Which statement about tire tread is correct?

• A. Increase tire wear.
• B. Improve steering response at high speeds.
• C. Will help to reduce the likelihood of hydroplaning.
• D. Increase fuel efficiency.

Answer: (C)

On wet roads, hydroplaning happens when a thin layer of water builds between the tire and the road, causing a loss of traction. Tread grooves act like channels that push water out from beneath the tire, helping the tire maintain grip with the road surface. That’s why tire tread helping to reduce the likelihood of hydroplaning is the correct idea. Tire tread isn’t about increasing wear, and worn tread actually makes hydroplaning more likely because there’s less water-shedding capability. It also isn’t a primary driver of steering response at high speeds—handling comes from overall tire performance and vehicle dynamics, not tread alone. And tread depth isn’t a direct way to boost fuel efficiency; while some tires with low rolling resistance can improve economy, tread pattern itself isn’t the main factor for fuel use.
