Final answer:
The correct statement is that the tire exerts an outward force on the rim due to the air pressure inside, creating the necessary friction to prevent slipping.
Step-by-step explanation:
The correct statement regarding inflation of a radial truck tire on a single piece rim is that the tire exerts an outward force on the rim due to the pressure of the air inside. This force creates the necessary friction between the tire and the rim to prevent the tire from slipping off.
When the tire is inflated, the air pressure pushes the tire sidewalls against the rim, creating a secure connection. This ensures that the tire stays in place during driving and allows the wheel to support the weight of the vehicle.
It's important to note that proper tire inflation is essential for maintaining optimal performance and safety on the road. Overinflated or underinflated tires can lead to uneven wear, decreased handling, and increased risk of blowouts. Therefore, it is recommended to follow the manufacturer's recommended tire pressure.
