A larger wheel has a larger circumference. Imagine a hypothetical wheel with a circumference of 100 inches, and another with a circumference of 200 inches. Both of these wheels are connected to an odometer that reads "1 turn = 100 inches". One complete turn of the bigger wheel would take you 200 inches though, or, to go 100 inches, you would only need half a turn. This half of a turn would only show as 50 inches on the odometer, thus the bigger wheel would make the odometer read low.
