I am in charge of designing the Aero for my FSAE team in UAE.I am doing it for the first time and I have a doubt.Firstly according to me,the tire can perform best only at a particular peak normal load.After that the performance of the tire will go down.So ,I want to limit my downforce accordingly.Is the thinking correct?
Secondly I am referring to TTC data for my Hoosier R25B 20.5 x 7 x 13 tires in OptimumT to confirm the above theory.However my graph of lateral force vs normal load is linear.Even the graph of lateral friction coeff with normal load is a straight line.
So I am wondering if I am thinking along the wrong lines or I have done analysis of tire data wrong in Optimum K.
