the guy did a roadforce balancing job, as well as removed the tabs from the stock rotors on all four of them and the car drove perfectly, just like it did with the stock wheels. Well over the last few days, I noticed the car shaking and vibrating again and its been getting worse, today it's unbearable. I checked the PSIs which are fine and retightened the lug nuts (which were already still tight) so I don't think that's the problem. I'm bringing the car BACK to the tire shop again tomorrow, but in the mean time, anyone have any idea what I can do to fix this? I REALLY don't wanna have to pay for ANOTHER balancing job.

THANKS!

 

you could have lost a wheel weight

 

Is there any way they could simply look at the wheel and know that without actually re-balancing all four wheels?

 

You can check yourself, go look on the inside of rim (usually they use the tape on weights for balancing) and see if the weights could have came off a wheel. You should be able to see where the weights were stuck on the wheel if they came loose and fell off.

 

i have the same problem, as soon as i put my 20's on i was experiencing vibrating at about 60mph. took it to where i got them mounted and they rebalanced them. now i experience this vibrating at about 50mph, i didn't even bother to take it back. Seeing as i never cruise at 50 i just learned to live with it. the vibrating only occurs from 50 to 55 after that its pretty stable.

 

Yup my friend lost a wheel weight but he really herd it when it came off, bouncing on his inner rim..

Other problem could be the alignment is off

 

20's are hard to balance.

 

you might need centering rings - small, plastic rings that go around the hub and fill any gap that results from an am wheel. i know i use em for both sets of my wheels and they made a big difference in eliminating all vibration for me.

 

yeah, I would check to see if you slung a weight or not (seeing the the tire pressure & lugs were ok).

as far as installing hub rings to make the wheels hub-centric, I am a firm believer in them, but seeing as you didn't have any problems right after you left the wheel shop, I don't think that's your problem..

 

So where can I get these hubcentric rings from? And are there specific sizes to get or just like ones for a 20" wheel?
