What happens to the tires if brakes are re-applied heavily after initial application?

When brakes are reapplied heavily after an initial application, one potential outcome is that the tires may blow out from being locked. This occurs because hard braking can cause the wheels to stop rotating while the vehicle is still in motion, leading to a situation known as "wheel lock." When this happens, the tires skid on the runway surface, generating excessive friction and heat. If the tires reach a critical temperature or if the pressure inside the tires is not sufficient to handle the stress, a blowout can occur.

Understanding the dynamics of tire response during heavy braking is crucial for maintaining safety and performance. Proper braking techniques involve modulating brake pressure to prevent wheel lock and maintain tire grip. This knowledge is important for pilots, as it helps them manage their braking strategies effectively during landing and taxiing phases.

Other options point to various effects of heavy braking, but the correct answer specifically addresses the critical risk of tire blowouts due to lock-up, highlighting the importance of controlling braking force to ensure tire integrity.
