With the approach of summer, explosion-proof tires have become the biggest concern of car owners. According to statistics, 1/3 of traffic accidents on expressways are caused by tires, and the largest proportion of them is puncture. There are a lot of methods on the Internet about running flat tires for summer cars, but are they really useful?
It is said on the Internet that nitrogen filling of tires can prevent tire blowouts. Is this really the case?
Nitrogen is an inert gas, the free path of molecules is larger than that of oxygen, and the permeability in rubber is low. Therefore, the tire pressure drop rate is greatly reduced, and the time to maintain the normal tire pressure increases. At the same time, the volumetric expansion of nitrogen gas is much lower than that of air containing moisture when the temperature changes, thus reducing the chance of puncture. However, someone did an experiment in which nitrogen and air were respectively filled on the left and right tires of the same car. Then, record the tire pressure and temperature every 10km. The advantage of nitrogen is not obvious in practical applications.
Lowering tire pressure is also a method that people often use. Everyone knows the principle of thermal expansion and contraction. If the air pressure in the tire is too high, the tire will easily burst when heated. Therefore, in summer, car owners will lower the tire pressure, but is this really good?
There are many steel wires inside the tire to hold the entire tire. Driving under the condition of insufficient tire pressure, due to the irregular deformation of the tire, the steel wire inside the tire is constantly deformed, which causes the temperature of the steel wire to rise sharply, and it is easy to break. Moreover, when the tire temperature rises during driving, the possibility of a tire blowout will increase. Raising 0.1 or 0.2 BAR on the premise of normal tire pressure can reduce the deformation and fracture of the steel wire, thereby reducing the probability of a tire blowout.
