What is an acceptable condition for tires as per the pre-trip inspection?

Having both the inside and outside sidewalls intact is crucial for tire safety and performance during a pre-trip inspection. Tires must be free of any visible damage, such as cuts, bulges, or severe tread separation, which can compromise their structural integrity and lead to failures while driving. Ensuring that the sidewalls are intact means that the tires are capable of maintaining proper air pressure and will function effectively under normal operating conditions.

The presence of severe tread separation and excessive wear indicates that the tires are no longer in a safe condition for use, as they may lead to blowouts or loss of traction. Similarly, cuts or bulges on the tire can suggest that there is damage that could result in failure. Hence, checking for intact sidewalls is a key aspect of ensuring overall tire safety during inspections.
