Thanks for pointing out the above link. It is really good. One thing, i put in the numbers and the smaller wheel is saying the mileage will be less, not more. Going down to a 16 from 18, it says speedometer will read 60, but actual speed is 61.4.

It's the overall tire diameter/circumference that changes your overall gearing, not your wheel size... Are you altering the tire sizes in the calculator?
Yes, i entered in the tire #s, and the wheel #s. the 16 inch wheel and tire are 47 mm larger in circumference. After reading the other post, i guess when he says wheel, he meant wheel and tire. my math came out to be the mileage listed will be 117 miles less than actual. This isnt a big deal, and even the speed is only off by 1.5 mph. my total miles being under reported is fine by me.
my bad, i figured it would be apparent that overall spinning circumference was what we were dealing with, which figures both the tires and the rims. Clearly rim size isn't as big of a deal if it's offset by a rediculously tall profile tire on a small rim.
