So the float which most people think would give them some kind of lifting power and slight advantage would not happen, because the air would be heavily compressed in your tire... He when compressed to the correct PSI to hold a riders weight would also probably end up weighing more than the air originally intended for the tires. <-- i could be wrong on this last part

Now you could fill your tire with pure nitrogen that may give you little + on your ride but prob not... Since Air is about 78% nitrogen, 21% oxygen, and 1%. Oxygen is actually bad for your tire. It'll eat up the rubber over time, oxidation. It’s also the biggest culprit of lost air pressure. Oxygen is normally the first major air component in your tire to escape over time.

Ya' think?
