Actually he switched to the smaller tires, which means that he is counting more distance on his odometer not less. The smaller tires spin faster and they turn more times per mile, so therefore in the same distance as the larger tires they will cause the odometer to count more miles.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
