How do automatic tyre deflators work?

Set your desired PSI, attach them to your tyre valves, and they automatically stop deflating once the target pressure is reached.

What PSI should I use for beach driving?

For most beach driving, set your tyre pressure to 15–20 PSI to maximize traction and avoid getting stuck, with 16 PSI often cited as the ideal starting point. Lower pressures increase the tyre footprint, allowing your 4x4 to float over sand.

Can all four tyres be deflated at once?

Yes. The set includes four deflators so you can air down all tyres simultaneously.

Do these fit standard 4WD tyres?

Yes. They are compatible with standard Schrader tyre valves commonly used on 4WDs and most vehicles.

Are automatic tyre deflators reusable?

Yes, automatic tyre deflators are designed to be reusable. They are typically used for 4WD, off-roading, and camping to quickly lower tyre pressures for better traction
