16 vs 17 inch tires does not change the overall tire diameter. Only changes the size of the sidewall, therefore, no affect on speedometer readings.
That being said...if he changed out the tires and DID change the diameter by installing completely different type tires - the speedometer calibrated to show fast would still not be reduced to show less speed than actual.
