It is not the rim size that needs to be recalibrated, its the overall height of the tire that makes the difference. I just had to let me dealer know how many revolutions per mile the tire makes and they change it in their computer. If the height of the 17's and the 20's with tires is the same then you dont have the change anything. Welcome to Dodgetalk!!!

You can compare the two different tires you have using this to find out how much they are actually off.

You have to go in to miscellaneous with the drb3 and select pinion factor, then scroll down to the size of the tires you have on it, and that is it!
