The trouble of an inflated tire without a pneumatic tire
There is a tremendous progress in the development of pneumatic tire on the tire in history, to bring comfort at the same time, also brought inflation, tire, tire and other new troubles.Pneumatic tire is closed with rubber pressure air, the air is compressed, air molecules produce repulsive force generated elastic characteristics of inflatable cushion performance and low rolling resistance tires superior so far no other tire can go beyond. Air molecules are very small and run out of cracks in rubber molecules, so pneumatic tires often need air. Pneumatic tire is easy to nail, glass and other sharp objects punctured, sometimes need to tire, tire is very troublesome. If it is a lightweight bicycle tires, push the tire easily, if the electric bicycle, motorcycle tires heavy flat push tyre, it pushed up, walk 1 kilometers, I am afraid to be tired out. If the car tires were then can't do anything.
High speed tyres are extremely dangerous and often cause serious traffic accidents. According to statistics, 70% of the highway traffic accidents in our country are related to tires. The automobile tire burst has become a "super killer" on the freeway". As the vehicle speed on the highway, the surface temperature and the pressure in the tire increased continuous friction, for the "health" of the tire, the rising of the temperature and pressure can be overcome, but for excessive wear or significant trauma, scratches on the tires, it is difficult to bear huge tire pressure, therefore a higher probability of "accident".
According to the statistics of the traffic department, serious traffic accidents caused by automobile tire leakage and tyre burst account for 46.8% of the total accidents. On the highway, this ratio is as high as 60%-70%, which is the highest proportion of all kinds of accidents. According to the test, the car at 160 kilometers per hour or more driving when a flat tire accident, the driver's death rate was 100%. Flat tire has become the three biggest killer of China's road traffic with tired driving and speeding.
