Dealer found 2 cracked wheels (which they replaced) and one cad tire (also replaced). Service manager said I'm probably the only person that would have complained about the slight vibration but was surprised that I pushed him to check it. Now it's smooth as butter. Lose the spacers and don't be a poser.

You should read up on the thread…

Update : received my custom spacer (66,65mm), it fit my two set of wheel perfectly !
definitely solved the problem so happy.
nota : please read the entire thread before ask questions or suggest something

Happy to hear that you solve the issue!! I tried yesterday with custom spacers 66,6mm but didn't solve the problem…

Could you post some detailed photos on instalation process? Maybe i missed some steps…

Thx!

your spacer have 66,6mm spigot diameter, and what about the spacer bore diameter??
you juste have to install the spacer into you car hub, it should be very tight, the mine are 66,53mm and then install the wheel into the spacer, the wheel should hang itself. clean all the support with brake cleaner
one of mw wheel set bore is 66,74, so 66,6mm is too small, you should increase to 66,65

[Frenchstar-57]

advice for custom spacer : before make custom spacers you have to do few measures
each hub spigot and wheel center bore
hub spigot can be measured with a caliper BUT center bore have to use bore gages
my front spigot are 66,48mm
my rear 66,46mm
-> So i took 66,53 spacer bore
i have two set of wheel, winter wheel are 66,74 and summer wheel 66,7
-> So i took 66,65mm spacer spigot
when i installed the spacer it was perfect, no play and fit perfectly (the proof that the measures was good)
so, to be sure, do measure before spend money making custom spacer
and when you received your spacer, measure it to check if it is compliant to your requirements
AND DONT FORGET TO USE LONGER BOLT RELATED TO THE SPACER THICKNESS

Agree.

The key thing here for any custom-made spacer, or spigot shim, is to take up the radial tolerance.

Using a custom spacer shouldn't really be necessary, if we have an eccentric mount issue, but is a good, engineered solution.

The tolerance on BIMEC spacers seems perfect for the G30, my wheel doesn't fall off or rattle with bolts removed I need to actually pull it off manually and when refitting I can rotate the wheel on the hub and the holes line up exactly centred to the wheel.

Could save a lot over people having bespoke ones made.

Do you use oem BMW Wheel? if it is the case, it means that your wheel are not in high tolerance or the spacer are 66,6mm spigot diameter

spacer manufacturer do the same spacer reference for bmw audi and mercedes 5x112 66,6 that are 66,45 in reality to match 66,5, 66,56 and 66,6 Audi mercedes and Bmw wheel
it would be interesting to measure the spigot of your spacer !

I'm using original 1001i alloys so no idea why but maybe the BIMEC spacers are just closer on tolerance to the BMW measurements.

Or the special edition 1001i alloys are manufactured to better tolerances.

Sometimes I have to kick the bottom of the wheel to get them off it's that tight without bolts.

I'm running 15mm all round.

nice, good thing that you have to kick the bottom of the wheel to get them off, i think that your wheel are a small high quality production series

Hello,


I have a G31 LCI with original rims but after installing winter tires i noticed the vibration at 120km/h. ( maybe it was already there with the original summer tires, but since i live close to my work, i do not drive 120km/h a lot )

The tire shop said that everything is fine and the tires are balanced, i am ready to take it to the dealer because the problem is still there...

I have read several solutions here, but am confused what is best:
1/ mount the wheels perfectly center with a centering tool
bmw part 83302459458

2/ install 4 friction discs

3/ install custom spacers ( isn't this bad for the car ? does it replace original spacers that have too much tolerance ? )

4/ user gauger tape around the spigot

because it is a lease car i think i cannot suggest a non bmw part solution to the dealer ( like option 3 ).

What of the options above ( or a combination ) has the most chance of succes ?

Thank you in helping me solve this problem.

kind regards,
Tom.

Hello Tom, glad to read your post, you summed all my attempts(more than 30 tests) to reduce vibrations.
custom spacer is the best solution.
The two reliable solutions : change the wheel(66,56 CB wheel) or use custom spacer (66,65 lip)

appart from this, the less bad solution : 1 layer of aluminum tape 0,1mm, just one layer and no overlap.
And then carefully install the wheel and tight the wheel to 140NM.

Have you considered a software issue. As the steering can tighten or loosen due to different driving modes. Perhaps there is a software issue here that could be effecting the suspension. Also consider the drivetrain and vibrations consign from that of you can feel under the seat it could a number of things

Hey French, it seemed that 0.1mm metal tape solution worked for you. Why did you choose to install spacer?

Hi,
->with 0,1mm metal tape it reduce the vibration a lot
->with gauge tape, too, but difficult to insert properly , could twist the gauge tape, except if you use 0,05 gauge metal tape with 0,05 classic tape to maintain it around spigot
->the best result was with custom spacer, it is more reliable and vibration disappeared (in addition you must have the wheel good balanced)

[spiderman1982]

Get rid of the wheel spacers. They are known to cause problems.

[shawntech]

How are bent wheels being determined? I have a coming and going minor vibration and jitter but my wheels roadforced under 20lbs and I don't see anything unusual spinning them. Near new pzero pz4 runflats.

Anybody else having vibration issues?

mine vibrates at 1-15mph.

Anyways, just to make sure that I´m not the problem I drove the new 3 series after my trip with the brand new 520d (had driven the 3 series a couple times before). It is remarkable how much better this car is than the 5 series wrt. smootheness, stability on highway..quite impressing.

Dediced to place a new order on the 3 series (g20). Yeah, I know ..the sound insulation is not as good as the 5 series and the cabin space is not impressive etc... after all I just want a car that drives as a premium car.

Wow lol I have 3 and 5 series I think I need to keep both as I have been debating whether to sell the 3

[APMX101]

Hi g21, did you resolve your vibration issue? I have the same issue after changing my winters for summers. Except its worse as it vibrates at around 60 to 80km and worse over 100km. I have had the dealer balance (road force), and align to no avail.
