Does my Langdong whole car 2 2 air pressure hurt the tires

Generally, no, choose according to the manual, and generally about it. It can't be high or low.

Air pressure is the lifeline of a tire, and too much and too low will shorten the life of the tire. If the air pressure is too low, the deformation of the carcass will increase, the sidewall is prone to cracks, and at the same time, it will produce flexural motion, resulting in excessive heating, promoting rubber aging, cord layer fatigue, cord breakage, and will also increase the tire grounding area and accelerate shoulder wear. If the air pressure is too high, the tire cord will be subjected to excessive stretch deformation, the elasticity of the carcass will decrease, and the load on the car will increase during driving, and the impact will produce internal cracks and bursts, and at the same time, the high air pressure will also accelerate the wear of the tire crown, and reduce the rolling resistance.

Yes, just keep the four tires at normal pressure, and the tire pressure between the two front and rear wheels should be the same.

It's okay if the tire pressure doesn't exceed the standard, but keep in mind that the tire pressure between the two front wheels and the two rear wheels should be the same.

This situation is usually very slow air leakage, for a while can not find out which tire is it, at this time you can use the tire pressure gauge to measure, front, rear, if there is a lack of air, make up, and then observe the tire pressure warning light, if a few days later and on, it may be necessary to pick up the tire to check. 4S shop, the usual way for maintenance personnel to deal with it is to adjust the pressure of the two front tires and adjust the pressure of the rear tires, and then cut off the tire pressure alarm, and let us run for another day to see, if you don't call the police again, it will be no problem, and then call the police may be that the tire is punctured, and you need to go to the 4S shop to check.

The tire pressure monitoring light is on, and sometimes the tire pressure is too high.

Generally, the international GBT 2978-2008 standard stipulates that the inflation pressure of car tires meets the requirements of Table 1-Table 15

Standard tires:; Reinforced tires:; Maximum air pressure: should not be greater than. Therefore, when a tire exceeds it, it will also trigger the tire pressure monitoring light to turn on.

The tire pressure monitoring light is on due to low tire pressure driving time for too long.

This situation usually occurs when the tire pressure of a tire is too low, and the tire temperature rises due to high-speed operation, which causes the tire pressure to rise, and then the tire pressure rises, so you should stop and rest in time or replace the spare tire.

The tire pressure monitoring light is on due to the low tire pressure that has not been refueled for a long time.

When the air pressure is lower than the bottom, the tire pressure monitoring light is on, so you should usually do a check to see if the tire pressure detector is normal. When the car is in trouble, if the tire pressure monitor does not alarm in time, it is a problem with the tire pressure monitor; If the ignition switch is on start, the indicator light point and the TPMS indicator light will be on at the same time for 2s and then turn off. In this case, either the original receiver of the vehicle has not been learned, or the receiver controller has been replaced, and the receiver controller has not been learned.

You can go to the 4S store and ask professionals to use handheld learning tools to re-obtain all tire sensor IDs and bind the receiving controllers.

Yes, you can check the air pressure, if it's not enough, it's fine.

This is completely okay and does not affect it;

When you open the door, it is displayed on the pillar.
