Humming at 75+

[Luka]

My 2013 S P85 has a noticeable humming sound when I exceed 75 mph. To be expected?

Nope. Not normal.

Car runs fine other than the 75mph+ hum. Was hoping to get more replies. I guess I'll have to go through the hassle of making a service appointment.

Not normal for my 2016 75D.

I have a similar situation with humming at speeds between 70-75. after doing A lot of digging around and not find an answer i made an appointment. After riding with the tech he agreed and later found out it was unbalanced tires. So you should start there first.

That's a good idea. It could be a band separating and hard to see so keep that in mind.
