This solar tire pressure monitoring system (TPMS) is engineered for SUV, pickup and off-road vehicles. Four wireless sensors are mounted on the valve stems or inside the tires and report real-time pressure and temperature to a solar-powered LCD display mounted on the dashboard or windshield, so the driver sees all four wheel readings at a glance without any wiring work.
Off-road use puts tires through a wide spread of load, terrain and ambient temperature. The receiver therefore covers a 0–8 bar (0–116 PSI) measuring range, keeps the alarm threshold user-adjustable, and the sensor electronics are rated from -40°C to +125°C so that highway heat, desert sun and cold-morning starts do not interrupt the data link.

Screwed onto the existing valve stem with the supplied lock nut. No tire removal, no wheel balancing, roughly three minutes for all four wheels — the version most retail and DIY customers choose.
Fitted inside the wheel with the supplied clamp-in valve stem, which protects the sensor from trail debris and theft, and extends battery life to five years or more. Requires a tire changer and a re-balance after fitting.

A1: It is a universal aftermarket system for SUV, pickup, light truck and off-road vehicles that run on rubber valve-stem wheels. The 0–8 bar range covers passenger-car and light-truck placard pressures.
A2: No. Sensors are pre-set at the factory and the receiver matches them automatically, so wheel positions do not need to be re-taught after a tire rotation.
A3: No wiring is required. The display is charged by its solar panel, and the mini-USB slot is there for indoor or low-light charging.
A4: 100 sets. Paid samples are available for evaluation before a bulk order.
A5: Yes, OEM and ODM are both available. Send the logo artwork and the packing layout you need and we will quote the tooling cost.
A6: 10–18 working days after the order is confirmed, depending on quantity and sensor version.
A7: EXW, FOB Shenzhen and CIF are accepted. Payment is by T/T, L/C, Western Union or .
A8: One year. Send a photo or video of any faulty unit and we will troubleshoot online first, then repair or replace it once the defect is confirmed.
