A tyre pressure monitoring system (TPMS) shows your tyre pressure and temperature live, so you can spot a slow leak before it becomes flat. To choose one, count the tyres you need to cover (including the spare and any trailer), check what alerts it gives, and make sure you can add sensors later. Pair it with deflators and a gauge if you drive on sand, gravel or corrugations.
What a Tyre Pressure Monitoring System Does
Sensors fit to your tyre valves and send readings to a monitor or phone app. You see pressure and temperature without stopping to check each tyre. This matters when you're towing a caravan or camper, because a problem on the trailer can be hard to feel from the driver's seat.
How to Choose a Tyre Pressure Monitoring System
Tyres covered: Count your vehicle, spare and trailer tyres. A 4WD towing a camper needs more sensors than a solo ute.
Alerts: Look for pressure, temperature and leak warnings, plus a low sensor battery alert.
Monitor and app: Decide whether you want a dashboard monitor, a phone app or both.
Room to grow: Check whether you can add sensors later.
Sensor batteries: Find out what battery type the sensors use, so you can carry spares.
A TPMS Kit for Touring
The iCheck Tyre Pressure Monitoring System 5 Sensor Kit is listed with:
5 pressure and temperature sensors, enough for four wheels and a spare.
A solar-powered Smart Monitor with USB charging.
The iCheckTPMS app for Apple and Android.
Alerts for pressure, temperature, leaks, low sensor battery and signal loss.
Expansion to 10 tyres, and a 15-month manufacturer warranty.
The listing says it sets pressure benchmarks automatically when fitted to cold tyres. Its Off-Road Mode re-benchmarks after you air up or down.
Deflators and Gauges for Off-Road Driving
Lowering tyre pressure can improve traction on soft or rough surfaces. Automatic deflators release air until the tyre reaches a preset pressure and then stop.
| Quick Connect Deflators, 4 Pack ↗ | PLUS Quick Connect Deflator Kit ↗ | Digital Tyre Gauge with Tread Depth ↗ | |
|---|---|---|---|
| Fitting | Clip-on | Clip-on | Handheld |
| Range | 10-30 PSI | 10-30 PSI | 7.5-99 PSI |
| Includes | 4 deflators, storage tin | 4 deflators, digital gauge, tyre repair kit, 4 valve caps, 4 valve cores, valve removal tool | Gauge and hard case |
| Notes | Aluminium body, stainless spring | Gauge also measures tread depth | Tread depth 0-15mm, accuracy ±(1% + 1 LSD) |
| Warranty | 12 months | 12 months | 2 years |
A screw-on version of the deflators is also in the collection.
The deflators are rated at roughly 2 minutes to drop a 265/75R16 tyre from 40 to 20 PSI. That's a manufacturer figure, so real times vary with your tyres.
Use Them Safely
Recommended pressures vary with the tyre, load, vehicle and surface. Follow your tyre and vehicle manufacturer's advice.
Check pressures when the tyres are cold, because heat raises readings.
Reinflate before you return to sealed roads.
The gauge uses CR2032 button batteries. Keep them away from children and follow the warning on the listing.
A TPMS supports your regular checks. It doesn't replace them. Add it to your pre-trip checklist.
