Studies indicate that:

• technicians often diagnose camber wear as castor wear.
• technicians often diagnose toe wear as under-inflated tire wear.
• technicians often diagnose caster wear as toe wear.
• technicians often diagnose camber wear as toe wear.

Earlier (older model) vehicles:

• often used wide tread, small diameter tires.
• None of the answers listed
• often used wide tread, large diameter tires
• often used narrow tread, large diameter tires.

Technician A says all tire valve stems are removed and installed using the same process. Technician B says that some tire valve stems are part of the tire pressure monitoring system (TPMS). Who is correct?

All of the following statements about a tire pressure monitoring system are true, EXCEPT:

• . it is often referred to as a TPMS.
• it uses a warning light as a driver warning
•  it can be diagnosed with an appropriate scan tool. 
•  it can automatically stop a leak in a tire
