The Central Tire Inflation System (CTIS) is designed to optimize tire pressure depending on operating conditions and terrain. It is crucial for maintaining proper traction, stability, and performance of the vehicle, especially in varying environments. The system stops operating when tire pressure drops to a predetermined low threshold, at which point it prevents further adjustments to protect the tires from undue strain. In this case, the system stops at 85 psi, because at this pressure, the tires are at risk of being over-inflated or damaged if any further inflation is attempted. Resuming operation at 115 psi allows the system to ensure a safe and optimal tire pressure level, enabling the vehicle to handle rough terrains effectively while maintaining efficiency and safety.

The specific values of 85 psi for stopping and 115 psi for resuming are essential figures that reflect the operational design of the CTIS in the MTVR, ensuring the vehicle remains functional and reliable under various conditions. This is a critical element for military and tactical operations where vehicle performance can significantly impact mission success.
