20mm 700c tyre, 130 psi. Great fun to ride while it stays at 130 psi.
Today, for about the fourth time in about six rides on fairly simple terrain, a puncture and a long walk back to the car.
I can’t have an impractical unicycle; that would be silly.
Looks like I’ll be going back up to a massive 23mm, or possibly even (gasp!) a 28mm.
The Show Off Shown Up
Out onthe 700c, pootling around the main lake at the Water Sports Centre. There is an event on, with Scouts and Guides dotted about the place in small groups.
As part of my usual circuit, I ride down a short ramp onto one of the pontoons, and along the pontoon, intending to turn up the next ramp back onto the main path.
A group of about six Scouts is passing.
The biggest says, “Show off!” in a scornful tone.
A smaller one says, “That’s way cool. How long did it take to learn that?”
They all turn to watch me, and, under the gaze of so many eyes, I decide not to essay the tricky little step at the bottom of the ramp, and I dismount.
Then, on a mischievous whim:
“OK, so which of you just shouted, ‘Show off’?”
Five small Scouts point to one larger Scout.
“OK, who’s the show off? The person quietly practising his sport, or the person making uncalled for remarks to a stranger just to impress his friends?”
“Er… but you rode onto the pontoon and I thought…”
“I was riding my unicycle. I didn’t ask you to comment. There was no need to comment.”
“And then he said…” Large Scout - conspicuously failing to have courage in all difficulties - points to smaller Scout accusingly." This makes him Fair Game.
“Oh, they all think you said it. Shall we have a vote?”
“Er…”
“Are you a Scout?”
“Yes.”
“Well I was once, and if you behave like that and shout daft comments at strangers you’re a disgrace to your uniform.”
“Er…” (mumbles) “Sorry.”
“Now, which one of you asked the sensible question?”
Small Scout with big grin: “That was me.”
A few minutes later we parted as friends. Two minutes after that: a puncture and a long walk.
I’m eager to hear your description of a practical unicycle. That is, practical for uses other than scraping shins and amusing pedestrians.
That’s what they teach in clown school, I hear.
maestro, one step towards a practical unicycle is a ridable one 
Thank you for confirming my suspicions about unicycling on super-skinny tires. 
I used to use skinny wheels on my track unicycles, but usually just down to 1.25" or so, and then mostly on the track. I’m sure yours would last longer in a controlled environment as well.
I wish we could have a skinnier rim/tire on a 36" wheel. Even if it was not that skinny, it would be so much lighter I’m sure it would be really nice to ride!
Even if it’s not “waffer thin”…
Bummer. Whoever sold you that 20mm cross-country tyre may have been a little dishonest
