What can happen if an aircraft tire flexes beyond design limits?

Improved shock absorption upon landing

Decreased tire pressure

Enhanced tire durability

Excessive heat build-up weakening the carcass construction (correct)

Why must vent holes in the lower outer sidewall of tires be kept unobstructed?

To release seepage of inflation gas trapped in the plies (correct)

To prevent tire flexing

To absorb shock better upon landing

To increase tire durability

What is the purpose of seepage holes in tube-type tires?

To strengthen the tire carcass

To allow air trapped between the tube and the tire to escape (correct)

To increase tire flexibility

To enhance tire grip on the runway
