Tyre pumps are one of those handy things you should always have, but often don’t. The next issue is never being able to remember your tyre pressures when you come to check them, Ring have come up with a nifty solution. A tyre gauge that stores your pressures, neat.
Basically it’s the same as any other tyre gauge, so you can measure PSI, BAR, kPA and kg/cm2. Along with that there is a tyre tread gauge built into the base, an LED light underneath and a swivel head.
The best part is being able to store the correct tyre pressures for the front and rear tyres though, it saves the faff of finding where they are located on your car, or in the log book.
Using two CR2032 under a screw hatch the whole screen is backlit blue, making the LCD easy to read no matter when you need it.
That swivel head makes it easy to find and attach the air valve too.
The whole unit is pretty weighty, feeling solid and made of metal. It also comes with a small soft pouch to keep it stored in.
I’ve used an older Ring tyre gauge for years, only throwing it away once I lost the small screw for it and had to glue the last battery in. This one is just as well built and will no doubt last years.
One major annoyance with any gauge is getting the angle right, especially if you have solid metal tyre valves. The swivel head on the RTG7 makes that a thing of the past, no matter where the valve is you can connect it easily to get a reading.
The tyre depth gauge is a little bit of an afterthought. You normally want to check your tyres to see if they’re still legal, so that’s 1.6mm, there’s no mark on the gauge to say where 1.6 is. The small metal bars are also pretty ambiguous. If you’re after precision it’s best to get an old school sliding gauge, but for a general idea of how much tread is left then it’s ok.
Storing the pressures is easy enough, simply hold down one of the arrows and the small car graphic will start to flash. Press up or down to set the correct pressure and then move on to the rear wheel. Sadly for us it seems like a line in the LCD display wasn’t quite working properly, so it made setting the rear pressure guesswork, but we got there in the end.
As always Amazon is your friend, but you can also find them on eBay and various other online stores.
