[quote=“nitroinsane,post:11,topic:38692"”] it does when ur running a very low profile tire which makes a really stiff sidewall which is not good for snow. [/quote] Please explain how cornering stiffness is going to effect traction over different surfaces, and why a lower cornering stiffness is preferred for low mu (traction surfaces such as snow, ice, mud, ect…) Assuming that he is running the same tire front and rear Cf!=Cr will be a moot point. CF and Cr are pretty much a non issue when compared to more important things such as allowing the tread button (tire) to rotate. Since it is the only way Fy can be generated for any tire in any condition period. It doesn’t matter if it is a full race slick on a dry track or a all season bouncing through mud puddles, if it is not rotating it can not create Fy (max). ---
