Experimenting with tire pressure sounds interesting, and would be a lot easier than comparing different sizes and brands of tires.

But I'm skeptical of anyone's ability to "feel" the probably minor differences that would result from five or ten psi upward or downward.

I think the most practical way of detecting a difference would be to use a road with a consistent, slight downward slope. Coast down it repeatedly with different air pressure and note speeds. Try for days with no wind and consistent temperatures if possible.

 10 PSI would be a striking difference if he's running the 32s at ~60 PSI. If he was riding the 25s at 100 psi, not so much.
