vertical stiffness coefficient of a truck tire 1

[zoghi]

Hello every body
I'm handling a suspension optimization and I need the vertical stiffness coefficient of a truck tire (for simulating it's equal spring stiffness "Kt&quot. Please help me to find it out some pieces of information about those values

I suggest you ask the tyre manufacturer. If all else fails they should be able to give you a chart showing rolling radius vs load vs air pressure which you can use to get an approximate siffness value. Cheers

Hello. I don't have any measurement at hand; if it can be of any help to you, truck and bus tires have generally a radial spring constant of 90 to 120 kg/mm.
