AA Digital Tyre Pressure Gauge AA1634 - Easy to Use on Cars Motorbikes Vans Bicycles - Backlit LCD Screen - 0-100 PSI/0-6.85 Bar

As someone with run-flat tyres on my car, I am always conscious of checking my tyre pressure regularly to ensure a safe driving experience. After purchasing a portable car tyre inflator machine, I diligently followed my car's pressure guide when inflating my tyres. However, during a routine tyre replacement, the technicians were shocked at how my tyre pressure had exceeded the car's recommended levels. They suggested that I invest in a digital tyre pressure gauge to verify the accuracy of the inflator machine, as some machines can be unreliable. That's when I decided to purchase the AA Digital Tyre Pressure Gauge, and I have never looked back. Since adding this handy tool to my car maintenance routine, I now use it every time I inflate my tyres to ensure accurate pressure levels. The AA Digital Tyre Pressure Gauge is incredibly easy to use, with a clear digital display that provides precise pressure readings. Its compact design makes it convenient to store in my glove compartment, allowing me to have it on hand whenever I need it. The device has also proven to be durable and consistent in its performance. Overall, I am extremely satisfied with my purchase of the AA Digital Tyre Pressure Gauge. It has not only helped me maintain the appropriate tyre pressure in my car but has also given me peace of mind knowing that my tyres are safe and well-maintained. I highly recommend this digital tyre pressure gauge to anyone in need of a reliable, user-friendly solution for their tyre maintenance needs.

This is a handy little gadget - about the size of a mobile phone. Made of grey plastic with a soft, acid-etched finish, it is simple and quick to use, and provides a clear display in PSI or BAR. If you are long-sighted, be warned that the PSI and BAR unit display is minuscule. The device has just one button, which switches it on and off, and switches between PSI and BAR. The gauge has blue LED illumination, so you can use it in the dark without the need for a torch. It also switches itself off automatically after 60 or 90 seconds. Interestingly, when you switch it on, for a split second, several other units appear along the bottom of the display, but you can't select them. It comes in one of those indestructible plastic packages that you have to hack at with a steak knife to open. The packaging is quite big for such a small device, and seems to be designed for anti-shoplifter in-store display. The instructions are clear, but written by someone who has no idea what to do with an apostrophe. Oh dear. (You'd think the AA could afford to hire a technical author.) The instructions also include a nice legal-problem-avoidance clause for the AA, which basically says that the measurements the device makes are for guidance only and might not be very accurate. Hmmm. The device is easy to use, is robust, and will stand a few knocks. I have not found a serious fault with it.

Good product

I’ve been using the this tyre pressure gauge for over a year, and it has proven to be a solid and reliable piece of kit. Every time I’ve needed it, it has worked flawlessly, delivering accurate readings without fail. The build quality is excellent, and it feels durable and well-made. The digital display is clear and easy to read, even in low light, which is a big plus. It’s simple to use, compact, and fits easily into my glovebox, making it convenient for regular checks or emergencies.

As a motorcycle rider, I've found the AA Digital Tyre Pressure Gauge to be an essential tool for my rides. Its accuracy and ease of use are unmatched, providing quick readings that help me maintain optimal tyre pressure for safety and performance. The compact design means it fits perfectly in my topbox, ensuring it's always there when I need it. Despite the non-replaceable battery, its reliability and convenience make it a staple in my riding gear. A must-have for any rider who values the importance of regular tyre checks.

I bought this item thinking that with all these reviews it would be a reliable easy to use addition to my toolbox. I have to say I’m not impressed. 1) In this age of rechargeable batteries it seems so inconvenient and old fashioned to have to remove tiny screws to replace the battery. 2) I have difficulty applying the gauge to the tyre valve which means that by the time I have a pressure reading I have let a lot of air out of the tyre 3) the gauge only works intermittently. At times the blue light just flashes continuously so the gauge can’t be switched on. I’ve kept my non-digital gauge as a backup as I know it will always work with no changing fiddly batteries.

Cheap and easy to use. Appears to be accurate. Of course if you are left handed the displayed value is on the back of the gauge. But it does display long enough for you to turn it round to read it.

Nice handy addition to the tool box

Funciona bem

Slow in giving a reading Then the display keeps showing the same reading, even when ready to take a reading on the next tire so you’ve got to wait an extra few more seconds to shut off. I don’t recommend this product. Also the angle is very awkward.

Très satisfait de cet achat. J'ai acheté cette jauge AA pour confirmer l'exactitude de deux autres jauges que j'avais achetées précédemment. L’un est un manomètre à tube de Bourdon standard EN 837-1 (+/- 1% de la plage). L’autre est une jauge de pneu numérique LIDL (+/- 0,12 bar). Les trois manomètres indiquent des pressions pratiquement identiques dans la plage allant jusqu'à 3,5 bars. Je suis maintenant prêt à vérifier le réglage de la soupape de sécurité dans le cadre du service de ma chaudière de chauffage central.

Bought this digital AA pressure gauge in December 2025, to keep in my motorcycle jacket pocket, as it is a lot smaller than the mechanical pressure gauge that I bought several years ago. The AA gauge seemed to give correct readings for the first few months, but now it reads 1.95 bar for tyres that are actually 2.2, 2.4 or 2.5 bar. I know it is inaccurate because the mechanical pressure gauge is displaying the expected readings for all the tyres that I tested both gauges on. To rule out the batteries in the AA gauge as the problem I replaced all 4 of them (1x cR2032 and 3x LR44), but the unit is still reading 1.95 bar on a 2.4 bar tyre. The AA gauge is now useless to me. I dont think I still have the original box or any warranty slip it may have contained, so am not hopeful of getting a replacement. Does anybody have any similar experience? Or try to have their unit replaced?

Does exactly as advertised. Comes with a nice illuminated screen and mount which is very useful if you're using it at night or in a dark garage. It's also very compact and light, so fits nicely in the glove box. Perfect for track days or if you have cars or motorcycles that sit for long periods.
