The STONEGO Solar Car TPMS monitors the real-time tyre pressure and temperature of all four tyres simultaneously and displays the data on a colour LCD screen mounted on the dashboard. It charges via a built-in solar panel with USB backup charging, eliminating the need to tap the cigarette lighter socket for permanent power. The system is available in two configurations: an external sensor set for DIY self-installation, and an internal sensor set for more stable, more accurate readings installed by a tyre centre. Wireless sensor communication requires no wiring between the sensors and the display unit. The system activates automatically via an intelligent shock detection boot when the vehicle starts moving, requiring no manual on/off switching.
Key Features and Benefits
The display unit charges through the integrated solar panel during daylight hours and accepts USB power as a backup, making it a self-contained unit with no dependency on the 12V socket. Real-time pressure and temperature readings for all four tyres are shown simultaneously on the colour LCD display in a clear digital format. The alarm system triggers audible and visual warnings for low tyre pressure, high tyre temperature, tyre leakage, and low sensor battery conditions. The intelligent shock boot function wakes the system automatically when the vehicle begins moving and powers it down after the vehicle stops, removing the need for a manual power switch. Wireless sensor pairing requires no cables between the sensors and the display unit, making installation straightforward on both internal and external sensor configurations. Advanced chip sensors are designed to be compatible with approximately 98 percent of passenger vehicles on the market. Both internal and external sensor variants are IP67 rated for dust and water resistance. The external sensor battery is user-replaceable using the included wrench tool, extending service life without requiring professional intervention.
Material, Finish and Colour Options
Material: ABS housing for the display unit; IP67-rated sensor casings
Finish: Matte black display unit body with colour LCD display panel
Colour Options: Black (single option)
Product Compatibility
Universal fitment. Compatible with approximately 98 percent of passenger vehicles, SUVs, hatchbacks, sedans, wagons, and light commercial vehicles with standard tyre valve stems. The external sensor set fits over the existing valve stem caps without tyre removal. The internal sensor set replaces the existing valve stem internally and requires fitment by a tyre centre or automotive workshop. Both configurations operate on the same display unit; only the sensor type differs between the two purchase options.
Two configurations available: External Sensor Set (self-install, user-replaceable batteries) and Internal Sensor Set (workshop installation required, longer battery life, greater temperature resistance).

Installation Notes and Special Functions
External Sensor Set: Remove the existing valve cap from each tyre and thread the external sensor directly onto the valve stem in its place. No tyre removal or workshop visit required. The anti-theft design resists casual removal. To replace the sensor battery when depleted: remove the dismantling gasket, unscrew the sensor shell using the included wrench, remove the spent battery, and insert a replacement.
Internal Sensor Set: Internal sensors are installed inside the tyre by replacing the standard valve stem. This requires tyre removal and refitting at a professional tyre centre or automotive workshop. Internal sensors provide greater accuracy, a wider working temperature range (minus 40 to plus 125 degrees Celsius), and a longer battery life of approximately 5 years compared to the external variant. Professional installation is mandatory for the internal sensor configuration.
Once sensors are installed, mount the solar display unit on the dashboard using the included fixed sticker, ensuring the solar panel faces toward the windscreen for maximum solar charging exposure. The system powers on automatically via the intelligent shock boot when vehicle movement is detected and does not require a manual on/off switch.
