Live tire pressure and temperature on iPhone and CarPlay. Alerts for leaks, low pressure, and heat.
TST SafeSense turns your phone and CarPlay into a real-time tire health dashboard for trucks, trailers, motorhomes, and fifth wheels.
Pair the SafeSense Hub once, sync each sensor to its tire, and watch live pressure, temperature, and sensor battery for every wheel — including duallies and the spare. The app spots problems before you feel them on the road: low-pressure warnings before a slow leak strands you, danger-level alerts before a blowout, and high-temperature flags before a bearing fails.
KEY FEATURES
• Live status for every tire — PSI/BAR or kPa, °F or °C
• Per-axle thresholds so trailer pressures don't trigger truck alerts
• Low-pressure warnings, danger alerts, high-temperature flags, low-battery, and offline-sensor notifications
• Hub out-of-range detection on app launch
• Spare-tire monitoring
• Up to four trailers per truck, with optional secondary tow vehicle
• Multi-user Hub access — share read-only or admin with your partner or fleet
• CarPlay support — see tire status without taking your eyes off the road
• Alert history with one-tap navigation to the affected tire
• Light, Dark, and System theme
• Face ID / Touch ID quick unlock
• Imperial and Metric units
