What should be done if a tire is found to be under-inflated during a pre-trip inspection?

If a tire is found to be under-inflated during a pre-trip inspection, it is essential to inflate it to the proper pressure before proceeding. Proper tire inflation is critical for vehicle safety, handling, and fuel efficiency. Under-inflated tires can lead to poor traction, increased tire wear, and the risk of a blowout, which poses a serious hazard on the road.

Before taking a commercial vehicle out, ensuring that all tires are inflated to the manufacturer-recommended pressure is a fundamental safety measure. It helps maintain uniform tire wear and optimal contact with the road, contributing to safer driving conditions and better performance.

The other options do not address the immediate need to rectify the situation; ignoring the issue, measuring pressure after driving, or only checking after the trip does not mitigate the risks associated with driving on under-inflated tires. Taking preventive action is critical for the safety of the driver, passengers, and other road users.
