Smaller diameter wheels = lower gearing = lower mileage... right?

Smaller diameter wheels are generally lighter, that can help with economy, but otherwise, WHEEL diameter does not matter. Smaller diameter TIRES will have the same effect as a shorter gear ratio, quicker acceleration, higher revs, lower economy. For better economy, you'd want TALLER tires to lower the engine RPM at highway speeds. |
