It is a good habit to check the tires first before driving, but during the check, some car owners will find that the tires appear to be flat when the tire pressure is normal. Even these tires can not avoid such a phenomenon; Why does this happen? Should I pump the tires up again ?Most car owners have this question.

  In the currentmarket,most of the industrial and agricultural and ATV tires are used in the vacuum tire, it is also a tubeless pneumatic tire. Such tire in the inside and outside is a layer of "air", so that the tires look a little flat, but in fact the tire pressure is normal phenomenon;This phenomenon never affect the use of industrial and agricultural tires and ATV, because the tires will adjust according to their own pressure.

  When the tire pressure is too high or too low, timely adjustment is needed. If the tire looks flat and the pressure is normal, there is no need to worry too much, because it is only a superficial phenomenon.
