: Wobbly wheel but still balanced?

I took my front wheels in to get balanced and they had me come out into the shop to show me that one of the wheels wobbles when its on the balancer, but they said it was balanced. Is that right? The wheels are about a year old with maybe 600-800 miles on them. No way could I have damaged them. I never ran them out of air or drove over a curb or anything. When I first had them mounted, the place never mentioned anything to me, but I'm guessing they came from the factory like this. These are $300 TTII's! The reason I took them in today was because of the 60mph vibration my car has always had. Could this be the cause? Whats my options? Thanks.

ae,
A wheel can be bent and still be balanced perfectly when spun on the balancer. The bend can certainly cause a vibration though.

The bend actually causes the wheel to move in and out relative to the vertical plane. Out of balance causes it to move up and down relative to the horizontal plane.

Will definately cause a vibration. Same idea as a warped brake rotor when you hit the brakes.

it should be replaced. tire is going to wear prematurely and stress other components.

I had an issue with my 70 SS wheels, Wobble!!!!!!!!!!!!!
I got into my 1970 Chevy Shop manual. Chevrolet allows 1/16" of an inch run-out. Any more replace the wheel. Or you may stress out other parts and have a major accident. My two cents.

OK. I'm sure my warranty has expired, but I'm contacting AR anyways. I'm sure the wheel came like this from the factory. Whats interesting, is in Summit Racings catalog, they recommend you have them road force test all wheels in order to prevent exactly what just happened to me. Here's some advice for everyone. If you buy new wheels. Get them road force tested when you have them mounted. Regular balancing won't catch bent or mishapen wheels apparently.

Go here: http://www.gsp9700.com . Click the image "Find a GSP9700 Near You" It does the road force balancing. Be sure to specifically state to the tire shop you want your wheels balanced on the Hunter GSP9700. Most tire shops have multiple wheel balancing machines. At America's Tire (Discount Tire in some places), they charge $5.00 wheel extra for the road force balancing (they call it "road matching" or something like that). Only way to fly is road force balancing. Smooth as glass :)

Cool. I found a place about a mile from where I work. I'm going to stop by tomorrow and see if they can throw the 2 fronts on there and at least let me know if I need to replace either of them. Thanks.
