Wheel Vibrations?

I bought a set of used OEM 19" M6 wheels and put new tires on them when I purchased my 2006 E64. Noticed immediately that the wheels seemed out of balance at various speeds. Balanced them again to no avail. Took them to Alloy wheel repair and they indicated that there were little bends in them. Used the hydraulic jack and took the bend out. Lasted 20 miles then vibrations returned. Took them to Turbax of Miami. They trued them up and refinished them. They looked brand new. Noticed 3 rows of wheel weights on the one wheel. Put wheels on and vibration was still there but about 1/2 of what is was before. Full vibration was back within a day. Turbax is going to give it another go. My question, is there anything else that would cause the wheels to feel out of balance other than the wheels or tires? I feel the vibration in both the steering wheel and the seat of my pants. If I have a drink in the holder it vibrates while I am driving. It is driving me crazy! If I had to guess as to what was wrong is seems as if the wheel bends have a memory and that when they straighten them that the metal just goes back to where it has been previously to the repair. Taking my wheels into Turbax on the 29th and hopefully they can fix them for good this time.

Although it does sound like you have some type of bend in the rim, I had a high speed vibration issue on my six that a couple different shops could not rectify a couple of years ago. I finally went to a high- end shop that does "on-car" high speed balancing (vs most shops that balance in a machine off car). It worked like a charm and I've bought all my tires from them ever since... The shop is Butler but I believe they are only in the Atlanta area.

It sounds like that maybe one wheel might not be true. I would have them install the wheel on their machine, & have them check it for runout. If the runout is less than 2 thousands, you should be good to go. Have them check the runout in several places on the wheel. The best balancing machine available currently, is the Ground Force balancing machine. I would ask to have all 4 wheels checked. If they all check ok, start checking your suspension for damaged parts.

Good Luck!

Thanks for the insight guys. I am taking them back to Turbax on Wednesday. If they are still not right I will try to find someone that can balance them on the car.

Has anyone road force balanced them? The road force measures the runout of the tire and can determine an out of round tire

I know a freind that has access to one. He says it will compensate for the balance problems. compensating for run out, might be a different problem. It is important to true the wheel 1st, to eliminate other problems.
