Ensuring that your tyres are at the right pressure can not only help you to avoid potential hazards, but also save your money on fuel. In order to ensure a smooth ride when driving a heavily loaded vehicle the tyres will require higher pressure. When you drive with a flat tyre you can damage your vehicle. Therefore, it is utterly necessary that you make sure that your tyres are correctly inflated on a regular basis. For that reason, having a portable gauge is essential. The most common gauge has a dial to indicate the tyre pressure while digital gauges have an electronic display. Operating such a device is very simple.

Firstly, you need to remove the cap from the tyre valve steam. Then, press the gauge onto the tyre`s valve steam and wait until the device needle moves to a certain number. Read the pressure and release the gauge. Once you’ve finished, re-attach the valve cap to each tyre.

Bear in mind to conduct measuring on cold tyres, as their pressure can change after a warming up drive. A sticker with the right values from the vehicle producer is usually located on the door sill. Otherwise, you can refer to the vehicle manual.

Most tyre pumps also have built-in gauges for measuring the tyre pressure, which is convenient during their inflation, while a portable gauge can help you to check each tyre easily and quickly. Modern gauges have a robust design and a dial with a few scales on (including PSI, bar).

Choosing tips

A digital gauge provides more exact readings (even up to 0.1 PSI), however, it also requires a battery, so don’t forget to replace it in due time. A case will be convenient for storing a gauge – often these devices are sold with a case. Choose a gauge with a proper measuring range, depending on the vehicle you own. As an example, a gauge with around 30 PSI will fit most vehicles, while a gauge of 80–100 PSI will fit heavy-duty, high-pressure wheels. Additionally, there are gauges with a built-in inflator, which can also help you to reduce wheel pressure in case of overinflation.
