Why do cars have treaded tyres?
To increase friction and grip on the road
Car tyres are treaded to increase friction and grip on the road, especially under wet or slippery conditions. The presence of tread patterns helps in channeling water away from the contact surface between the tyre and the road. This reduces the risk of hydroplaning, where the tyres lose contact with the road due to a layer of water. Therefore, by enhancing the frictional force, treaded tyres ensure better control and stability of the vehicle, contributing significantly to road safety. Hence, the correct choice is: To increase friction and grip on the road.
