If you are one of the 85% of the population who don’t regularly check tyre pressure, you need nitrogen. 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.
Because of their large size, nitrogen molecules are the least permeable and stay in your tyre longer. It’s not about the nitrogen. It’s about reducing oxygen, water vapor and other gases. By reducing the percentage of oxygen, water vapor and other gases in your tyres from 22% to 7% or lower, your tyres will maintain proper pressure longer than if you use “plain old air.” For example, with 95% nitrogen in your tyres, they retain optimal pressure three to four times longer.
Proper tyre pressure is a big deal. Maintain it with nitrogen, and you’ll see these three primary benefits:
- Increased Fuel Efficiency – Correct tyre pressure keeps the manufacturer’s recommended “contact patch” on the road. This lessens the rolling resistance and maximizes fuel efficiency.
- Longer Tyre 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 tyre liners and belt packages; nitrogen does not.
- Increased Safety – Under-inflated tyres cause 90% of blowouts. Nitrogen provides more reliable pressure for reduced blowout potential. Longer Rim Life – Rim rust caused by condensation from water vapor and other gases can get caught in valves and create slow leaks in tyres. Nitrogen is completely dry, so it eliminates the potential for condensation.
