Final answer:
Choose tires with better traction on snowy or icy roads to increase friction and improve control. More friction is also desirable during braking to ensure effective deceleration.
Step-by-step explanation:
When driving on a slippery surface with snow or ice, it is best to choose tires that create more friction with the road.
Winter tires, for example, have a tread pattern designed to grip the road better in snowy and icy conditions, thus increasing friction and improving traction.
Another example where more friction is desirable is during braking. When you step on the brakes of a car, the brake pads apply friction to the rotors, which helps to slow down the car. Without sufficient friction, the car would not be able to decelerate effectively.
