The standard air pressure of the tire is marked on the driver's door or on the door (this standard value can also be found on the fuel tank cap and on the instruction manual). It should be noted that the air pressure has different representation standard units, generally there are 3 to 4 types. Just like the weight of useful kilograms is also useful, there are also 3 to 4 kinds of marking units on the barometer, such as kg/cm2, bar, PSI and kpa. The conversion relationship between them is as follows: 1bar=1.02kg /cm2=102kpa=14.5PSI. Baiye Auto Parts Network recommends that the owner should not calculate how to calculate the position of the pointer on the barometer. What position is used to indicate this position? Then, look at the standard value of the corresponding air pressure unit of the vehicle. Look at the difference between the measured value and the standard value. If it is too high, let go of some gas. If it is low, it should be filled with air until the tire pressure matches the standard pressure.
Note that if the vehicle is found to require qi, there is an inflator that can be solved on its own. If there is no owner, it needs to be inflated at the nearest tire store. It is best not to choose a distance to the inflation point of more than 1.6km. Because the car is within 1.6Km after standing for 4 hours, the air pressure of the tire is still accurate. If it exceeds 1.6Km, it should be charged 5% when inflating.
According to relevant information, the standard air pressure of ordinary car tires is preferably: 2.5kg for the front wheel and 2.7kg for the rear wheel; 2.3kg for the front wheel and 2.5kg for the rear wheel. This ensures safe driving and comfort while minimizing fuel consumption.
