Compute wheel radius

[cologne]

How can i compute the wheel radius?

Code:

size = 355/46r13

Code:

radius = 355 / 0.46 + (13 * 2.54) / 2 ;

Correct?

[NaN]

Radius in meters (cardynamics.cpp line 357):

Code:

radius = section_width * 0.001 * aspect_ratio * 0.01 + rim_diameter * 0.0254 * 0.5;

Code:

radius = section_width * 0.001 * aspect_ratio * 0.01 + rim_diameter * 0.0254 * 0.5;

Why these factors: 0.001 and 0.01?

[NaN]

aspect_ratio is in %, section width in mm

Thank you! I forgot to think! ;-)
