2004 Mazda 3- Excessive Noise at High Speeds

[tk91]

Hello all, I was hoping someone can provide me with an insight on what this noise is?

I just started to notice this noise and I assumed it was due to the mechanic at my oil change who adjusted the tire pressures. I checked the pressure and it was about 37psi… I don’t think this noise is due to the tire pressure…

I don’t think it’s an engine noise because the noise gets louder with speed and not with RPM.

It sounds like a humming rhythm, it gets very clear on the video at 0:16 – 0:22, 0:44 – 0:51, and 1:07 – 1:14

Thanks you all for your comments.

sounds like a bad wheel bearing

First thought would be a wheel bearing, but that's pretty damn loud. It sounds like something is rubbing, are you lowered? Also 37psi is a bit high for your tires, 32-34 is better.

Sounds like your tires have uneven wear and that's why it sounds like that...

i fixed mine by buying camber kits set te camber to 0 and bought new tires with no issues anymore

It is kind of reminiscent of farked up tires due to camber wear, but still sounds very loud. Unless the tires were rotated and the farked up tire(s) are now on the front, that could explain the sudden excessive noise, you never know.
