What on a tire is designed to deflect water away from engine intakes?

• A. Chine
• B. Tread groove
• C. Bead
• D. Valve stem

Answer: (A)

Chine is the feature that deflects water away from engine intakes. It’s a small ridge or deflector on the tire that channels water to the side as the tire spins on wet surfaces, helping prevent water from being sprayed into the engine intake during takeoff or taxi. Tread grooves mainly handle water to improve traction and reduce hydroplaning under the tire, not specifically to protect engine intakes. Bead is the part of the tire that sits on the wheel rim, and the valve stem is simply for inflating the tire.
