To safely ensure complete tire deflation, which component is first screwed onto the valve?

• A. Valve core
• B. Deflator cap
• C. Bead seat groove
• D. Tire iron

Answer: (B)

Threading the deflator cap onto the valve stem first is the proper starting step. The deflator cap is designed to mate with the valve and provide a controlled path for air to escape, enabling safe and complete deflation when the deflation tool is engaged. The valve core is the internal sealing component already inside the stem and isn’t the item you connect first in this process. The bead seat groove is part of the wheel where the tire bead sits and isn’t involved in deflation. The tire iron is used for mounting or removing tires, not for the deflation sequence.
