How to Use a Digital Tire Pressure Gauge

Accutire MS 4021B digital tire pressure gauge

Getting the right tire pressure is something simple and very important in as far as overall tire performance of your car is concerned. When your tires are inflated properly, they provide you a longer life cycle, allow you proper steering control, better response on the road, improved fuel efficiency, and more importantly a smooth ride.

Inappropriate inflation of your tires is bound to give you challenges on the road, including premature wear and tear of your treads, and tire failure. The only way to deal with this accordingly is to check the tires on a regular basis.

With a pressure gauge, you have a better shot at ensuring your tires will perform at their peak. Without it, you cannot easily get the right tire pressure, neither can you know the right pressure for your car. There are different types of pressure gauges in the market, offering you convenient usage.

How to Use a Digital Tire Pressure Gauge

Checking the tire pressure

There are some important steps that you should follow when you want to read the tire pressure accordingly:

  • Read the information label

The information label on the tires will give you the right pressure for your tires. It is indicated on the door frame on the driver’s side, or the door ledge. In some cars, this information is available either in the owner’s manual or the glove box.

  • Note the cold inflation pressure

Before you drive, at least 3 – 4 hours, make sure you inspect the tires. The appropriate pressure is the cold inflation pressure. Remember that when you are driving, the tires will certainly heat up, and as a result this increases the pressure.

  • Check all tires

Having checked the cold inflation pressure ahead of time, make sure you check the pressure on all the tires, including the spare tire if you drive around with one. It is recommended that you check the pressure at least on a monthly basis.

Over time, tires will tend to lose pressure in the course of usage. Other than that, the fluctuation in outdoor temperature will also affect the pressure, hence the need for you to constantly look into the tires.

Using a normal pressure gauge

How to use normal pressure gauge

A typical pressure gauge is as small as a pencil. It has a metallic exterior and plastic rods which will extend when you attach it to the tire stem. Air will rush out of the tire, in the process extending the plastic rod

The notches on the side of the gauge will indicate the amount of pressure exerted. You will also note that each 10th notch is slightly bigger than the ones before it, to make it easier for you when reading the pressure.

Assuming yours extends to a large 4 and a small 2, your PSI is 42, not 4.2.

Using an electronic pressure gauge

The beauty of using an electronic pressure gauge is that it delivers a highly accurate reading than the conventional gauge. All you have to do is turn on the device, press it against the nozzle and get the reading you need.

The challenge with this gauge however is that these gauges are more expensive than the conventional gauges. Other than that, you also have to make sure the gauge has been powered correctly.

If for example your power is running low, you might get inaccurate readings, or none at all, which basically puts your life and that of the other occupants in your car, and other road users you will come across, at risk.

To be on the safe side, keep checking the batteries from time to time. Other than that, you should have spare batteries in your car for emergencies.

Learning to use the gauge

It does not matter the kind of gauge that you have, you need to know how to use it, before you find yourself in an emergency situation and not know what to do. Once again, remember that proper inflation is important and safer for you when you are on the road than overly inflated or under-inflated tires, which could easily hydroplane.

Overinflated tires on the other hand will usually wear out so fast, and you will have to spend on replacements every so often. They also make it difficult for you to control the vehicle in a slippery environment.
