An apparatus should get tires every how many years?

• A. 7 years
• B. 5 years
• C. 10 years
• D. 3 years

Answer: (A)

Tires age over time even if the tread looks okay, because rubber hardens and cracks with heat, sun, and flexing. For an emergency apparatus, this aging can weaken the sidewalls and structure, raising the risk of a failure during high-stress driving. Because of that risk, the standard replacement interval is seven years, which helps ensure tires are in reliable condition for urgent responses. If you notice any cracking, bulges, cords showing, or other damage, replace sooner. While some departments may adjust schedules, waiting until ten years increases danger, and replacing around seven years is the safer, recommended practice.
