Well, to get a true picture of things, you have to know the revolutions per mile of each fitment, which is based on the tires mounted on each wheel. Then you calculate the delta, or difference, between the two. If the percentage of difference is significant, say more than 3 or 4 percent, then it may be enough to mess up the calculations of the various processors. It's vehicle dependent. You only provided the wheel diameters, which are 4.5% different, but you need to factor with the tires. I believe only a Chevy dealer, or a shop with the appropriate computer programming, can reprogram for a different revolutions per mile.
