I have faith in Sheldon and Jobst's arguments about hydroplaning.
I do not understand the action of a wheel locking up (entering a skid), other than the intuitive level of braking ~> locks up / doesn't lock up.
I do not understand why the rear locks up more readily on wet asphalt.
Today my rear wheel locked up much more readily, and surprisingly sooner than I would have expected—given that I expected early locking up behaviour.
Why does the rear wheel more readily lock-up on wet asphalt than on dry asphalt.
I've already read this answer: What is the recommended type of tire for riding on wet pavement?
I'm running 47-559 marathon pluses, the bike & load is 20kg ish, I'm 110kg ish.
The ideal answer would give both the science, and render it in a form that a humanities cyclist like myself can comprehend even if by analogy.
