Different rotational direction makes a difference. When you rotate side-to-side, the moved tire will rotate in a different dirrection than is did prior to the rotation.
If you have tire cupping happening on the front tires, then after rotation, they will rotate differently and so the cupping will be reversed and even out.
Sorta the same concept of why NASCAR drivers sometimes only change 2 (the outsides), since other than road courses they are always turning left (wearing the right side tires much faster). Applying that concept to MY driving, I make a LOT more right exits onto cloverleaf ramps (where I tend to not brake, just downshift) than left exits onto cloverleaf ramps. Rotating side to side will even out the wear extending the life of the entire set, otherwise I'd be going through left side tires a lot faster than rights.
While I don't pretend to be a NASCAR driver, I do sometimes try to impersonate one on the weekends (ask Ron H or T or REDCROSS about the "camper truck"), and I did drive by a Holiday Inn Express yesterday (oh yeah, I turned right as I was passing it
).
