Type ___ extra-high pressure tires are the standard for jet aircraft.

• A. 5
• B. 7
• C. 9
• D. 11

Answer: (B)

Jet aircraft require tires that stay very stable under high landing speeds and heavy loads, so the tire design uses higher inflation pressure and a stiff construction. Type seven extra-high pressure tires are built to meet those needs, providing a small, well-supported contact patch that resists excessive deformation and heat buildup during touchdown, roll, and braking. This makes them the reliable default for most main landing gear on jet airliners. Other tire types exist for different aircraft sizes and missions, which means they’re not used as the standard on jets.
