i just put on 18" rims with hankook tires. and now my car has a slight shaking to it between 60 mph and 70 mph. what can i do? is it the balancing of the tires is wrong or is it the size of the rim? or size of the tire?

 

Probably need to get them balanced with a really good machine. That equals a Hunter Roadforce balancing system (click here for more info & a dealer locator for finding a Hunter equipped garage neear you). Has solved MANY a problem like yours.

Just in case, what size wheels & tires are you running? Improper sizing will not cause vibration; insteat you'd see some sort of rubbing.

 

Double check that you have hubrings installed as well. These are small rings that allow the generic aftermarket wheel to fit the Audi specific hub.

 

Same thing happend to me when I put 18s on my 99....i had them rebalanced and it helped some but still has some shimmy around 60-70. What are these hub rings your are talking about mike?

 

YEAH WHERE CAN I FIND THESE HUBRINGS AND HOW DO I KNOW IF I HAVE THEM INSTALLED?

 

Now Ray... I thought we got past this yelling thing.

They're called hubcentric rings. They need to be matched between the Audi hub and the wheel in question. If you don't have them, you'd need to get them from the wheel manufacturer or one of their dealers.

 

I have a 00 A6 2.7T with eh 6 speed manual and the sport package and stock rims. I want to Les Schwab which does have the GSP9700 and I still have vibration between 60-70. Is there anything else that could cause is or are they not useing the machine correctly?

 

Vibration through the wheel at a particularl speed is usually caused by an imbalance with a wheel(s). If a hunter system doesn't pick it up, I'm not sure what will. Have you asked them for the printout from the Hunter system? It will reveal, numerically, the balance of each wheel.

Otherwise, let's hope somebody else has something to offer on this.

Good luck.

 

i used the hunter wheel balancer. before i used it only the steering wheel shook between 60-70. after i used the hunter now the steering wheel doesnt shake at all but the whole car shakes between 60 and 75. after 75 its all good. what do i doooooooooooooooo?

 

Ya got me stumped. I'll be watching this one though, because I've got a good friend who has the same problem. With any luck, somebody else on the forum can help us out...
