A detail to pay attention to when inflating car tires, otherwise the loss outweighs the gain

Details determine everything. Although this sentence may not apply to all aspects, sometimes, if you don't pay attention, you will easily suffer.

For example, when we inflate a tire, after it is inflated to the specified value, we need to remove the air pipe and measure it again, which is the most accurate. And one person needs to use a barometer to measure, because there are errors between the barometers, and everyone's measurement also has errors.

Usually, there is a plastic cap on each tire valve. The main function of this cap is to prevent dust and pebbles from entering the valve. The next time it is inflated, it is easy to form a blockage at the valve needle and cause air leakage. Covering a cap can also prevent the valve needle from rusting, copper rust, and keep the valve clean.
