So I have been having a debate with a friend at work about how tire size would affect mileage/speedometer readings. It is my assertion that if you went from smaller to larger tires (with a larger outside circumference) you would get a speedometer reading that is lower than actual groundspeed, as the speedometer is based on the rotation of the axle, not the groundspeed...and that your mileage would actually decrease because it takes more power to push the vehicle on those tires as they have a greater surface area and would create more resistance/friction.
Am I right, or am I talking more out of my ass than usual?
