I am sure this has been addressed in the forum, but I could not find the thread. I currently have the OEM Pirelli 275/50/22 inch tires. I am putting on a set of Nitto Nomad Grapplers for fall/winter in MN. The 22 in Pirelli's have 614 revolutions per mile and the 275/60/20 Nitto's have 611 revolutions per mile for a 0.50% difference. Seems pretty close to me, but someone at the SC said I should bring it in to update the speedometer/odometer.

They said the software needs to change for braking and some other reasons. Is that correct? Do I need to bring it in or can I just swap the tires and move on, knowing that the speedometer and odometer will remain very close to accurate?

Odometer/computer and cameras all should be recalibrated to do it "right."
