Tyre Rolling Radius
The effective radius of a tyre loaded against a surface.
R = rim size [inches]
W = tyre width
P = tyre profile
Example: for a tyre size of 245 35 R17 this gives a rolling radius = 295mm
Calculated Rolling Radius using above formula versus quoted Rolling Radius
The equation is for the best fit straight line through the data points, this
should be y=x to be a perfect fit.
