New tires, strange noise

I just got Pilot sport A/S 3+ on rear wheels. They didn't have the front ones so they ordered them and I'll go back tomorrow to replace my front tires as well. Meanwhile, after driving away I got this strange high frequency noise from the back at about 55 mph.


By the time I drove off the shop was closed so I have to take it back tomorrow. Any idea what it is? Only happens at about 50-60mph, no physical vibration.

Dafaq is wrong with this car at 50mph/80kph? Initially thought you are the next diff victim but that's a new funky sound. If everything lead up to 88mph and car made fire tracks where ever it went, I wouldn't care about all the noises it made.

Just so we're clear, are you referring to the chirping noise in the last 1sec of the video?

yep.

I drove it again this morning and heard the noise at about 55 mph. This time I paid more attention and realized it was coming from the top. Opened and closed the sunroof and noise completely went away. Must have been a leaf or something stuck in the sunroof.
