Tire/weird noise?

M2OG · 07-08-2017, 12:32 AM

Hi everyone,
Recently swapped the stock Continental tires for Pilot Sport 4s and have noticed that at exactly 3-4mph I get a noticeable "whomp whomp whomp" kind of sound, seemingly from the back of the car but thats difficult to determine. I shot a quick video to get the sound.

I can't be certain about when I started hearing it, so it might not be the tires at all. I'm posting here to see if anyone has a similar experience before I put the car on jack stands.

Thanks!

Ugh
Assuming you have a torque wrench, the simplest thing to do is to loosen the lug nuts and then re-torque them, in a crisscross pattern of course

Even if you don't, as long as you have a lug wrench to loosen them with, try re-tightening them (crisscross pattern) and see if that helps - then go get them torqued to spec.

You might just have a bad tire or they didn't balance it as well - but the noise sounded weird.

Good luck and let us know the outcome!

^ Agree, sounds like one of the wheels isn't torqued flushed to the hub.

I did the same swap, so happy I did. I have not experienced this at all. I would take the wheels off and then retorque them, its possible the sidewall is not entirely true and its causing that wobble sound so if torquing does not work I would take it back to the tire dealer and have them examine it closer. This is a sound you get with large offload tires but probably should not be common in a street tire. I would torque and then drive them for a while and then check them again.

I should note. I did bump up to 255f and 275r. But I can't imagine that being the issue. I'll report back once I have a chance to investigate further. Thanks for the reply's, I would never have thought to even need to check the torque on the wheels.

Your oversized tires are rubbing on the struts.

Might want to take a close look a the clearance of the tires and see if the inside of the tire is lightly rubbing against anything. I decided to stay with the stock size to be on the safe side. My guess is something is lightly rubbing on yours. Let us know how what it ends up being.

M2OG · 07-08-2017, 11:05 PM

yeah I agree. I did check yesterday from under the vehicle but didn't see anything remotely close to the tires. The plan is to get it on ramps and really poke around.

CSN · 07-09-2017, 09:13 AM

Im having the same sound at very slow speeds. I have had this from day one. Stock tires with no changes. I thought it was normal. Apparently not.

M2OG · 07-09-2017, 12:58 PM

So a little update. I climbed under the car again in better light and there is zero chance that the tires are rubbing on the struts as there is at least 1.5 inches clearance.

I'm starting to suspect the differential

Did you physically remove the wheels and reseat them?

Not yet, it's too damn hot out. 😭

Keep us posted. Im wanting to know what this is too.

M2OG · 07-10-2017, 09:25 PM

Little update. Re-tourqing the wheels did nothing so I brought the car into the dealer. The service advisor, shop foreman and tech all agree the sound is not normal and have spent the day trying to diagnose it with zero success. Next is a call into BMW.

Thanks for posting and for the updates. This will definitely be useful when I take mine in. Is yours a 2017?

M2OG · 07-11-2017, 11:20 PM

The noise has been isolated to the left rear. Tomorrow a new wheel bearing will be installed as it's the most suspect culprit.

Yes mine is a 2017. Took delivery in January and have approximate 3500 miles on the car.

M2OG · 07-12-2017, 05:47 PM

Another update. Looks like it wasnt the wheel bearing. The tech now suspects the dealership that did my break-in service may have used the wrong diff fluid.

Please see my recent posts in the maintenance, oil, etc... section, topic 1200 mile service. What oil did they list on your service invoice?

I had this exact sound on my 235. Turned out it was front right wheel bearing...sounded like knobby snow tires...very similar to your recording

YIKES...did they use the one that doesn't have the FM? The expensive stuff?

I'd push for a new diff...especially if you've put some miles on the car since the 1200 mile service.

A friend was nice enough to print this for me so thought I would share.
