Questions, answered.
What is a Bluetooth tyre pressure monitoring system?
A Bluetooth TPMS uses sensors fitted to your tyre valves to send pressure and temperature readings straight to an app on your phone. SAVR shows those readings in the TPMS Connect app and warns you by voice when a tyre moves outside the limits you set. There is a full explainer in the complete guide to tyre pressure monitoring systems.
Which sensor pack should I buy?
Count the tyres you want monitored, spares included, and match that number. Packs come in 2, 4, 6, 8, 10, 12, 14 and 16 sensors. The 8 sensor pack is the most popular because it covers a tow vehicle and a tandem-axle van together. The larger packs suit fleet vehicles and rigs towing multiple trailers.
Will SAVR fit my vehicle or caravan?
SAVR sensors screw onto standard Schrader tyre valve stems, which is what the vast majority of cars, 4WDs, caravans and trailers in Australia use. If your vehicle has an unusual valve design or limited clearance, check the compatibility guide first.
Do I need a booster or repeater?
No. SAVR connects directly to your phone and needs no booster, relay or repeater on any pack size. Sensors transmit up to 15 metres and have been tested on caravans up to approximately 25 feet. There is no extra box to mount, wire, charge or power.
Does SAVR work with Apple CarPlay and Android Auto?
Yes. Spoken alerts play through your vehicle speakers while you use Apple CarPlay or Android Auto. Live tyre readings stay in the TPMS Connect phone app and do not take over the CarPlay or Android Auto display. There is more detail in our article on using SAVR with CarPlay and Android Auto.
Does the app work while my phone is locked?
Yes. Once the app is open and the phone permissions are enabled, SAVR keeps monitoring in the background while your phone is locked. You do not need to sit there watching it.
Can I monitor my tow vehicle and caravan at the same time?
Yes. The 6, 8, 10, 12, 14 and 16 sensor packs cover combinations of tow vehicles, caravans, trailers and spare wheels. You can set separate profiles and pressure ranges for each setup, since a van rarely runs the same pressures as the car pulling it.
How long do the sensor batteries last?
Each sensor uses a replaceable CR1632 battery, typically lasting 12 to 24 months depending on use, temperature and battery quality. They are sold at automotive stores, battery retailers and most supermarkets, and the app warns you before one goes flat.
Do I need a mechanic to install it?
No. The external sensors screw onto the valve stem and are fitted yourself, usually in about five minutes, using only the spanner in the box. No mechanic and no tyre shop.
Can the sensors be stolen?
Every pack includes anti-theft lock nuts and a fitting tool. Once locked on, the sensors cannot simply be unscrewed by hand at a campsite or a car park.
What is the difference between external and internal TPMS sensors?
External sensors screw onto the tyre valve and can be fitted, moved and replaced without removing the tyre. Internal sensors sit inside the wheel and normally need a tyre shop to install and service. There is a full comparison in our external versus internal TPMS guide.
What should I do if a sensor stops reading?
Most reading issues come down to a battery, an app permission or a pairing setting, and all three are quick fixes. Follow the TPMS troubleshooting guide, or email support@safetysam.au and you will get a real answer.
