Tyres, Air & Compressors — FAQ
How do I choose the right air compressor for my 4WD?
Match the compressor to your tyre size and how quickly you want to reinflate after a day off-road. Larger 4WD and light truck tyres benefit from a higher output unit such as a heavy duty 12V compressor rated to 150 to 160 PSI, while smaller vehicles and occasional top-ups are well served by a portable inflator. Look for a built-in gauge, a duty cycle that suits back-to-back tyres, and fittings that connect easily to your valve stems.
What is the difference between a rapid deflator and an automatic screw-on deflator?
A rapid deflator with a gauge lets you remove the valve core and drop pressure quickly, then monitor and set your exact PSI by hand. Automatic screw-on deflators are preset or adjustable to a target pressure and stop on their own, so you can work across all four tyres at once. Choose rapid units for speed and control, or automatic kits when you want a hands-off, repeatable airing-down process.
Do I need a moisture filter or water trap with my compressor?
A moisture filter and water separator help keep water and oil out of your air line, which is useful for air tools, tyre work, and cleaner inflation. They mount inline between the compressor and your outlet and are handy in humid Australian conditions. Fitting one is a simple way to protect downstream equipment and keep your air supply drier.
Are tyre pressure monitoring systems worth adding to a touring setup?
A TPMS gives you live pressure and temperature readings so you can spot a slow leak or overheating tyre before it becomes a problem on remote tracks. Wireless and app-connected systems display each corner in real time and are especially reassuring when towing or running lower pressures off-road. They pair well with a quality gauge and compressor to round out your tyre management kit.
How accurate should my tyre pressure gauge be and how do I look after it?
Reliable pressure setting starts with a good gauge, so a digital unit reading up to 250 PSI with a clear display makes airing up and down far easier. Store gauges and deflators clean and dry, keep grit out of the valve fittings, and give them a gentle check against a known reference now and then. Treating your gauge as a precision tool helps keep your readings consistent over time.
