What three things can reduce traction?

Three things that can reduce traction are wet or slick surfaces, such as ice or rain, which diminish grip; worn-out tires that lack sufficient tread depth and fail to provide adequate contact with the road; and improper tire pressure, where either over-inflation or under-inflation can negatively affect the tire's contact patch and overall performance. These factors can significantly increase the risk of skidding or losing control of the vehicle.
