Yes. But the overhead may still be off ( not accurate ) if it is off currently.

If you have a Smarty you can reprogram the tire height yourself. But I doubt it will correct the overhead

If Smarty modifies the tire size, the computer will use the new values for it's fuel mileage calculation...

jmlcolorado has a 2003 model truck....the dealer can go in and modify the tire revolutions per mile thru the pinion factor / abs section.
