Should You Really Put Nitrogen in Your Car Tires?

The composition of the air includes: 1% water vapor and other gases – leakage rate 250 times faster than nitrogen gas 21% oxygen – speed The composition of air includes:

1% water vapor and other gases – leakage rate 250 times faster than nitrogen gas 21% oxygen – leak rate 3 to 4 times faster than nitrogen gas 78% nitrogen gas – the largest molecule in air, dry, not flammable.

Because of its large molecular size, Nitrogen has the lowest risk of exhaust and can last longer inside the tires.

The problem is not nitrogen, but the reduction of oxygen, water vapor, and other gases.

By reducing oxygen, steam and other gases from 22% to 7% or even less, your tires will maintain the proper pressure for longer than when you merely use gas. often. For example, if your tires contain 95% nitrogen, they can hold the optimal pressure for 3-4 times longer.


Proper tire pressure is of utmost importance.

When maintaining tire pressure with nitrogen gas, you can immediately feel its outstanding superiority:

– Fuel economy: Standard tire pressure following the manufacturers’ recommendations will help the car operate more stably. If the tire pressure is less than the standard value, the friction between the tire and the road surface will increase, but the vehicle will stick more but the fuel consumption will increase significantly, while when the tire pressure is higher than the standard value, the tire will slip more on the road, which is also the reason why the car is more fuel-efficient.

– Increasing the life of tires and wheels: When exposed to other substances, oxygen causes oxidation reactions. Oxidation makes the rubber more brittle which leads to loss of elasticity. In addition, at high temperatures and pressures, oxygen reacts and damages the entire lining and inner lining of the tire. At the foot of the valve, condensation of steam and other gases will cause rust and create small holes inside the tire. None of this happens when you use nitrogen.

– High safety: Low tire pressure (low tire pressure) is a cause of 90% of tires explosion. Nitrogen provides reasonable pressure to reduce the risk of tires explosion. When pumping tires with normal air, every 4 to 5 weeks, the warning signal of your tire pressure at low level blinks continuously. But after pumping tires with nitrogen, the indicator didn’t have to turn on for 53 weeks! With the tire getting longer, you will reduce the time you need to check and pump tires regularly.

Bridgestone / Firestone researchers say nitrogen at a ratio of 93-95% is best for your tires.

According to Ford Motor Co., there is no difference between pure nitrogen to 96% or 99%.
