How AirCheck BLE Works

Schrader Valves Part Number 29500-2 uses BLE technology to send tire data to a smartphone app, even when the app is running in the background. The system is built to keep you informed on connected sensors so you can react quickly to pressure loss, rising temperature, or low sensor battery status. Part Number 29500-2 is a practical retrofit solution for trailer owners who want direct tire monitoring without factory-installed TPMS.

Compatible vehicle fitment includes long-tail applications such as Fits 2015-2026 Ford F-150, N/A; Fits 2016-2026 Toyota Tacoma, N/A; and Fits 2016-2025 Ram 2500, N/A when used in supported trailer, RV, and tow-behind monitoring setups. It also aligns with towing and travel applications for vehicles like the Chevrolet Silverado 1500 and Toyota Tundra.

Common Problems It Helps Solve

• Loss of tire pressure on trailers, campers, and RVs during travel
• Delayed awareness of tire temperature changes
• Difficulty checking multiple wheel positions manually
• Low sensor battery visibility during long trips
• Need for a retrofit TPMS solution on towable equipment without factory monitoring

Installation Notes and Tips

Install the clamp-in sensors at the wheel and secure the range extender using the supplied mounting screws. The sensors are pre-programmed and not programmable, so setup is focused on pairing the system to the app and confirming sensor locations. Follow the recommended nut torque of 71 in-lbs (8 Nm) during installation, and charge the range extender with the included USB cable before use.

Quality Assurance

Schrader Valves backs this TPMS retrofit kit with a 2-year manufacturer warranty. The kit includes a wheel-mounted sensor design, nickel-plated brass core material, and the components needed to support reliable trailer tire monitoring in everyday towing conditions.
