The tire pressure specification printed on the sidewall of the tire indicates what?

The tire pressure specification printed on the sidewall of the tire indicates the maximum inflation pressure. This pressure is the upper limit that the tire can safely withstand. Exceeding this pressure can lead to tire failure, while operating below this pressure can negatively affect performance, handling, and tire wear.

Understanding this specification is crucial for maintaining tire health and ensuring vehicle safety. It's important to note that for optimal performance and safety, drivers should refer to their vehicle's owner's manual or the sticker usually found on the driver’s side door jamb for the recommended cold inflation pressure rather than solely relying on the maximum pressure indicated on the tire itself. This recommended pressure is specifically determined for that vehicle's weight and load requirements, and maintaining it can help enhance fuel efficiency and extend tire life.
