What are the best safeguards against heat buildup in aircraft tires?

The best safeguards against heat buildup in aircraft tires relate to operational practices that minimize stress on the tires during ground operations. Short ground rolls limit the time tires spend in contact with the runway, thereby reducing heat generated from friction. Maintaining slow taxi speeds contributes to this by ensuring that tires do not experience excessive wear and overheating. Minimum braking is important because heavy braking increases the temperature of the tires due to the friction generated, which can lead to overheating. Lastly, proper tire inflation is critical, as tires that are underinflated can generate more heat due to increased flexing, while overinflated tires can result in uneven wear. Together, these practices create a comprehensive strategy for managing tire temperature effectively.

Other options, while they may provide some benefit, do not address the immediate operational factors that contribute to heat buildup as effectively. Continuous tire monitoring and frequent rotations are helpful but are more focused on maintenance rather than operational safeguards. Frequent tire pressure checks and load balancing are important for safety and performance but do not exert the same level of control over heat buildup during ground handling. Using high-temperature rated tires is valuable in specific scenarios but does not mitigate the risks associated with poor operational practices. Therefore, the first option stands out as it encompasses proactive measures to limit heat generation during
