Compact digital pressure gauge from China

After once again I decided to check the tire pressure using a pump with a built-in pressure gauge, I decided to buy a compact digital pressure gauge from China. This device will be useful to all motorists. The most important thing is that it is unnecessary to remove the pump from the trunk with each measurement, unwind the hose and then do all these manipulations in the reverse order. And if it's winter and a good minus?

When to pressurize your tires :

- if you have tires with a low profile (less risk of earning a hernia on the wheel);

- if you want the car to go a little "faster";

-if you have soft rubber (at low pressure it will wear out faster).

Cons: unevenness of the road is felt more strongly, more load on the suspension, longer braking distance.

When to relieve pressure :

- if you want the car to go "softer";

- so that the car is less responsive to road pits and, accordingly, does not load the suspension.

Cons: Lower tire pressure increases fuel consumption and reduces maneuverability, rubber wears out faster and there is a risk of side cuts on the tires.

And another very important point. The best time to check the tire pressure is in the morning. The tires and the car must still be cold so that the tires and air temperature are the same.

And so let's start:

The device itself from China is simpler than a hammer. ;)

One button, it's ON. and it is also OFF.
Long press - ON or OFF. Short presses - select the pressure display mode, or rather its units - Psi, Bar, kPa, Kg / cm2.
There is an auto shutdown function.
