No. No app, no subscription. The kit works on its own.

The external sensors screw onto standard tyre valves, EV or not.

No. The external sensors in our kits screw onto the valve, so you fit them yourself. Internal sensors, which we quote by email, go inside the tyre, so a tyre shop fits and balances them.

The Aura's sensors screw onto your valve stems in under 10 minutes. No wiring.

Yes, they come paired to the screen. Screw them on and switch on.

External sensors are light and rarely need rebalancing. Internal sensors are balanced by the tyre shop when fitted.

Yes. External sensors unscrew, and the screen comes with them.

Aura kits come with anti-theft locking nuts that need the supplied tool to undo.

External: fit it yourself and swap the battery yourself. Internal: out of sight, but a tyre shop fits it and the battery usually can't be swapped. We quote internal sensors by email.

A booster carries the signal from the back of a long rig to the screen. Whether you need one depends on your rig. The Aura A6 has one in the box. For Guardian it's an add-on, $80, and takes the range from up to 30 m to up to 60 m.

Yes. Lower the low-pressure alarm before you air down, so it doesn't beep on the sand.

Yes. Put a sensor on each van tyre and they show on the same screen. The Aura A6 covers any 6 tyres, like a car and a single-axle van; Guardian goes to 26 tyres.

Yes, if your kit has a sensor for it, so count the spare when you choose. The Aura A6 can cover 4 wheels and 2 spares.

It's warning you: a leak, low or high pressure, high temperature, or a low sensor battery. Pull over when it's safe and check.

Usually a flat sensor battery or interference. Try a fresh battery first.

The sensor may be off or its battery flat. Make sure it's screwed down firmly so it presses the valve pin.

Heat from driving raises the pressure. That's normal. Set your pressures when the tyres are cold.
