What term is used to indicate the specified tire inflation pressure in service information?

The specified tire inflation pressure in service information is referred to as the cold placard. This term is crucial because it denotes the recommended tire pressure when the tires are cold, meaning they have not been driven on for several hours. Proper tire inflation is essential for vehicle safety, fuel efficiency, and tire longevity.

The cold placard is usually found on a sticker located on the driver's side door jamb or in the owner's manual, providing the necessary information for maintaining optimal tire performance. It serves as a guideline for vehicle owners to ensure that tire pressures are within the manufacturer's specified range, which can greatly affect handling, stability, and overall vehicle performance.

Understanding this concept is important for anyone involved in vehicle maintenance, as adhering to the recommended tire pressure can help prevent issues such as uneven tire wear or reduced fuel efficiency.
