Naturally, tools such as these need to be as convenient as possible, and as space can be limited in cars, and especially with motorbikes, Ring has ensured that this tyre inflator is as compact as it can be, which also means it’s light, so it’s easy to move around the vehicle and top up the tyres. Additionally, there are multiple LED lights on the tool, so inflating tyres can be done at any time. Comes with a 3-piece adaptor kit for small inflatables such as sportsequipment and Presta bike valves. The pressure is usually shown in two formats: bar and psi. There are typically two sets of these. The lowest is for normal use, but you may well see another set of higher pressures for when the car is heavily loaded, increasing the weight that’s pushing down on the tyres. To help drivers save time, this tyre inflator also has a memory function, so the user can save different tyre pressures and activate them easily from the home screen, and it also has an auto-stop feature so there’s no risk of over inflating the tyre, which can be as dangerous as an under inflated tyre.

Complete with three adaptors - a Presta valve adaptor for road bikes, a sports ball adaptor, and a leisure adaptor for small inflatables, the Ring RTC4000 Tyre Inflator proves its versatility and utility for a range of inflation tasks. This cordless tyre inflator is not only effective in managing and maintaining tyre pressures but also proves to be a reassuring presence in the vehicle for emergencies. Smart storage case allows you to charge the inflator whilst still in the bag; with storage for cable Free Delivery is not available for Over-Sized parcels, such as Exhausts, Radiators & Headlamps - For details on these items please see the 'Oversized Items' section below. Given most people are used to tyre inflators being the size of a kids lunchbox with wires and cables, this small handlheld design might come as a surprise. It's about the size of a standard 50cl bottle of water and not much different in weight either. To charge it up took about three hours when it first arrived and since then we've been charging it up between uses.

With its innovative design and impressive features, the Ring RTC4000 Cordless Tyre Inflator confidently makes its mark as a versatile and powerful ally in any tyre maintenance routine. This cordless tyre inflator is a combination of efficiency and user-friendliness, turning tyre care from a mundane task into an effortless endeavour. Freedom and Flexibility I’ve used it to top up car and motorbike pressures and once to seat a stubborn tubeless tyre on a mountain bike. I like the screw-on fittings and long hose but generally think a digital gauge is easier to use than an analogue one. It’s a hefty bit of kit, but super speedy and surprisingly quiet. The RTC4000 is not just an inflator but also a smart tyre pressure management system. The digital auto-stop feature ensures the inflator ceases once the set pressure is achieved, while the integrated memory function can store up to four tyre pressures in PSI, BAR or kPA. In case of overinflation, a deflator valve is incorporated for precise pressure adjustments. Adaptability and Convenience

We timed how long it took to inflate a 15-inch tyre from 20-30psi, noting the pressures displayed before and after, plus the ambient and working noise levels. We also timed adding 5psi to a space-saver tyre, to bring it up to 60psi.

The best tyre inflators you can buy in 2023

Size is probably the most important thing. The smallest inflators are around 20 x 20cm, so you can leave them in your car without losing too much luggage space. The best don’t skimp on the length of the power lead and air hose, which makes it easier to reach all four valves. Most can be preset to stop inflating when your tyre reaches the correct pressure.
