What issue is caused by the rolling action of pendant supports on the BAK-12 arresting system?

The rolling action of pendant supports on the BAK-12 arresting system leads to the issue of tire casing. As the pendants roll, they create friction and wear against the tire casing, which can result in damage or degradation of the tire's structure. This wear can compromise the safety and effectiveness of the arresting system, especially during high-speed landings, where the integrity of the tire is crucial for effective braking and control. Proper maintenance and monitoring of the tire casing's condition are therefore essential to ensure the functionality and reliability of the entire system.
