What is the primary purpose of a Central Tire Inflation System on a military vehicle?

• A. To automatically adjust vehicle height
• B. To adjust tire pressure for traction and fuel efficiency
• C. To inflate tires only during parking
• D. To monitor tire tread wear

Answer: (B)

The function being tested is the ability to tailor tire pressure to the terrain and driving needs to keep the vehicle mobile and efficient. A Central Tire Inflation System lets you adjust each tire’s pressure from the cab, so you can lower pressure on soft ground to increase the tire’s footprint for better traction and flotation, and raise pressure on hard surfaces to reduce rolling resistance for improved fuel efficiency and stability. This adaptability is essential for military vehicles that must traverse a mix of sand, mud, snow, and hard ground while carrying loads.

It isn’t about changing vehicle height, it isn’t limited to inflating tires only when parked, and it isn’t a system for monitoring tire tread wear.
