In addition to checking for tread wear on tires, it is crucial to inspect for visible damage to the tire. This includes any signs of cuts, punctures, cracks, or bulges, which could compromise the tire's integrity and lead to failure while on the road. Damaged tires are more susceptible to blowouts and can significantly impact the safety of the vehicle, especially for commercial drivers who may be carrying heavy loads.

While tread wear is important for maintaining traction, an undetected injury to the tire can pose a greater immediate risk. Therefore, conducting a thorough visual inspection to identify any physical damage ensures that the tires are safe and reliable for driving.

Other options, such as checking the color of the tires, focusing solely on air pressure, or determining the type of tire tread, may not provide critical insights into the immediate safety and performance of the tires as visible damage does.
