I would agree with that OS, for the very first time I noticed just yesterday when I had two new Metzlers fitted to my TB that upon leaving the tyre shop I felt if I was riding on ice, the feeling didn't leave even when I got home about 40km away. I've never experienced that before and I'm using exactly the same type of tyres that were replaced.
It was a really odd feeling that I even thought that the pressures were wrong, however, as yet I haven't yet checked them but will do so before I ride it again.
I also had to get a new front one for my CB today, needed to pass the WOF, (Govt test) and that had a perfect feel (Michelin Pilot Road). If anything I should have experienced some difference as my rear tyre, same make has only about another 2000km left on it. (Yes I know you should change them as a pair but they are bloody expensive and my rear tyres wear faster than the front.)

Ride on !
