How the system works
Follow energy, material, information, and mechanical force through the system before focusing on a single component.
A high-level system map. Component roles and exact circuit behavior vary by vehicle.

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
System contextSupports pressure monitoring on direct systems
Open component →Retain inflation and allow service
System contextSymptom patterns and first direction
TPMS warning light
Check actual cold pressure against the vehicle placard before diagnosing the monitoring system.
Follow the diagnostic path →SYMPTOMSpeed-related vibration
Inspect damage, mounting, balance, runout, hub, and suspension conditions.
Follow the diagnostic path →SYMPTOMUneven wear or pull
Inspect pressure, tire condition, rotation history, looseness, and geometry.

Inspect every tire before driving
Use the result to support or reject a cause group before moving to a more invasive test.
Use the vehicle placard rather than the sidewall maximum
Use the result to support or reject a cause group before moving to a more invasive test.
Record speed, braking, surface, and temperature pattern
Use the result to support or reject a cause group before moving to a more invasive test.
Inspect wheel mounting, runout, damage, and wheel-end condition
Use the result to support or reject a cause group before moving to a more invasive test.
Confirm TPMS compatibility and registration requirements from exact information
Use the result to support or reject a cause group before moving to a more invasive test.
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.
