and I understand dealer can reset your speedo/odometer to new wheel size.
Don't know about the F350....but starting in 2015, with an F150 it is not possible to have the dealer recalibrate the speedo/odo to compensate for tire size changes. For some reason, in their infinite wisdom Ford decided to take away that ability in the software for the trucks. You can read all about it on the F150 forums (I've also got a 2016 F150) where guys have installed larger tires and then found the dealer couldn't correct the speedometer. Lots of threads on the subject.
It can be done - but involves buying an expensive aftermarket tuner.
