Where can the correct tire inflation pressure typically be found for a passenger vehicle?

The correct tire inflation pressure for a passenger vehicle is most commonly found on a placard located on the driver's door. This placard is placed there by the vehicle manufacturer and provides essential information tailored to that specific vehicle, including the recommended tire pressures for both the front and rear tires. This information is crucial for ensuring optimal vehicle performance, safety, and tire longevity.

While tire sidewalls do have information about maximum pressure, this does not accurately reflect the optimal pressure suggested by the manufacturer, which is what drivers need for everyday use. The owner's manual contains a wealth of information, including maintenance guidelines and specifications, but the placard is typically the quickest and most accessible reference for tire pressure. Fuel filler caps occasionally have other information, but it's not a standard location for tire inflation pressure. Therefore, the driver's door placard is the most reliable source for this specific information.
