    New P85D. Got it less than two months ago. Last week, had SC put 21s to replace the 19s I got the car with. Shortly after, I started to notice a squeal as the car comes to a stop after applying the brakes at very low speeds. Don't believe I heard that noise before getting the 21s. Normal? Could the installation of the 21s be causing this? Any thoughts welcome. Thanks.

    I'm sorry. Poor attempt at humor. You wrote "breaks" instead of "brakes."

    That said, I wouldn't think changing the wheel size should have any effect on brake squeal. If the pads and rotors were new and not properly bedded in you could develop squeal, but they wouldn't have been replaced during a wheel change.

    This is most likely (99.99% certain) not at all related to the wheel change, since the braking hardware is not a part of the wheel at all. Some Teslas just do this. My P85 does as well. I think the service center can fix.

    Brakes that are used lightly tend to develop a glaze that can create squeaks. Go out and hit the brakes real hard two or three times from 60 mph and see if that doesn't cure it.

    Excuse the necrobump, but having the same issue. Did you find a solution, or can anyone relate to this?

    probably because the brakes dont get used often. you can try to bring it up to speed and then applying the brakes heavily but not stomp on it as that could lead to warped rotors.

    Forgot to mention I tried this with the 21s on to no avail. As soon as I mounted my 19s for the winter, the noise went away.
