We take in nitrogen with every breath. Air is composed of:
1% Water Vapor and Other Gases – Escapes up to 250 times faster than Nitrogen
21% Oxygen – Escapes 3-4 times faster than Nitrogen
78% Nitrogen – The largest molecule in air, dry, non-flammable.
Increased Fuel Efficiency – Correct tire pressure keeps the manufacturer's recommended “contact patch” on the road. This lessens the rolling resistance and maximizes fuel efficiency
Longer Tire Life – When it comes in contact with other materials, oxygen causes oxidation. Oxidation can make rubber brittle and cause it to lose tensile strength. In addition, at high temperatures and pressures, oxygen reacts and damages inner tire liners and belt packages; nitrogen does not.
Increased Safety – Under-inflated tires cause 90% of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential.
