I was looking on Yogi’s pictures and it showed his tire.
This one:
Try-all.
Can’t be. That’s wider then a 2.5" tire. It must be a prototype.
Maybe its just the wide rim makes the tire look big
What??? No, that’s a try-all.

Its the tire that comes on that unicycle.
Notice they have the same tread.
Tryall tire looks like this on that unicycle:http://www.unicycle.uk.com/shop/shopdisplayproduct.asp?catalogid=812.
The tread is different, and it looks like a wider tire.
I may well be wrong, but I don’t think I am. 
could be the monty 2.7 inch tire

It’s the try all tread pattern, definatly not the monty. Could be a prototype 19x2.7" tire
Hi there,
it is the normal 19 x 2,5 TryAll tire in every picture !
The Monty 29 x 2,7 inch tire comes with a different profile. http://www.einradladen.net/catalog/product_info.php?cPath=5&products_id=394&language=en

Definitely the normal try-all mod tire.
You’re right.
It’s the normal Try-All 2.5 tyre, on a Try-All rim. The Try-All rims are a bit wider than most others and so it looks wider.
From UDC:
DX32 is 40mm wide
KH 19" Freeride is 42.2mm wide
Try-All is 47mm wide
Plus Yogi always runs his tyres at super low pressures.
Since getting my Large Marge rim, my muni is extremely stable and can be ran at very low psi. So I reckon his wider rims must give a fair degree of extra stability too, especially as Yogi always seems really stable on all sorts of tiny wee platforms/ledges.

good lord 47mm. damn.
for some reason, when I read the title of this thread, I thought it said, what child is this, like the song. that was kinda weird. anyway, I think its the regular Try-All tire.
My bad. 
Yup, it’s the try-all.
What threw me off was that the tread looked like the endomorph tire. I thought it might be a 19" proto of along the same lines as the 26".
ok cool. where can i get one of these in the US
That wheel is messed.
I think that it is the fact that the photographer is using a wide angle lens close up to the unicycle, it is merely the lens distortion which makes it seem larger.
I’m wondering what is going on with the random, um, “things” down the side of the wheel… (picture is more explanatory) Could anyone enlighten m?
maby there spokes that have come out???
Ya they are, as my brother said:
“that wheel is messed up.”
