Well, ensuring your tyres have the optimal amount of air inside improves the efficiency with which they rotate, improving your economy and saving you money in fuel. You can check tyre pressures at a petrol station using an air compressor, but using a tyre pressure gauge is both quicker and easier and can be done at home or at the roadside. Everyone from Toyota to Porsche sells hybrids these days, but which models are best and which should you avoid?

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. There are a range of tyre pressure gauges that come in various shapes and forms, from analogue to digital, and keyring-sized to glovebox-sized.

Or if you are using an analogue gauge, you can use the built-in deflator button to bring the pressure to the correct amount. Even so, if having a compact unit that you can keep in the car is a factor – and you don’t need very high pressure readouts – this is a great little gauge that feels well made and is a doddle to use. If you need to inflate your tyre, attach a suitable pump to the valve and increase the tyre pressure in small increments. Reasonably easy to use but worth thinking as to how you are going to use it as if you have particularly difficult access to valve hen bear in mind you have to push this device on to valve.

To use, the pressure gauge must be placed firmly over the tyre valve, once the ‘On’ button is pressed the gauge must be held on the valve until the reading is displayed. It comes complete with a rotating chuck that makes it easy to get the gauge onto the tyre valve, too, but the rubber hose is chunky and can make the gauge awkward to use, because it’s harder to manipulate.This nifty digital tyre pressure gauge provides tyre pressure reading in PSI and BAR with blue back-lit LCD display. Some drivers will love this product’s pistol grip, and it worked well – especially in low light as the blue LED illuminates around the chuck to ensure locating the valve is simple. The extended, rotating neck makes awkward valves easy to reach, while the chrome-plated finish and heavy-duty rubber give it an extra-durable feel. You can quickly and easily check your tyre pressures with this compact digital tyre pressure gauge without having to visit a petrol station.

The AA gauge is very similar to the other digital gauges here, but it measures pressure only in psi and bar. This nifty digital tyre pressure gauge provides tyre pressure reading in PSI and BAR with blue black-lit CD display. Please complete the purchase (or remove the quote – don't worry it's still available in My Account) before adding these additional items. This handy digital tyre pressure gauge has an ergonomic design and blue back-lit LCD display, with an automatic on/off button which displays PSI and BAR readings.Having the correct tyre pressure can help provide better safety, longer tyre life and better fuel consumption. The dial isn’t as easy to read as those of some rivals, but it is glow-in-the-dark, which is useful, and can be used even for high-pressure tyres.
