Why don't the tires inflate for a long time?
Please check regularly for all tire pressure during cooling (at least once a month), including the spare tire. The correct inflation rate of the tire under cooling conditions shall be based on the parameters recommended by the vehicle manufacturer. If barometric pressure decreases too quickly, please check the cause.The definition of tyre cooling: at least three hours after parking, or no more than 2 km of tire travel. If you can only measure the tire pressure during the hot tire, please subtract the measured tire pressure value by about 0.3 bar (=4psi), that is, the tire cooling and charging pressure.Any low pressure tire can cause excessive heat and may eventually cause a sudden tire crash. In addition, no matter the tire inflation pressure is too high or too low, the tire tread will be partially worn out, so as to shorten the service life of the tire
In addition, check the tire pressure with a high quality barometer. Don't take too much notice of your eyes. You can't judge the tire inflation pressure from the appearance. Ensure accuracy of tire pressure gauges and measuring techniques.
It is recommended that you check your tire pressure at least once a month or before each long journey, including spare tyres. Examination of tire pressure should be carried out under cold tire condition.
The tyre is well sealed and airtight.Every time you go to the maintenance, the maintenance personnel have been inflated for you.Probably for pneumatic hollow tires
