How to Use a Tyre Pressure Gauge

Tyre pressure gauges are a vital piece of any rider’s kitbag. They are relatively inexpensive and help ensure your tyres are fit for purpose. Whatever the conditions, whatever the adventure that awaits, knowing if your tyre pressure is set for peak performance is a must.


Checking and maintaining correct tyre pressure is an important process to ensure your vehicle operates safely and to the highest standard. Having tyres correctly inflated also helps improve the tread life of each tyre.

Here at Venhill, all our cables and break lines help optimise driving performance. But even the best motorbike parts and accessories can’t compensate for incorrect tyre pressure.  

This mini guide delves into how to use a tyre pressure gauge and tips for getting started.

What is a Tyre Pressure Gauge?

A tyre pressure gauge is used to measure the pressure of the tyres of a car, motorbike or any vehicle that uses inflated tyres. Simply using your eyes to estimate tyre pressure isn’t accurate and could lead to misleading results. Gauges offer accurate and reliable readings and come in both standard or digital formats.

The gauge provides a unit measurement (PSI) to help drivers understand whether the tyres are under-inflated, over-inflated or just right.

PSI, pounds per square inch, is the measurement tyre pressure is recorded in. This number is used to interpret the pressure of the tyre.

PSI is a commonly used scale for pressure measurement, however alternative scales are also used and are sometimes in owners’ manuals, user guides and on pressure gauges themselves.
1 Bar = 14.5 PSI
1kg/cm² = 14.2 PSI

Depending on the vehicle, model, purpose and conditions, the optimal PSI will vary. This means there is no “recommended PSI” for everyone, instead, drivers and riders must refer to their own vehicle’s recommendations and documentation.

It’s worth noting that the recommended PSI is for cold tyres. If your tyres are hot this will increase the pressure so ideally take recordings when tyres are cold.

The benefits of having well inflated tyres are abundant. Poorly inflated tyres can lead to uneven treadwear, poor mileage, potential tyre failure and poor handlings. A pressure gauge helps combat all these potential issues by making it easy, hassle free and quick to ensure tyres have the right sort of pressure.

We would recommend checking your tyres every month at the minimum, as well as before any major journey or event. As temperature influences pressure, it’s also worth considering checking pressure as the seasons change.

How to Check Your Tyre Pressure

Follow the 4 simple steps below to check your tyre pressure:

  • Check Recommended PSI

Refer to your manufacturer’s manual or documentation to discover what the recommended PSI is for your specific vehicle. Experts may be able to give you a good idea, but the official recommendations from the manufacturer will be tried and tested. You may also find that different tyres need different pressure (for example, in a car, the front tyres may be different from the back). Note these recommendations down so you can refer to them when you test your tyres.

  • Consider Conditions and Purpose

Some manuals and manufacturer documentations may go into details regarding specific conditions and circumstances while others may keep it to one number. The weight a vehicle will take may mean tyre pressure would benefit from slight adjustments. For example, if the vehicle will take more weight, adding more pressure to the tyres helps combat this additional weight. However, if you’re going over lots of bumps and potholes, adding any additional pressure may make it feel bumper and increase the chance of tyre failure.

  • Attach Tyre Pressure Gauge to Tyre

Simply remove the valve cap and attach the tyre pressure gauge to the tyre. Make sure the gauge is attached evenly and securely. The gauge will display the PSI for each tyre. You can now refer back to the manufacturers recommendations to interpret whether the tyre is under-inflated, over-inflated or just right. Once you’ve finished, re-attach the valve cap to each tyre to ensure dirt and moisture don’t damage the valve.

  • Record Tyre PSI

It’s worth recording and storing the tyre pressure readings so you can refer to them next time. You may notice a certain tyre is deflating faster than others by doing this and can react appropriately. Having this sort of information readily available is also useful if you’re trying to understand potential issues with a vehicle. Your handling may simply be a result of tyre pressure and not anything else, so being able to review previous recording is a benefit.

The bleed valve enables the exact pressure to be established while the rubber shroud protects the dial gauge.

Once you have checked your tyres, you can then inflate any tyres as necessary.
