WebCornering Stiffness. A fundamental measure of the grip capability of a tyre in the lateral sense is known as the cornering stiffness. This is expressed as the force generated per degree of slip angle (N/ °).For a given slip angle, a tyre with a higher cornering stiffness will produce a greater lateral acceleration and this is a key performance measure of any tyre.
