X91 Off-Road TPMS & Inclinometer – Tire Pressure, GPS Speed & Slope Meter All-in-One

The AOMOSUR X91 is a dedicated off-road driving instrument that combines a Tire Pressure Monitoring System (TPMS) with real-time vehicle pitch & roll angle measurement and GPS driving data.
Designed for 4×4, SUV, pickup and off-road vehicles, X91 helps drivers monitor tire safety and vehicle attitude on uneven terrain, steep slopes and long-distance overland routes. \n

Built for Off-Road & Overland Driving

\n

Off-road driving puts extreme stress on both tires and vehicle stability. Uneven terrain, side slopes, steep climbs and high surface temperatures can quickly turn into safety risks.
The AOMOSUR X91 is engineered specifically for these conditions, providing tire health data and vehicle attitude information in one dedicated dashboard display.

Off-Road TPMS – Tire Safety Comes First

\n

X91’s primary function is real-time tire pressure and tire temperature monitoring.
During off-road driving, incorrect tire pressure can reduce traction, increase sidewall damage or cause overheating at speed.

\n

The system continuously monitors each tire and provides audible alarms for:

\n \n

\n
• \n

  High tire pressure

  \n
\n
• \n

  Low tire pressure

  \n
\n
• \n

  High tire temperature

  \n
\n
• \n

  Sensor low battery

  \n
\n
• \n

  Sensor malfunction

  \n
\n

\n

Pressure units (BAR / PSI) and temperature units (°C / °F) can be adjusted to match regional and driver preference.

\n \n

Vehicle Attitude Monitoring – Pitch & Roll Awareness

\n

X91 features a built-in digital inclinometer displaying:

\n \n

\n
• \n

  Pitch angle (front & rear): –40° to +40°

  \n
\n
• \n

  Roll angle (left & right): –40° to +40°

  \n
\n

\n

This information is critical when navigating:

\n \n

\n
• \n

  Side slopes and camber roads

  \n
\n
• \n

  Steep ascents and descents

  \n
\n
• \n

  Uneven trails and rock crawling sections

  \n
\n

\n

A scale + numeric display allows quick visual judgment without distraction.

\n \n

GPS Driving Data for Remote Routes

\n

For off-road and overland travel where onboard vehicle data may be limited, X91 integrates GPS / Beidou dual-mode positioning, providing:

\n \n

\n
• \n

  GPS speed

  \n
\n
• \n

  Altitude

  \n
\n
• \n

  Latitude & longitude

  \n
\n
• \n

  Compass direction

  \n
\n
• \n

  Satellite signal status

  \n
\n
• \n

  Time display (auto calibrated)

  \n
\n

\n

The system works independently and does not rely on OBD or mobile apps.

\n \n

Off-Road Safety Alerts

\n

To support long-distance and night driving, X91 includes:

\n \n

\n
• \n

  Customizable overspeed alarm

  \n
\n
• \n

  Fatigue driving reminder

  \n
\n
• \n

  Audible alerts with sound on/off control

  \n
\n

\n

These features help reduce risk during extended off-road journeys.

\n \n

Vehicle-Grade Power & Rugged Design

\n

\n
• \n

  Wide power input range: DC 11.5V – 30V (12V / 24V vehicles)

  \n
\n
• \n

  Auto power on with vehicle start

  \n
\n
• \n

  Automatic sleep when parked

  \n
\n
• \n

  Ambient light sensor for automatic screen brightness adjustment

  \n
\n

\n

The housing uses ABS + PC high-temperature resistant material with a carbon-fiber appearance, designed to withstand vibration, heat and continuous vehicle installation.
