People say that big truck tires are best filled with nitrogen. Why is that?
Because lorries are the most frequent vehicle accidents. The freight car has a large load, a long running time, and a long period of high temperature. Therefore, it is very easy to produce a flat tire, which is more likely to lead to serious traffic accidents
But the high temperature causes the tire rubber aging, the fatigue strength drops, the tread wear is fierce, is also the important factor which possibly the tire burst. Compared with the general high pressure air, high purity nitrogen for anaerobic and almost free of moisture without oil, its low thermal expansion coefficient, low thermal conductivity, slow heating, reducing the tire heat accumulation rate, non combustible nor combustion characteristics, so it can greatly reduce the chance of puncture.
According to statistics, China's highway traffic accidents due to tire causes accounted for more than 45%, which due to tire burst causing the vehicle midway through the "anchor" accounted for 84.8%, tire often caused the tragedy of the elderly. When driving, the tire temperature due to friction with the ground increased, especially in the high-speed driving and emergency braking, the air in the tyre temperature will rise rapidly due to thermal expansion and contraction, tire pressure surge, so there will be a possibility.
