Definition of Problems in Tire Skid and Traction

Skid resistance on wet slippery roads is the dominant factor in safety problems relating to skid and traction. Although many testing and design problems exist, the basic question is how to determine when a tire improvement has been made which is critical to the safe driving of the majority of drivers. Understanding circumstances under which skidding accidents occur and defining the nature of the road surface are essential for the development of improved tires.
