At what temperature range do rubber tires typically ignite?

• A. 200 to 400 degrees F
• B. 300 to 500 degrees F
• C. 500 to 600 degrees F
• D. 600 to 800 degrees F

Answer: (C)

Rubber tires can typically ignite at temperatures ranging from 500 to 600 degrees Fahrenheit. This is critical knowledge for aviation safety, especially in environments where tires are subject to extreme heat due to friction, wear, or exposure to flames. Understanding the ignition temperature helps personnel recognize safe operating limits and the risks associated with tire fires. Being aware of the combustion threshold of materials such as rubber ensures that proper precautions can be taken during maintenance, inspection, and operations where heating might occur. This knowledge is vital for mitigating fire hazards and protecting both personnel and equipment from potential accidents.
