【Professional Tire Pressure Monitoring System - 24/7 Real-Time Tracking】 Keep your tires safe with our advanced tire pressure monitoring system (TPMS) featuring ±2 PSI / ±3°F accuracy. Military-grade sensors update every 0.3 seconds (3x faster than standard systems) to track pressure and temperature simultaneously. The LCD display refreshes every 6 seconds, giving you instant alerts for leaks or overheating—perfect for RVs, trucks, and highway towing. Supports PSI/BAR unit switching for universal compatibility with all vehicles.

【6 Smart Alarms + Custom Thresholds】 Our TPMS sensors set of 4 deliver 6 advanced alarm modes: High/Low Pressure, High Temperature, Sensor Disconnection, Low Battery, and Sensor Fault. Easily customize alert thresholds (0-87 PSI / 0-6 BAR) via the LCD menu—perfect for adjusting to heavy loads or off-road conditions. Supports instant unit switching between PSI/BAR and °F/°C. Ideal for RVs, trucks, and SUVs under 50ft.

【Solar/USB Dual Charging & Smart Power Management】 This advanced TPMS features dual charging: Solar-powered for eco-friendly operation + USB-C fast charging when sunlight is low. The system intelligently powers off 3 minutes after engine shutdown and auto-reactivates on ignition—saving energy without compromising safety. Our TPMS sensors (set of 4) use long-lasting CR1632 batteries (included) with:✓ 6+ months per battery (with smart sleep mode).✓ 2-year total lifespan.✓ Easy battery replacement. Perfect for RVs, trucks, and trailers—always ready when you are!

【2-Minute Hassle-Free Installation】 5-Step External Tire Sensors Setup – No tire removal! 1.Power on display (hold for 3 seconds). 2.Screw hex nuts onto all 4 valve stems. 3.Install sensors in correct positions:LF → RF → LR → RR. 4. Firmly tighten nuts (anticlockwise) to prevent vibration loosening. 5.Soap water test ensures leak-free seal.Critical Note: Hex nuts are mandatory – They provide:✓ Anti-vibration (prevents sensor loosening at high speeds).✓ Secondary seal (reinforces air-tight connection).✓ Valve protection (shields stems from damage).

【Auto-Adjusting Color LCD + Reliable Support】 Our tire pressure monitoring system features a high-resolution color LCD that automatically adjusts brightness—perfect visibility day or night with zero glare. No more squinting! If you have any further questions or need assistance, our professional customer support team is always available to help.
