Hydrogen is not hygroscopic...does not contain absorb water as air and pressure will remain more consistent.
However, Nitrogen also runs cooler. It will not expand or increase its pressure as air does in a racing slick; therefore, a drag slick will not grow with Nitrogen.
This is one of the many reasons why NASCAR, airplanes and military vehicles run Nitrogen in their tires. With NASCAR race cars, the tires growth is consistent and does not change the the suspension settings.
