Why to use this formula?
With the tyre selected able to generate our required cornering forces, we can add in our tyre vertical spring rate to come to a wheel centre rate. In reality, there are two springs acting between the chassis and the ground. These two springs are the wheel centre rate, controlled by the spring and anti-roll bar, and the vertical tyre rate, controlled by the tyre compound, sidewall stiffness and operating pressure. In order to combine these two spring effects to create one, we must add them together. Although they are acting in series, the equation is slightly different than our linear springs in series equation due to the tyre rate being involved. Therefore, we use this formula.
How to Calculate Tyre Vertical Rate given Wheel Centre Rate?
Tyre Vertical Rate given Wheel Centre Rate calculator uses Tyre Vertical Rate = (Wheel Centre Rate*Ride Rate)/(Wheel Centre Rate-Ride Rate) to calculate the Tyre Vertical Rate, The Tyre vertical rate given wheel centre rate formula is used to find the spring rate controlled by the tyre compound, sidewall stiffness and operating pressure of the tyre. Tyre Vertical Rate is denoted by Kt symbol.
