I agree. So does BMW.
Even for same size unidirectional tires on all four corners.

According to BMW, the only time tire rotation makes sense on a
rear-wheel-drive performance vehicle is if you do it yourself every 3000 miles
(before any wear becomes too great to affect handling).

On rear-wheel-drive performance automobiles, once you pass the 3000 mile mark,
you start noticeably wearing the rears in the center and the fronts on the
side. At this 3000-mile point-of-no-return, adverse handling will occur if you
rotate.

If you do rotate within the 3000 mile limit, make sure you readjust the
pressure differential between the rears and the front or you'll have other
handling problems you didn't bargain for.

Also, if you do rotate, use any pattern you like (crossing sides at random,
using the fifth tire, changing rotation direction, etc). Studies have shown
that none of these rotation patterns adversly affect anything and none are any
better than any other rotation pattern. Again, if you pass the 3000 mile point
of no return, stop rotating for the life of those tires (should get you at
least 30,000 miles depending on how aggressively you drive).

If you have a front-wheel-drive econobox (all fwd cars are compromises for
the sake of costs), things might be different though I've no experience with
low-performance fwd cars.
