In vehicle systems, CTIS stands for which of the following?

• A. Central Tire Inlet System
• B. Central Tire Innovation System
• C. Central Tire Inflation System
• D. Cargo Tire Inspection System

Answer: (C)

The concept being tested is the ability to adjust a vehicle’s tire pressures from a single centralized system to optimize performance across different terrains. This is what a Central Tire Inflation System does: it lets the operator change tire pressure for all wheels from one location, rather than needing to adjust each tire individually. Lowering tire pressure increases the contact area with soft ground like mud or sand, improving traction and flotation, while raising pressure on hard surfaces reduces heat buildup, improves steering responsiveness, and lowers rolling resistance. This capability is especially valuable in heavy or military vehicles that encounter varied surfaces, helping prevent tire damage and maintain mobility. The other names don’t match the standard function: one implies an inlet mechanism, which isn’t how tire pressures are controlled; another implies innovation rather than a practical system; and the last suggests tire inspection rather than inflation.
