Recently, the weather is heating up, took a look at the tire pressure, the good guy is nearly 2.9, just a week to pick up the car, the factory tire pressure must be high. The tire pressure in the cold car state is 2.6, and the app indicates that the normal tire pressure is 2.5. Considering that the weather is getting hotter and hotter, and we have to run at high speed every day, we want to give the tires some air.
Accidentally see online that the air pump can be deflated, so took out the tool with the car pump, read the instructions, used to inflate, deflate is really very convenient, and there is a barometer, can monitor tire pressure in real time.
Screw the nozzle of the air pump to the tire valve core, and there is a button next to it. Press it to release the air.
Let off 0.1 gas, cool the car 2.5, finish the high speed 2.7. The advantage of deflating with an air pump is that the tire pressure can be seen in real time to ensure the consistency of the tire pressure.
