What can cause pressure loss?
Pressure loss can come from more than one tires & wheels branch. Operating conditions, warning behavior, scan data, and physical tests are needed to separate the supported cause from look-alikes.
Plausible causes
- Tire, wheel, pressure, or rotating-assembly concern
- Pressure loss or structural tire damage
- Balance, runout, road force, hub, or bearing
Useful next checks
- Check pressures cold against the driver-door placard, not the sidewall maximum. Photograph tread, sidewalls, wheel, TPMS behavior, and record the speed and where vibration is felt.
- Leak, tread, sidewall, wheel, and torque inspection
- Radial/lateral runout and correct-centered balance
