Jan Heine's take on cycling is always interesting, and he's a pioneer in the push for wider is better, but he does suffer a bit of "religious tyre zeal"Here are a couple of links you may find interesting then Tangroup51 ; https://janheine.wordpress.com/2018/01/03/12-myths-in-cycling-1-wider-tires-are-slower/
and; https://www.compasscycle.com/product-category/components/tires/ You need the dollars though . . .
I've got the front wheel of the first set of wheels that a friend built me, probably around 1990, pinned as a plant trellis on the wall in our back garden. The tyre on it is a 700x20mm. I have vague recollections of inflating it to some eye-wateringly high pressure too! I guess the roads were much better then (ah, nostalgia) and, like the tyre I was considerably skinnier!
I think he's just making a general observationMaybe I am reading it wrong but the OP seems to think that it is tyre size affecting speed, acceleration and responsiveness. I would suggest that it is more likely the tyre type. GP4000 II are a performance race tyre, marathon greenguards are built for tanks.
