That's great news! Can you share a picture of the repair order or provide a summary of the parts and process used so I can explain it to my service advisor?

Also, what % of the sound would you say has been reduced? Is it something you'd now have to listen for to hear it or is the sound still hard to ignore?

Thanks!

Before, you could hear it over the radio at a normal level.

Now, the hollow noise is still there. Music at normal volume covers up the noise. On some stretches of concrete pavement, there is some elevated noise but its not constant and annoying like it was before.

Thanks. Any chance you can share the repair order so I can show my SA what needs to be done?

Also do you know if there's a way for me to check if counterweights were installed on the control arms from the factory?

Spoke to BMW... shareyourthoughts@bmwusa.com

So I had a call with BMW NA, with the Customer Experience team and filed a report about my car and this thread. I took the opportunity to share THIS Topic and link with them yesterday. They said they are unaware of the issue and would open up a claim. I would SUGGEST that everyone with this issue send an email with this Thread Link to shareyourthoughts@bmwusa.com and ask to have it forwarded to Kylie and Bernadette Q. Maybe they will pay attention as more people call it out. Here is the email reply I received today.

@palmerman

Here's the response I got back... smh


While we are able to assist with features and technology within your vehicle, we are not trained in a mechanical capacity. Your local BMW center has technicians that are able to better assist you with your tire noise concerns. I regret any inconvenience this may cause. Should you need to access a list of our authorized BMW centers, please visit our website at: www.bmwusa.com, and select "Dealer Locator."

I thought i read somewhere that the X5 should come with specific counterweights installed depending on what size wheel option the car was built with (20,21,22")

You referring to counterweights on the control arms? Do you know if I could easily check to see if mine has these installed and where I would look?

There should be. We need someone to take a few quick phone pics to document this for the forum.

I took delivery of my 40i yesterday, riding on 22s with contis and M-sport adaptive suspension.

Could not discern any noticeable noise from the tires or suspension, and I tried a variety of roads and speeds today.

Interesting. Thanks for sharing.

Someone pls help us with how to check if there are counterweights on our cars or not? I'm really hoping it's a simple fix.

It's bolted onto the front control arm (not the front thrust arm).

I'll try and post a part # this week.

I know a lot of us are curious if this will solve our issue so we appreciate it!

Executive Office Response

A BMW employee, Chris, from the Executive Offices in New Jersey HQ called me informing me my "case" had been sent up to him. We had a great phone call yesterday. I informed him about the "humming" in my new X5 on the 22" rims and about this thread about the issue. We agreed it would be great to figure this out for me and for everyone else. So to that end, he is reaching out to Rusnak service manager to have him call me to get the car in for a look. COVID is not helping though, as I am not sure if we can test drive the car together. My thought is to have them swap all 4 rims for 21" and go for a spin. Also have them look for the counterweights and see if that is an issue. Open to any other questions or suggestions...from the group. I'll keep you posted, but the good news is we have the attention of BMW USA at the highest levels it appears.

Thanks for the update. As I mentioned earlier in the thread, I was able to drive a loaner that had 21" run flats and the sound was about 1/3 to 1/2 of mine, which was surprising given they were run flats. I would be very satisfied with this level of sound on my car. I was also able to drive another car with the same 22" wheels and tires as mine and the sound was pretty similar, which was discouraging.

At this point, I'm hoping that the counterweight is the solution for the issue at this point, but let us know what you find out. Thanks again

Is this just an issue with 22" wheels and tires on the X5 or is this also an issue with the X7 as well?

I would think so because both have the same running gear.

Any chance we can score some pictures, part numbers or work orders to share with BMW when I get my car into the shop next week?

Would be much appreciated!

The part no is 31-10-6-884-584. It is the same for the left and right.

I would bet real money if you had foam injected in the tires like other luxury cars like the Audi S8, the droning would almost completely go away. Switching size of wheels would also make a huge difference. There is a “x factor” going on in these wheel,tire, road surface combo. It is fixable if we find the main source. The local tech probably has no idea how frequencies work together. I know BMW knows all about this and what it takes to reduce it.
Taking my X5 into Rusnak BMW next week. Spoke with service manager who received a call from BMW HQ in New Jersey requesting to see the car. Apparently BMW USA is sending over an engineer to the dealer to go thru the car. Going to compile a bunch of notes from this site to hand printed to them, to show I am not alone. I think the note above is particularly interesting and could send them down the right path. Please list any questions or thoughts you may have for me to submit when I drop the car for a few days. We definitely have BMW NA attention at the highest levels. Thanks.

After the counterweights...the noise seemed normal. Not gone but wouldn't expect that from 22" wheels.
