Question

Difficulty: EasyWet Weather and Aquaplaning

Tyre tread grooves are designed to channel standing water away from beneath the tyre to maintain contact with the road surface in wet weather.

Answer: Answer

Answer

True
The statement is true because tyre tread grooves are specifically engineered to disperse surface water away from the tyre's contact patch, ensuring the vehicle maintains grip and does not aquaplane.

Step-by-Step Solution

1
Identify the primary purpose of tyre tread patterns when driving on wet roads.
Tread grooves act as drainage channels that pump and direct surface water away from the contact patch.
Water must be evacuated quickly so that the rubber can maintain physical grip on the road surface.
2
Evaluate how this mechanism prevents the vehicle from aquaplaning.
Effective water dispersal prevents a layer or wedge of water from building up under the tyre.
Aquaplaning occurs when water cannot escape fast enough, causing the tyre to lose contact and ride on a cushion of water.
3
Determine the accuracy of the statement.
The statement correctly describes the design and function of tyre tread grooves in wet conditions.
Maintaining road contact through effective water channelling is the core design objective of road tyres in the wet.
