Hi, Spitters.

There is one other factor that enters into the formula (Formula :) --
resonance.  The rack/pinion/tierods/steering column/steering
wheel/tires/wheels/what-have-you are not perfectly rigid, but have
distributed masses and spring rates which can resonate, provided the
correct input frequencies.  Larger steering wheels form a flywheel at
the top of the steering column that can shake like bu**ery if the
vehicle speed is right.  Smaller steering wheels, with lightening
holes in the spokes, provide a higher-frequency system (which is
easier to control and less fatiguing to operate.)  Ditto lighter
wheels and tires, which also contribute to better sprung/unsprung
weight ratio and reduced rotating inertia.  i.e. faster linear
acceleration.
