Not so much; it could be a little cushier, but since the Brompton has suspension in the back anyway, the effect of a cushier tyre is masked. It would be more forgiving than the Kojak wrt getting pinch flats which was the starting point of a week of trouble with the rear wheel.
I'm not convinced at all it is any major improvement and it is unlikely that I would buy another. The Primo Comet seems better for several reasons - it is narrower so would not pose any fitting problems, it is much more robust than the Kojak and is a fair bit lighter than the Scorcher, and is cheaper than both.
