Maryland State Inspection - Technical Practice Exam

The definition of a "defective" tire according to Maryland inspection standards is based on the condition of the tire tread. A tire that has tread depth below the legal limit or shows visible cord presents significant safety risks, such as reduced traction and increased likelihood of blowouts. Both inadequate tread depth and visible cord indicate that the tire is no longer able to perform effectively, especially under wet or challenging driving conditions, which is why they are classified as defective.

Proper inspection practices require that tires must have sufficient tread depth to ensure safe handling, braking, and overall vehicle stability. Thus, this criterion aligns with the standards set for vehicle safety inspections, which prioritize the safety of the driver, passengers, and other road users.
