This overestimates the ride natural frequency of the chassis, because it omits the tire deflection, which is about 0.37 inches assuming a tire rate of 2200 lb/in. Increasing static deflection to 2.88 in reduces the rear natural frequency to 1.84 Hz.

How did you calculate or approximate the tyre rate?

I had previously read that post and noticed that you mentioned a tyre rate of "approximately 2000 lb/in" but in the above quoted post you used "2200 lb/in" so I was wondering how you had come to use 2200 lbf/in rather than 2000 lbf/in? And from which table did you draw the 2200 lbf/in value from?
