I was interested to note in one of the cited references that the suggested tyre rotation patterns all involved swaps between right and left. There was then the note: "Of course, if your vehicle has different sizes of tires from front to back, or if your tires are directional, these may not work."
I had heard that with modern tubeless tyres (as opposed to the tubed tyres on my 1925 Rover!), you should not reverse the direction of rotation. That note implies that there are such things as "directional tyres", but I would have assumed that they would always be clearly marked, and hence that any tyres not so marked could and should be swapped left to right. Any comments?
