Difficulty: EasyHydroplaning and Wet Road Traction Loss

Driving with under-inflated tires or severely worn tire treads significantly lowers the vehicle speed at which hydroplaning can occur on wet roads.

Answer: Answer

Answer

True. Worn treads or under-inflated tires significantly reduce a tire's ability to channel away water, lowering the speed threshold at which hydroplaning occurs.
Adequate tire tread depth and proper inflation are essential for pushing water out from under the tires. Worn treads or under-inflated tires impair water evacuation, causing the vehicle to hydroplane at significantly lower speeds than it would with healthy tires.

Step-by-Step Solution

1
Analyze how tire tread depth and inflation pressure affect water displacement on wet roads.
Deep tread grooves channel water away from under the tire. Low pressure or worn tread reduces the volume of water displaced.
Hydroplaning happens when water accumulates under the tire faster than it can be evacuated.
2
Evaluate the impact on vehicle speed threshold for hydroplaning.
Because less water is evacuated per second, a water wedge forms under the tires at lower driving speeds.
Vehicle traction loss occurs earlier when tire condition prevents proper water displacement.
