How the system works
A high-level system map. Component roles and exact circuit behavior vary by vehicle.
- 01Tire load supportTire carries load through inflation and structure
- 02Road contactTread creates road contact
- 03Wheel mountingWheel locates and mounts the tire
- 04Hub rotationHub supports rotation
- 05Pressure monitoringTPMS warns about pressure or system concerns
Major components in context
Carries load and creates the road contact patch
System contextMounts the tire and attaches it to the hub
System contextSupport controlled wheel rotation

TPMS warning light
Check actual cold pressure against the vehicle placard before diagnosing the monitoring system.
Follow the diagnostic pathSYMPTOMTire keeps losing air
Check cold pressure and tire condition before resetting TPMS.
Follow the diagnostic pathSYMPTOMSpeed-related vibration
Inspect damage, mounting, balance, runout, hub, and suspension conditions.
Follow the diagnostic pathSYMPTOMUneven wear or pull
Inspect pressure, tire condition, rotation history, looseness, and geometry.
Follow the diagnostic pathA system-level diagnostic method
Inspect every tire before driving
Use the vehicle placard rather than the sidewall maximum
Record speed, braking, surface, and temperature pattern
Inspect wheel mounting, runout, damage, and wheel-end condition
Confirm TPMS compatibility and registration requirements from exact information
Evidence worth preserving
Placard-based cold pressure
Tread, sidewall, age, and damage condition
Balance, runout, and road-force evidence when needed
TPMS sensor data and registration state
Use the VIN, installed equipment, current manufacturer information, and applicable safety rules.
Safety and professional boundary
Tire failure and support warning
Do not drive on a tire with exposed structure, severe damage, rapid air loss, or unsafe inflation. Use approved support and correct wheel-fastener procedures.
