Well since no one wanted to do the research, I did.
I have in my hand a "Tire Maintenance Warranty and Safety Manual" from the
*Firestone Co.*.
On page no. 10 it states the following: The purpose of tire rotation is to
minimize irregular or uneven wear caused by maintaining a tire in one
rotation direction and one position over an extended period. The following
rotation patterns are normally recommended for *radial* passenger tires:
R.W.D
LF to RR and RF to LR, LR to LF and RR to RF
F.W.D.
LF to LR and RF to RR, LR to RF and RR to LF
Some exceptions to these patterns may exist. See your owner's manual for
recommended pattern. (in the case of this particular vehicle the owner's
manual indicates either the R.W.D procedure or the five wheel swap that I
posted originally.
Later folks. ;-)

From what I understand you should NEVER switch sides on a radial...
That's why Dodge doesn't show the spare in the rotation, because you
should keep left tires left and right tires right (i.e. keep direction
of rotation the same for the life of the tire). Since the spare
(hardly ever) never gets used, it hasn't a set direction.
The method the ferd manual used sounds like the old bias-ply
(non radial) method.
Thats what I think ... anyway.
