    2019 f150 tire size help

    2019 f150 Ecoboost. Can't change tire size.
    Speedo\tire size has no effect ...
    I was told by tech help support to adjust through scanner/vehicle/controls and special functions....it's blank....
    Any other suggestions? Tia

    Looks like its coming from the bcm. Unless you change it from the source.

    I've read that you can use forscan to do tire size changes.
