Yes, it would be interesting to know wouldn't it? Although these tyres of mine and directional tyres are not strictly the same. Directional tyres have to point in the right direction and not necessarily differentiate between front and rear. Well, as I understand it anyway. Unless of course someone knows better?

Bi-directional is both way depending on front or rear.
