It was no more my intention to be snotty than it was probably your intention
to call the kettle black. The somebody confused could just as easily be me
as anybody else.
Using my equation:
tire diameter 25.6"
total toe measurement 3/8" ---> 3/16" per side
angle = arcsin [(0.5*0.375) / 25.6]
angle = 0.420 degrees
Using your equation with the units above:
Diameter * pi * toe in degrees/ 360
[25.6 * 3.142 * 0.42] / 360 = 0.094 or approx. 3/32"
Where did I go wrong? The reason I don't understand your equation is because
[(diameter) * (pi)] = circumference
and I don't understand what the tire circumference has to do with calculating
a toe measurement. It looks to me that this equation is calculating the
partial angular measurement of a treadface circumference.
[partial angle / 360] * circumference = partial circumference measurement for
a given angle
