What helps most to prevent hydroplaning?

  1. Tires with a high air pressure only
  2. Good tires with deep treads
  3. Wide, smooth tires
  4. A heavy load in the trunk
Show answer

Correct answer: Good tires with deep treads

Deep treads let water escape from under the tires. Water deeper than the tread can still cause full hydroplaning.
