With respect to tire rotating, I have been told recently, by more than one tire shop, that the old warning about rotating radial tires; that is only go front to back, never cross, is no longer valid, and many tire manufacturers now recommend rotating as follows (for a rear drive car):

Drive wheels straight forward, non-drive wheels cross, and back (e.g. right rear goes to right front, right front goes to left rear, left rear goes to left front, left front goes to right rear.)

Anyone else heard of this, or doing this?
