Why do tires have tread patterns?

Answer: Channels water to prevent sliding

Channels water to prevent sliding ✓ — Correct! Tread patterns have grooves that channel water away from between the tire and road. Without tread, water creates a thin layer that causes hydroplaning (tire loses contact with road). Tread maintains grip by pushing water aside through the grooves.

Reduces road noise when driving — Wrong. Tread can affect noise, but its primary purpose is safety—preventing hydroplaning by channeling water away from the contact patch.

Increases speed and acceleration — Wrong. Smooth tires actually provide better grip on dry surfaces. Tread exists mainly to channel water on wet roads for safety.
