There was a theory at the time that, depending on the bike's steering geometry and front/rear weight bias, having a treaded tyre like a TT100 on the front wheel could induce front-end shimmy that could lead to a proper wobble.
For some bikes (I remember the SOHC Honda 750 being one), a ribbed front tyre was recommended to avoid this.
