Nitrogen is a dry, inert gas used to inflate tires for improved performance, more tire longevity and better fuel economy. Precision Auto offers nitrogen. So whether your vehicle came with nitrogen in the tires from the factory or you would like to switch to nitrogen, we can help. Less tire pressure fluctuation-While both nitrogen and oxygen can permeate rubber, nitrogen does it much more slowly. It might take 6 months to lose 2 psi with nitrogen, compared to just a month with air. NASCAR uses nitrogen instead of air in their tires because nitrogen has a much more consistent rate of expansion and contraction.
