Which of the following is a requirement for the outer wheel during a pre-trip inspection?

The requirement for the outer wheel during a pre-trip inspection is that it should be straight. A straight wheel is essential for proper handling and stability while driving. Any distortion, bending, or misalignment can affect the vehicle's ability to steer correctly and may lead to uneven tire wear or handling issues that compromise safety.

Ensuring that the outer wheel is straight also helps in maintaining the overall structural integrity of the wheel assembly, minimizing the risk of failure while on the road. A straight wheel contributes to optimal performance and safety, which are critical components in any pre-trip inspection checklist for commercial vehicles.
