Why are the tyres of the cars, trucks and bulldozers treaded?

Correct option is A

The correct answer is (a) To increase friction and to give a better grip to them on the road.
· The primary purpose of tread on tyres is to increase friction between the tyre and the road surface.
· Treads help in channeling water away from the tyre's contact patch with the road, reducing the risk of hydroplaning and improving grip on wet surfaces.
· By providing better grip, treads enhance the vehicle's stability, handling, and braking performance, particularly in adverse weather conditions such as rain or snow.
· The design of the tread pattern also plays a crucial role in optimizing traction, noise reduction, and tyre longevity.
Information Booster:
· The treads of the tyres are meant to add beauty to its design: While tyre design can have aesthetic considerations, the primary function of tread is practical rather than decorative.
· To decrease the friction: Decreasing friction would reduce the grip on the road, making the vehicle less stable and more prone to slipping, especially in wet or slippery conditions.
· To increase the speed of the vehicle: Treads are not designed to increase speed directly; their primary function is to enhance safety and performance by providing better grip.
