Adjusting reported mileage (as in distance traveled, not mpg) is how you adjust tire size in the UG. If the UG is already calibrated for mileage, then you can calculate the difference in revs per mile of your previous (calibrated) tire size and your new tire size, then adjust the UG accordingly.

Or you can use real numbers to calibrate at your next fill- or do both if you're feeling ambitious, do the math and then verify by calibrating at the pump.
