Under what condition should a vehicle be rejected related to radial tires?

• A. If there is a tube type radial tire without stem markings
• B. If the tire is over 10 years old
• C. If the tread is uneven
• D. If they have a low air pressure

Answer: (A)

A vehicle should be rejected for radial tires that are tube type without stem markings because this indicates a lack of proper identification and traceability. Stem markings are essential for ensuring that the tires meet safety standards and specifications. Without them, it is difficult to ascertain important information about the tire, such as its production date and manufacturer specifications, which can directly impact the safety and performance of the vehicle. While other conditions may also lead to a rejection—such as the tire being over 10 years old, uneven tread, or low air pressure—these situations typically focus on immediate safety risks or compliance with general tire standards. The absence of stem markings is a more definitive regulatory issue, highlighting the need for proper labeling and identification to ensure safety on the road.
