When verifying tire inflation, which source provides the recommended pressure?

• A. Placard on the bus
• B. Owner's manual
• C. Tire color
• D. Engine size

Answer: (A)

The recommended tire pressure is given on the bus placard. This placard is vehicle-specific and shows the exact cold inflation pressures for each tire position based on the bus model, axle, and expected load. It’s kept up to date by the fleet maintenance team, so inflating to those values ensures correct load handling, safety, and tire wear. The owner’s manual may offer general guidelines or reference a different vehicle, but it won’t reflect the current tires and configuration of this bus. Tire color and engine size have no bearing on the proper tire pressures.
