You hear the problem before it becomes one. TPMS Connect speaks your tyre warnings out loud, through your iPhone or straight through your car stereo. No windscreen monitor to mount. No dash light to notice. No glancing down at a screen while you are towing at highway speed. If a tyre drops below your set pressure limit, you hear it, in plain words, over the top of whatever you are listening to. Built in Australia for towing, touring and work vehicles. Voice alerts that reach you • Spoken warnings through your car stereo over Bluetooth • Also plays through your iPhone speaker if you are not connected • Tells you which tyre and what is wrong, so you know before you pull over • Cuts through music, podcasts and navigation • Works with your hands on the wheel and your eyes on the road Now on your car's screen too TPMS Connect supports Apple CarPlay. See live pressure, temperature and status for every wheel right on your car's own display. Full monitoring behind it • Live pressure and temperature for every tyre • Alerts when a tyre drops below or climbs above your limits • High temperature warnings, which can indicate a tyre or brake problem • Set your own pressure thresholds per vehicle • Cars, utes, 4WDs, caravans, camper trailers, motorhomes, boat trailers and work vehicles • Multi axle setups, including vehicle plus trailer combinations • Works over Bluetooth with no mobile reception needed Why it matters when you are towing A slow leak on a caravan tyre is easy to miss. Heat builds, the tyre lets go at speed, and you are on the shoulder of the highway with damage that costs far more than a set of tyres. A monitor you have to look at only helps if you look at it. A voice alert reaches you whether you are watching or not. You will need SAVR sensors This app works with SAVR tyre pressure sensors, sold separately at savr.me. Packs are available for single vehicles right through to vehicle and multiple trailer setups. Important safety note TPMS Connect is a monitoring aid, not a replacement for checking your tyres. Voice alerts depend on Bluetooth range, sensor battery, iPhone battery, and your volume and notification settings. Always carry out normal pre-trip checks. Support Email support@savr.me and you will hear back from a real person.
