What years do these tyres cover? Tioga Psycho 2

Want to put these to use on the right era bike.
Thanks

Psychos appeared on John Tomacs bikes mid 92 but werent in our shops in the UK until early 93. They were pretty common through to 97ish until Tioga released the Psycho TT & Edge models.

Great info - many thanks! Does that cover the II version?

I haven't manged to find a decent set of Psycho's yet, they really don't fare well to age. All mine have serious crispy sidewalls and as for the rubber, its more like crumbly foam :s. Whilst we are on the topic, unless i'm mistaken there seems to be very little covered about what tyres relate to what years? I've got IRC Mythos on some of my late 90s builds and they seem to have survived well over 20 years
