 Yea, so as you know I recently got my rims and had them put on by my local mechanic and balanced. Well, unfortunately at speeds higher than 60mph, my steering wheel vibrates badly from the poor balancing. So, I take it back and they still can't correct it.

They refer me to another place called Tire World, whom has a road force balancer. This is apparently the end all machine when it comes to balancing stubborn wheels. They said it starts at $60.

I'm just wondering if anyone else has had their problems solved by this new machine.

I found a link with some information on it.

 Has the local mechanic refunded your money for failing to do the job?

I was told the same thing by the Tire Kingdom here in Houston. They directed me to a place with that Road Force Balancer. But, I actually brought it back to the NTB when the bald-headed mexican guy was there. Because that son-of-a-gun can balance a tire. When he does it, I can ride 118mph with minimal vibration.

 Minimal? not good enough for me .... I've had my 3800 lb. accord sedan at 137 with no vibration whatsoever!

 A Road Force Balancer will measure the Lbs/inch of pressure that is caused by non-perfect tire/wheel combos. If the tire/wheel combo is not "round" it will create a force that wants to lift the vehicle and lower the vehicle as it rotates. In most cases a quality tire and wheel should not need to be RF balanced. It seems that the lower or off brand tires need this more than others. To keep it simple, the machine will measure the high and low spots on the tires tread area, and do the same on the wheel. Then it will tell you to take the tire back off the wheel and rotate the tire until the high part is lined up with the low part of the wheel. This will help to make the tire/wheel combo more true or "round". My first question to you would be weather or not the tire has a "hop" while spinning on the balancer. If you cannot see a notable "hop" while the tires are spinning on the standard balancer, you will most likely not need to worry about that. If only one tire has this issue, I would look to see how much weight it required. If it is notably more than the other tires, The thing to do is return the tire for warranty under MFG defect for "out of round". If only subtle "hop" is noticed, I would not worry about it. Go ahead and RF balance the tires. Keep in mind, if you have a bent rim, it will make never be right.

I hope this helps.
Good Luck.

P.S. I have never RF balanced any of my tires and I have been well over 100mph with no vibes.

 Did you keep the same tires or get new ones? Were they a cheaper brand? Sounds like you may have just got a low quality wheel, and that is why you are having the problem. A good, quality wheel/tire combo really shouldn't require a road force balance. A dynamic balance on a calibrated machine should take care of it.

 sounds like they didn't put enough weights on. take it to another place to have them balanced.

That's what I was thinking. They are $135 rims on my stock tires. I think the vibration is only coming from one wheel in the front. Can't really tell though. The new tire place will try their dynamic balancer first and if it doesn't work then RF,

If the wheel needs 5 oz. in one spot, it will balance better with 5-1 oz weights spaced around the spot rather than a single heavier weight.

 Putting used tires on new rims can also cause a vibration. When you break the bead down on the old rims, it won't sit the same on the new rims. If the rims are wider than the stock ones (7.5"+ rather than 7") that will cause the tire to shift slightly with speed and load.

Also, did they put the same tire back on the new rim on the same position of the car the tire came off of? If not, then you are getting the vibration from some radial pull or choppiness of the tires due to not being in the correct position on the car.


Complaining is futile when you supported the victory.

I hope they were smart enough to do that
