The circumference of the tire does not change (mounted on rim and under vehicle weight vs mounted on rim but not on vehicle) therefore the revolutions per mile also does not change.
This being the case why do I read over and over again I should base my new gear ratio on the height (diameter) of the tire under the weight of the vehicle?
