What size tires do you have? Post the size up and someone can use a tire calculator to see what the difference in speed would be over stock. Wheel size doesn't make a difference, its the outer diameter of the tires.

i live by this because almost all the agencies i know will not write speeding tickets for anything under 10mph over the posted limit...anyways back to the OP i dont think that your 20" wheels caused this unless you have some extremely tall sidewall tires on them or have had gears installed recently with out recalibrating your computer.....

Nope, its the revs per mile of the tires.
Its not the diameter of ther rim that determines
revs per mile of the tire installed on it.
Wrap a tape measurer around your OEM 17"
tire/rim and then wrap it around the 20"
tire/rim to see the difference.

if you had a garmin gps, it wouldn't matter what size your wheels are, they give the most accurate speed read outs
