Buyer’s guide: Factors to look at while buying a digital tire pressure gauge

Accuracy measurement – This should be your first criterion for buying a digital tire pressure gauge. Many products in the digital category look outstanding with their structure and colors. However, what matters the most is the accuracy in reading the air pressure by these units.

Make sure to purchase a model that is accurate and reliable in its reading. Take a comparison equipment such as a TPMS or another tire pressure gauge with you to check the accuracy on the spot before buying.

Ease of usage – Ease of use comes by default with almost all the digital tire pressure gauge models. Notwithstanding, consider a model that has an intuitive button layout that works on simple steps.

Digital tire pressure gauges display pressure results within a few moments of inserting them into the tire valve. 

Ensure there are no two ways other than these two steps and more importantly make certain the usage doesn’t require two hands to operate which is common with analog gauges.

Illuminated display – An illuminated display is the highlight feature of every digital tire pressure gauge. The display works wonders if you want to check the tire pressure in low light.

Digital tire pressure gauge display

Consider a digital tire pressure gauge equipped with an electronic LCD display that flashes the air pressure for ease of reading.

Range of pressure – The range of pressure could be subjective to personal use and preference. However, most digital tire pressure gauges possess a measuring range between 5 to 99 PSIs which is more than enough.

Nevertheless, it is important to consider the pressure range as it is directly correlated with the type of vehicle and the tires they have. The pressure range is also helpful in checking the compatibility of a pressure gauge.

Durability – Digital tire pressure gauges are made of materials resistant to dust, dirt, wear, and tear. Since these units are slightly heavier owing to the battery they are bound to fall and get damaged which can impact their accuracy.

Always look for a model that is made of durable materials to withstand demanding conditions, temperatures, and premature wear and tear.

Price – Price shouldn’t be a concern for most buyers since tire pressure gauges (of any type) are not too expensive. There is a price range from $7 to $50 and the features and types associated with the gauges form the crux for pricing.

Consider a product that offers primary features as standard without any fancy gimmicks (even though costly) as compared to the one that looks visibly attractive but lacks effectiveness.

Digital vs analog tire pressure gauge

Analog tire pressure gauge both hand usage
Generally, analog pressure gauges require both hands for usage

Here is the main difference between a digital and analog tire pressure gauge:

Digital tire pressure gaugeAnalog tire pressure gauge

As evident from the above comparison, both types of pressure gauges have their own advantages and cons. In the end, it depends on your personal requirements and preferences.

Regardless of the type of pressure gauge you prefer, it is important to note that these units require timely maintenance and calibration at least once every year.

The importance of tire pressure gauge

Tires are prone to losing air with consistent running. Underinflation is one of the major causes of tire blowouts.

Low tire pressure

The inflation abnormalities can also lead to deficiencies in the fuel economy and depreciate the lifespan of tires as well.

In the absence of a tire pressure gauge, the only way to check the tire pressure is by taking your vehicle to the nearest tire repair shop or a service center.

Again, such shops or service centers may not be easily accessible which means you could be running your vehicle on underinflated tires for too long attracting bigger problems.

All these difficulties and tire pressure consequences can be prevented with the help of a tire pressure gauge. These small equipments can detect and measure the inflation levels of tires at any location in no time.

Tire pressure gauges are easy to carry, store, and operate. They are not too expensive and their availability in different types makes them suitable for all types of vehicles and individuals.

With timely inflation and correct pressure, you can significantly improve the lifespan of a tire and save lots of money on tire repairs and replacements.

The benefits of digital tire pressure gauge

Portability – Digital tire pressure gauges are small equipments mostly resembling a glue gun structure that makes them very easy to carry.

Gun shape digital tire pressure gauge

The small size is an instrumental factor from a portability perspective. Generally, a glove box of any car is enough to store and take them anywhere.

Usage – Compared to an analog pressure gauge which needs additional hose or head attachments, a digital tire pressure gauge is extremely easy to use and works by just directly connecting with the tire valve to check the tire pressure.

Display – As the name suggests, digital tire pressure gauges have an LCD screen with backlit on some models that make reading the tire pressure visibly easy.

The digital display feature comes in handy to view the PSIs in the darker sections or at night time.

Accuracy – The accuracy of digital tire pressure gauges is more precise and close to the actual pressure a tire has.

The digital readout feature and the measuring capacity in multiple pressure units give these kinds of pressure gauges a preferable edge over their competitors.

How to use a digital tire pressure gauge?

Digital tire pressure gauges are known for ease of usage. Most of these units come with head valves (in different shapes) to accommodate types of tire valves.

Here is a small video showing how to use AstroAI digital tire pressure gauge:

As for the other tire pressure gauges, you can follow the below steps.

Steps to using a digital tire pressure gauge:

Before using a gauge to check the tire pressure, make sure the condition of the tires is suitable for testing.

It is highly recommended to check the pressure on tires when they are cold. This is only possible when the car has been standing idle for a long time.

Tires, when hot (after the drive) take time to release the built-up heat. You will not get accurate pressure readings no matter how good is your pressure gauge.

Once the condition of the tires becomes suitable,

  • Remove the valve cap from the tire and connect the pressure gauge nozzle to the tire valve.
  • Ensure there is no air leakage taking place once you have connected the instrument.
  • Select the pressure range you want to check (applicable only for devices having this feature)
  • Next, press the power button on the gauge and wait for the reading results (in some models you have to first press the power button and then connect the instrument to the tire valve). Go by the instructions from the manufacturer.
  • Keep the gauge connected till the readings are displayed on the screen
  • Disconnect the gauge and check the readings on the screen. Repeat all the above steps if you want to retake the readings. That’s it!

Tips to maintain a digital tire pressure gauge

The best way to maintain a digital tire pressure gauge is by following the maintenance instructions from the manufacturer. In addition –

  • Prevent the digital tire pressure gauges from water and other liquids. This may impact the digital capabilities of reading the tire pressure.
  • Store the digital tire pressure gauge in a cool and dry place. More than a cooled glove box a room-level temperature is better suitable for storage. Completely avoid keeping them in direct sunlight or temperature that is too hot.
  • When in use, ensure to hold and grip the instrument properly to avoid falling instances. Digital tire pressure gauges are prone to damage and misreading if frequently dropped on the ground.
  • Regularly inspect the performance of these gauges by comparing them with other similar devices. In case of accuracy, or abnormalities perform the calibration process by taking it to the manufacturer or professional calibrating center.

Conclusion

There is no doubt that digital tire pressure gauges are a great invention to check the air pressure of tires on the go.

The features of digital tire pressure are instrumental in maintaining correct tire pressure, evading early wear and tear, and increasing the fuel efficiency of a vehicle.

Digital display, pressure range, compact size, ease of usage, and ability to read the pressure in multiple units give a better edge to digital tire pressure gauges than a stick or analog ones.

While there may be slight variations between different digital gauges our best of three lists the ones that are most used, tested, and trusted by their users.
