What is the most effective way of reducing hydroplaning?

• A. Increasing tire pressure
• B. Grooving
• C. Applying sealant
• D. Reducing speed

Answer: (B)

Hydroplaning happens when a layer of water builds between the tire and the runway, lifting the tire off the surface and breaking traction. The most effective remedy is to let water escape from under the tire, which is exactly what runway grooving does. The grooves provide drain channels that quickly remove water from the contact patch, thinning the water film and allowing the tire to maintain contact with the pavement. With better drainage, friction is preserved and the risk of hydroplaning is reduced across a range of speeds and water depths. Increasing tire pressure changes the size of the contact patch but doesn’t actively remove water, so it’s less effective as a hydroplaning preventive. Sealant doesn’t address water evacuation either, and reducing speed, while helpful, isn’t always practical or sufficient in busy conditions. Grooving directly tackles the water layer, making it the strongest preventive measure.
