How often does the CTIS system adjust pressure?

The CTIS (Central Tire Inflation System) is critical for maintaining optimal tire pressure based on the terrain and driving conditions. This system automatically adjusts tire pressure to enhance vehicle performance, safety, and tire longevity. The frequency of adjustments helps ensure that the vehicle can adapt to different conditions effectively, providing the necessary traction and stability.

The correct choice indicates that the CTIS system adjusts pressure every 15 minutes. This timing allows the system to keep up with changes in load, speed, and terrain, ensuring that the tires remain at an ideal pressure for the conditions the vehicle is facing. Frequent adjustments can also help prevent tire issues, such as blowouts or excessive wear, which could lead to downtime or require repairs.

In comparison, options suggesting longer intervals for adjustments, such as every 20 or 30 minutes, would result in delayed responses to changing conditions, potentially compromising vehicle handling and safety. Similarly, an interval as short as every 10 minutes might be unnecessary and could lead to excessive wear on the system itself. Thus, a 15-minute adjustment interval provides a balance between responsiveness and efficiency in maintaining optimal tire performance.
