Wheels and Tires

Why do most aircraft tire manufacturers recommend that the tubes in newly installed tires be first inflated, fully deflated, and then re-inflated to the correct pressure?

• To allow the tube to position itself correctly inside the tire

• To eliminate all the air between the tube and the inside of the tire

• To test the entire assembly for leaks

The primary purpose for balancing aircraft wheel assemblies is to

• Distribute the aircraft weight properly

• Reduce excessive wear and turbulence

• Prevent heavy spots and reduce vibration

The removal, installation, and repair of landing gear tires by the holder of a private pilot certificate on an aircraft owned or operated is considered to be:

• A violation of the Federal Aviation Regulations

• Preventive maintenance

• A minor repair

Aircraft tire pressure should be checked

• As soon as possible after each flight

• At least once a week or more often

• Using only a push on stick-type gauge having 1-pound increments

If the extended longitudinal axis of the main landing gear wheel assemblies intersects aft of the aircraft, the wheels can be termed as having

• Toe out

• Toe in

• Negative camber

When a properly operating fusible plug has allowed a tire to deflate, the tire should be:

• Replaced

• Removed from the wheel and inspected for carcass and tread damage

• Externally inspected for damage

Chines are used on some aircraft nose wheel tires to

• Help reduce the possibility of hydroplaning

• Help nose gear extension at higher air speeds

• Help deflect water away from the fuselage

The fusible plugs installed in some aircraft wheels will

• Indicate tire tread separation

• Melt at a specified temperature

• Prevent over-inflation

What action, if any, should be taken when there is a difference of more than 5 pounds of air pressure in tires mounted as duals?

• Replace both tires

• Replace the tire with the lowest pressure
