What is a critical aspect of inspecting the tires during a pre-trip inspection?

Assessing the tread depth and pressure is vital during a pre-trip inspection because these factors directly affect vehicle safety and performance. Proper tread depth ensures adequate traction, which is crucial for preventing slip and ensuring safe braking, especially in adverse weather conditions. Insufficient tread depth can lead to hydroplaning or reduced grip on the roads.

Additionally, checking tire pressure is essential to ensure optimal handling, fuel efficiency, and tire longevity. Under-inflated or over-inflated tires can lead to uneven tire wear, blowouts, or decreased fuel efficiency. Therefore, maintaining the correct tire pressure and depth is critical for the overall safety and efficiency of the vehicle during operation.
