Hi Steve:

Did it shake prior to the new tires?

Funny thing, I just bought some 18 inch BMW Parallel M wheel from "The Wheel Exchange"

I took my new replica wheels to my local tire store in my town, and their "after high school wheel tech" tried to balance my new wheels/tires, and used their new Hunter GSP 9700 machine on my wheel/tire, and my God when I test drove it, my new E60 rode rough, and I was very disappointed!

But the tire store general manager saw the problem, and did the right thing, and took my 04 BMW 530i to the local Import shop in my community with a former BMW mechanic/tech/manager, and he used their SONAR Wheel balancer, and that was all I needed, my car has never ran smoother, and my Local tire store manager even picked up the tab for me. (At first I thought too it might had been my new replicas, but it wasn't them, because they were tested for roundness, etc and they were perfectly round).


In conclusion: You might want to try to find a BMW import store with a SONAR Wheel Balancer and give it a try, (keep in mind this might not solve your problem, so "wheel and deal" with the manager at the BMW import shop you choose, and SONAR Balancing should not cost you over $17.50 per wheel), I kind of believe might solve your shaking problem, beings it just started when you installed your new clones wheels, (They will test the wheel for perfect roundness when their balancing, and should be able to tell you if your clones are perfectly round or not, also did your new clone wheels need hub centric rings?).

I wish you the best....and be sure to stay in touch....and keep me posted.

PS,
What Year and Model BMW is yours? (Those M5 wheels look great, I came real close getting those instead of my Parallel Ms)

Mine also came from the same shop...Thanks so much for the detailed answer...I had them balanced twice that was a waste of money. I'll look for a shop that has the SONAR ..
Will get back to you on the out come...once more thanks much

==================================================
Steve:

I am just curious. Did your wheels come from Nathan at "The Wheel Exchange" already mounted, balanced with tires?

Or did you buy your replica/clone wheels and had the tires installed and balanced on your M5's wheels at your local tire shop?

Steve:

Did you ever get your wheel balancing problem resolved? If not,
the below research on: SONAR Balancing might can helped you???

"1. Test Drive
Test drive the vehicle and determine if the vibration is being generated from the front or rear. Determine if it is occurring at cruise speed, during lane changes, etc.. Most vibrations are caused by tires and wheels and are the result of either an imbalance or an out of round condition.


2. Measuring Runout
If conventional balancing has been tried, the tire and wheel must be measured for both radial and lateral rubout. This can be done electronically with the F99 Sonar Balancer or with the Beissbarth manual runout gauge.

• Optimizing

Runout measurements determine whether tire and wheel meet manufacture's specifications for uniformity. High spots are marked on tire and wheel and tire/wheel assembly is remounted for optimal uniformity. Tire and wheel assembly, are now re-balanced using proper balancer mode.

• Vibration Still There

Optimizing will not solve all vibrations. Test driving the vehicle may reveal that the vibration is still present and further steps are needed. If tire or wheel replacement is not demanded because of out of round conditions, the tire can be trued or they can be balanced on the vehicle.

• Truing The Tire

A tire/wheel assembly can be out of round for 3 reasons:

• Out of round tire
• Out of round wheel
• Mounting error
• A combination of all

Truing the tire removes the "high rubber" which causes vibration and also accelerates the wear of the ":low rubber". It is a proper procedure when guidelines are followed.

• Balancing On The Vehicle

Another effective solution when conventional methods fail is to balance the assemblies on the vehicle using the Beissbarth MT 600 Computer Balancer. This system uses modern technology to compensate for any imbalance not caused by the tire or wheel, This "finish" balancer is widely used in Europe to insure the smoothest ride possible.

Fact:

On today's lighter vehicles with rigid tires and suspensions, vibration problems are more prevalent than ever. This problem presents a profit opportunity for the service center which arms itself with the proper knowledge and equipment to diagnose and solve these complaints.

Hello Steve,
I ran across your problem and I had to register to tell you the solution.It drove me crazy with my 88 528.
It's the upper control arm bushings......... They wear out very fast for some reason. I installed new Dynan (not sure of spelling) bushings and ...gone. Even braking going down hill? Sound familiar.
Email me if you have any furthr questions.
