FAA Aviation Mechanic Airframe (AMA)Landing Gear SystemsEasy
A tire installed on a jet transport main landing gear has no inner tube and depends on an airtight seal between the tire bead and the wheel rim. This type of tire is classified as a
- Apneumatic overpressure tire
- Bbias-ply retreaded tire
- Ctubeless tire
- Dradial tube-type tire
Show answer & explanationAnswer & explanation
Correct answer: C. tubeless tire
Tubeless tires seal directly against the wheel rim without an inner tube, reducing weight and heat buildup while relying on a proper bead seat and rim condition for an airtight fit.
Why the other options are wrong
- A. 'Overpressure' is not a recognized tire classification.
- B. Bias-ply and retread describe construction/repair, not the tube configuration.
- D. Tube-type tires require an inner tube; this contradicts the scenario.
Tubeless Tire
An aircraft tire that seals air directly against the wheel rim without using an inner tube.
- Bead seats against rim to form airtight seal
- Lighter and runs cooler than tube-type tires
- Damaged bead or rim can cause leaks
Memory trick: Tubeless = trust the bead, not a tube
