If you want to do it yourself you need Forscan, and know the setting to change for tire size. Unfortunately, I'm not 100% which line it is, so I can't help you there.

While I have done plenty of Forscan updates to my F150, I haven't attempted any on the Mustang yet. Therefore, I can only pass this along while saying I have not personally confirmed these with my vehicle:

Module: ABS
Address: 760-02-01
Second segment, fourth digit

Here's a link to the post with the spreadsheet:

IceAge, was this on your Dark Horse or GT? What tires and size did you change from/to? I'm guessing maybe PS4's?
