Radials can also be rotated side-to-side, but it ain't easy.  You have to
take the tire off the rim, turn the *rim* around, and replace the assembly on
the car, making certain that the *old* forward direction *remains* the
forward direction.  Let me see if I can diagram this:

Rim 3   -                 -   Rim 4

        -------------------
            rear of car


Without changing the forward orientation of any of the tires, Tire 1 would be
mounted on Rim 2 or 4 and replaced on the *right* side of the car.  Tire 2
would be mounted on Rim 1 or 3 and replaced on the *left* side of the car.
And so on.  In this manner, the "set" of the tires is maintained while
allowing equal wear on the tire from side to side.
