Looking for some help changing tire size on a 2018 Ford F-150. I have an older Professional MPVI box(Probably 17 years old with a ton of credits) using the 3.7.1896 beta software, When I start the scanner, scans normally but when you open up the controls panel it is blank. I have hunted all around and can't seem to find where to input the new tire size. Thanks for the support.
Phil
