External TPMS Guide: Picking the Right Tire Pressure Monitor
Alex and Emma explore aftermarket tire pressure monitoring systems with external cap sensors. They discuss pressure limits, wireless range, and crucial valve stem requirements.
In this episode

Wireless transmission range varies and long trailers often need signal repeaters
External caps require rigid metal valve stems to avoid high-speed rubber fatigue
Drivers with working factory direct TPMS can skip aftermarket kits entirely
