Bicycle Quarterly put forward the idea that higher presure tyres feel faster because they transmit more vibration. Normally we would feel that vibration increasing as we go faster.

However,even though they feel faster, they’re actually slower. That extra vibration is coming from vertical deflection that a more supple (lower presure) tyre would allow to stay as forward momentum.

Personally I keep “25mm” (GP4Ks always seem to measure closer to 27mm for me) somewhere between 70-80 psi but then I’m the sort of madman that thinks I can feel the difference with latex inner tubes.
