Tires need to be inflated once a month, the maintenance master said that the leak can not be detected, there is a good way to deal with no, it is too annoying to inflate every month.
The normal tire pressure loss is about 0.07bar/ months, so it is necessary to measure the tire pressure at least once a month. For safety, you should check it before you suggest long distance high speed. (monthly check, not inflated every month)
Tires are pierced, bad repair, valve rubber aging, check the air pressure, the valve core is not reset, all of the above circumstances will lead to chronic tire leakage. When checking, it is recommended to inflate to the maximum tire pressure of about 3.0bar, and then the tires are immersed in the tank for full inspection. (it's a hard job.)
The tire pressure of a car is usually 2.2, with a full load of 2.4 (usually the rear wheel). The normal tire pressure is also the first time for tyres to be used longer, so stick to the trouble.
