8 Tips for Using the Tire Pressure Gauge Correctly


Correct tire calibration ensures tire life, driver safety and fuel economy. However, to do the right job in your auto repair shop, auto shop or auto center , you need to know How To Use Tire Pressure Gauge the right way. So to help you, we have prepared this post.

Here we will give you some tips so that you can put into practice while ensuring your customer quality service. Interested in learning everything from us? So, follow our article very carefully!

1. Understand how the tire gauge works
Before calibrating a car's tires, you really need to understand how the tire gauge works . You from the automotive industry should already know that there are some supposed differences in reading and pressure in the digital calibrator. Already in common calibrators, the hose does not get pressure and this happens for the sake of safety.

In these calibrators, there is only one diaphragm inside the device, which opens and closes, allowing or not the air passage. However, when in disuse, the pressure is equivalent to external pressure, ie zero.

2. Fit hose nozzle to tire valve
When you put the hose nozzle into the tire valve, the internal air exits into the hose, which gets pressurized. In the device, you can read this pressure and compare the pressure obtained (in the hose) with the one programmed, so that you can use the tire gauge correctly.

3. Verify that the player is set to 110 PSI
Our third tip is to check if the device is set to 110 PSI. If it is set and you find that the pressure in the hose is lower, you should open the diaphragm.

This will allow air to pass through the line coming from the compressor into the tire. But if the pressure in the hose is higher, the diaphragm will not open and the device will release air from the hose into the environment and lower the pressure in the tire.


4. Reach the preset pressure
For tires with low pressure, the calibrator will equalize. It will reach the programmed pressure. The device will also beep. At this point you will have the same pressure on the gauge, hose and tire. And this is explained by physics, it is a principle called the communicating vessel.

5. Remove the tire valve nozzle
You must remove the nozzle from the tire valve. By doing so, the air in the hose will be expelled and the pressure will return to zero. Inside the calibrator, the diaphragm will close and prevent air from coming out of the compressor.

6. Put the hose in the valve
In the sixth tip on how to use the tire gauge properly, you should put the hose in the valve. This will increase the volume (tire + hose) and then you will get a lower reading because the amount of air in the tire is the same.

However, you will have to distribute the air over this higher volume. Remember that the longer the hose length, the greater the difference.

7. Check pressure with a short hose calibrator
If you have any questions, you should measure the pressure with a short hose calibrator. But stay tuned! If you use this short hose calibrator as soon as you calibrate with the long hose calibrator, you will see no difference. To calibrate the tires, it will not matter the hose length. However, if you need to measure, measure and verify that it is correct, you should use the short hose.

Also remember that when you put the digital calibrator hose in the valve, the air does not flow from the calibrator to the tire but from the tire to the calibrator. Therefore, this is why digital calibrators have a button labeled “Empty” that, when pressed, opens the diaphragm allowing air to vent to the compressor. However, if the tire is flat, there will be no air to inflate the hose and the pressure comparison process will not begin, ie everything will be as it is.

8. Pay attention to pounds
And to finish our tips on how to use the tire gauge, you should pay attention to the pounds. When calibrating tires, never add extra pounds because of the hose. Guide your customers to keep their car tires always calibrated. This will help to save tires and fuel, and will also ensure the safety of the driver and occupants of the car.

See how easy it is to use the tire gauge? Now that you know, you can run the calibration service faster and better, right? In addition, it will also assist your customer when he has to calibrate the car tires.
