Note: Regarding Tire Size
Adjust only if speedometer is off due to the increase
or decrease in tire size. The factory GM PCM can only
calculate up to a certain tire size before it will disable
the traction control system ( i.e. ABS brake system). It will
correct the speedometer but if tire size is over PCM limit, it
will trigger a check engine light or an ABS light. The Max
Tire size limit is a 35 inch tire.
