Why Nitrogen?

If you are one of the 85% of Americans who don’t regularly check tire pressure, you need nitrogen.

Due to it’s larger molecule size, nitrogen is less permeable than oxygen and thus remains in your tire longer.

The air we breathe,
the air that’s in your tires.

can lose 1.5 psi a month


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 contaminants in your tires, they tires will maintain proper pressure longer than with compressed air.

Oxygen reacts and damages inner liners and belts; nitrogen does not Small bits of corrosion from wheels can prevent valves from seating properly, leading to air loss.

Proper tire pressure is a big deal. Maintain it with nitrogen and you’ll see many benefits.

Increased Fuel Efficiency
Longer Tire Life
Increased Safety
Improved TPMS Performance
Longer Rim Life

Why not eliminate all oxygen and water vapor? What purity of nitrogen do I need?

Research by tire manufacturers has shown that nitrogen purity beyond a certain point does not provide additional benefits. In fact, you can get all the benefits of nitrogen with a purity between 93% and 98%.
