There are many ways to describe the factors contributing to the directional control dynamics of motor vehicles. The cornering compliance concept is particularly applicable to the tire intermix situation since it helps to separate the front and rear contributions to total vehicle performance. The relationship between cornering compliances and vehicle response properties, discussed in previous papers, is reviewed. The contribution of tire mechanical properties to cornering compliance is described. Typical compliance levels associated with intermix of generic tire types, wear states, and brands are listed.
