I experimented quite a bit to arrive at my favourite PSI split for these tyres and in that process heightened my road feel senses simply through paying repeated attention to slight differences. That said, there will no doubt be more experienced and sensitive riders out there that may pick up these material differences, which are objectively significant when comparing both in hand, through the tyre, but I personally cannot despite keeping PSI exactly the same (overinflate a bit then drop to exact pressure with a Topeak air release gauge) on very familiar and varied road surfaces. So to me at least, 5 PSI up or down make a far greater difference in comfort/smoothness/perceived rolling resistance than these two Pirelli tube types.
