CHIGEE TPMS readings may differ from the BMW factory TPMS (RDC) display. BMW's RDC shows tire pressure temperature-compensated to 68 °F (20 °C), while CHIGEE sensors show the currently measured pressure.
System Comparison
BMW Factory TPMS: Temperature-Compensated Reading
BMW's factory TPMS uses an internal sensor system that:
Is mounted inside the tire
Uses processed data that filters out pressure changes from temperature fluctuations
Shows relatively stable readings across different riding conditions
CHIGEE TPMS: Dynamic Measurement
CHIGEE's TPMS provides real-time, dynamic measurements using a sensor system that:
Is mounted outside the tire (external sensors) or inside the tire (internal sensors)
Shows natural pressure fluctuations as temperatures change during riding
During rides, as tires warm up, pressure increases
When stopped and cooling, pressure decreases
Why Readings Differ
Measurement Philosophy
CHIGEE: Displays real-time, unfiltered data, capturing natural pressure changes as the tires heat up during riding.
BMW: Displays processed, stabilized readings that filter out temperature-related variations.
