how to tell what wether i got a front or a back Psycho K

[IRIX]

I found a NOS Amber walled Psycho-K kevlar bead tire in my LBS today, still in the box, folded and soft.
I was hoping it was a pair but alas, only one was in the box. The guy GAVE it to me.. It was just some old junk that came with the store when he bought it in 2006.

Now i just need another one, but how to tell if I have a rear or a front tire?
Says nothing on the box or the tire it self.

Point forward for front, point backwards for rear, one tyre did both....

Original Psycho were fr or rear fit iirc. There was a Psycho 2 which was a bit closer in tread pattern & not in a folding/Kevlar version iirc.

Both great tyres imo. I just got hold of a Nos Psycho K as it goes.

Nope all tioga psychos were unidirectional, I know as I had them on my C16r as the local shop sold a big ok batch at £5 a tyre - I curse not picking up £50 worth and stashing away...
