Figure no. 6 Tire C<strong>or</strong>ner<strong>in</strong>g Side F<strong>or</strong>ce as a Function of Slip Angle f<strong>or</strong> Some Race <strong>Tires</strong><br />

Street tires exhibit the same characteristics except with lower maximum values, a smaller<br />

rate of <strong>in</strong>crease from zero slip, and about twice as large of a slip angle at the maximum<br />

value. The maximum value compared to the tire load determ<strong>in</strong>es the maximum mu value,<br />

see figures no. 3 and 4.<br />

The rate of <strong>in</strong>crease (<strong>or</strong> slope) of the c<strong>or</strong>ner<strong>in</strong>g f<strong>or</strong>ce from zero slip is essentially the side<br />

f<strong>or</strong>ce at a slip angle of 1 degree and is called the c<strong>or</strong>ner<strong>in</strong>g f<strong>or</strong>ce coefficient Cf. Figures<br />

no. 7 and 8 show values of the c<strong>or</strong>ner<strong>in</strong>g f<strong>or</strong>ce coefficient f<strong>or</strong> typical street tires and the<br />

race tires of Figure no. 6 respectively.
