Often customers bring vehicles to check periodically, the car has been used for quite a long time, the distance is quite far and the car is often short of nitrogen.
The composition of air includes: 1% steam and other gases - leakage rate 250 times faster than nitrogen gas, 21% oxygen gas - leakage rate 3 to 4 times faster than nitrogen gas, 78% of nitrogen - the largest molecule in air, dry, non-flammable.
Due to its large molecular size, nitrogen has the lowest risk of air leakage and can survive longer inside tires.
The problem is not nitrogen gas, but it is important to reduce oxygen, steam and other gases.
With the reduction of oxygen, steam and other gases from 22% to 7% or even lower, your tires will maintain proper pressure longer than when you merely use gas. often. For example, if your tire contains 95% nitrogen gas, they can keep the optimal pressure longer than 3-4 times.
Proper tire pressure is an extremely important issue.
When maintaining tire pressure with nitrogen, you can immediately feel its outstanding superiority:
- Fuel economy: Standard tire pressure according to manufacturer's 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, although the vehicle is more traceable but the fuel consumption will increase significantly, while the tire pressure is higher than the standard value, tire more slippage on the road surface, this is also the reason the car consumes more fuel.
- Increasing the life of tires and wheels: When exposed to other substances, oxygen causes oxidation reactions. Oxidation causes rubber to become more brittle resulting in loss of elasticity. In addition, at high temperatures and pressures, oxygen gas reacts and harms the entire lining and inner lining of tires. At the position of the valve seat, condensation of water vapor and other gases will cause rust and create small holes inside the tire. But these things will absolutely not happen when you use nitrogen gas.
- High safety: Low tire pressure (small tire) is responsible for 90% of tire explosion. Nitrogen gas provides reasonable pressure to reduce the risk of potential tire explosion. When pumping tires with gas normally, every 4 - 5 weeks, the warning signal of your tire pressure is blinking continuously. But after pumping the tires with nitrogen, the indicator light system didn't have to turn on for 53 weeks! With the tire down slightly longer, you will reduce the time it takes to check and pump the tires periodically.
Bridgestone / Firestone researchers said that nitrogen gas from 93-95% is the best for your tires.
According to Ford Motor Co., there is no difference between pure nitrogen to 96% or 99%.
