I recently lowered my muni (knobbly) tyre pressure to 20psi.
Correction: my tyre pressure was lowered for me by mister northcott
after he tried out my muni. Before it was about 35psi, complete
guesswork as I had no other riders to help me out. Since most of my
riding isn't that technical I wasn't keen to lower it for a while for
fear of added rolling resistance.
But if there is any increased resistance I barely notice it, in fact on
rough tracks it seems to take slightly less effort. The tyre is much
more easily persuaded to roll over roots and stones, plus I tend to get
smoothly bounded up and down instead of juddered. Not to mention it
take a lot less effort to hop up kerbs, as the tyre bounces.
The only bad thing was that for some reason riding down stairs took a
turn for the worse and I had to effectively re-learn it in order not to
UPD. I'm very puzzled why that is.
My (hardly used) 20" freestyle with a slick Maxxis Hookworm tyre I used
to run at about 45psi, but due to at least two pinch flats I now
inflate it to about 95psi.
One curious thing I know is that all beginners seem to learn with
smooth tyres, yet they are typically inflated to about half their
recommended pressure which increases rolling resistance.
Often when I lend my freestyle to a beginner rider, they seem to have
difficulty adjusting to the high pressure. Usually this is because they
are used to the low pressure on their own unicycles. I have no idea if
they would have an easier or harder time learning to ride if they used
a uni with a high pressure tyre from the start.
Yet I prefer very high pressure in slick tyres (which is what they are
designed for), since indoors and on the road rolling resistance is
virtually zero making for less effort.
Low pressure in slick tyres is something I find awful to ride on, even
though I am okay with riding a low pressure muni tyre even indoors and
on the road.
