Tyre spring rate

[willeng]

Could anybody help me out with a simple test method to find the Tyre Spring Rate or a Constant figure to use in suspension programs for the Tyre Spring Rate in Kg/cm or lb/in.

Thanks

Sure. It's easiest to do it at the back. Measure the rolling radius (ground to wheel centre) unladen. Put two passengers and some weights in the back. Measure it again. Measure the corner weights in the two conditions.

should be around 250 N/mm
