Thanks for your feedback. We understand your frustration and would like to offer a explanation about why you're seeing these differences in readings.
TPMS Technology Differences:
The variance you're observing is actually due to fundamental differences in how BMW's built-in TPMS and our external sensors measure tire pressure:
1. BMW's Factory TPMS:
Uses internal TPMS sensors
Measures pressure through tire deformation against the road
Does not account for temperature-induced pressure changes
Shows more consistent but averaged readings
2. Our External TPMS:
Provides real-time, dynamic measurements
Directly measures pressure at the valve stem
Accounts for temperature changes during riding
Shows true pressure variations as they occur
Typically reads slightly higher than internal sensors due to valve stem location
What This Means in Practice:
When you're riding, tire temperature increases, which naturally raises tire pressure. Our sensors show this real-time change, while BMW's system compensates for these fluctuations to show more stable readings.
This is not a problem or malfunction of our TPMS itself.
We hope this explanation helps clarify why you're seeing these differences in readings. If you have any further questions, please don't hesitate to reach out to us.
Best regards,
