a two part rubber such as this?

Wow that looks perfect. I didn't know you could get rubbers that would
vulcanize at room temperature. And it is not that expensive. I will just
have to figure out how to get it into Canada (anyone in Mane want to
lend me their address?)

This is about making tubulars (to be sewn up and glued to a rim), not
clinchers (with beads and a seperate tube).

this is not exactly what you're planning on doing, i know, but i think
it might be helpful. particularly that part about laying the cords and
binding them together (with latex). it doesn't say much about the tread,
though, but it at least seems that for a lightweight road tire, you
don't really need high pressure molds or anything.

to be frank, this is an extremely ambitious project, but i would really
like to see you do it. good luck!

No, man, I meant "hardcore" for wanting to build yer own tire. Leaves
those people building frames in the dust. We all assume the uni mantra
is "Ride, Fix, Ride, Fix, Repeat."

I've seen a lotta really amazing things in here. That'd be another one.
Think of the story. "There I was, down and flat halfway between Regina
and Swift Current. Lookin' around in the ditch I found the tread off a
semi tire, a ball of tangled fishing line, a pack of matches and a
half-full jar of Gorilla Glue..."

Seriously, I'm impressed.

naw man I would never ride that far south. Too flat and boring, besides
they have no trees and don't like hitch hikers. Up north is more my
style.

I started work on my 26" test tire. Using a 24" tire and tube to
simulate the 29er parts for the 32" tire.

I peeled the tread off the casing on the tire. I started off trying to
'skin' the tire like you would a deer but the casing really wasn't very
cut resistant and I only had about 1mm of leeway before cutting through
the tread. Basically I had painfully slow progress for the first 5 or so
cm and I think that all the old traders back home would deny knowing me
if they saw my attempt to skin the tire.

I got a bit wiser and started pulling threads with my pliers. Then I
realized that I could just peel the tread off the casing if done in the
right direction and having the sidewall cut down to but not through the
casing.

I learnt a bit about the tire construction through the deconstruction
process. There is zero stitching in the casing, even where the ends join
to make a loop. I think I am going to follow their example and trust the
glue/rubber to hold everything together.

I could not find any nylon fabric or RTV butyl rubber so I ended up
getting polyester and contact cement instead. what the hey, it is more
of a test on concept than materials anyway.

I was going to prep the material and make the casing yesterday but it
started to sleet. Sleet turned to snow and now rain. Once it dries up I
will give it a try. My biggest concern at the moment is that the tread
from the 24" tire is not as stretchy as I thought it would be. Maybe a
lighter weight donor tire would work better.

I thought of this thread whan I saw this bit on monocycles recently. If
you look closely at Ben Wilson's cycle, you can see a Schwalbe Marathon
sidewall logo. . . so is this some photoshop bit of hijinx?? or is there
really a schwalbe 48"?? tire out there??
Maybe unicyclists aren't the first to crack the "making one big tire
out of two smaller ones" construction DNA??

looks like two tires joined. It looks to me like there is a join near
where his hands are in the pic. There is also two logos on the side. I
wonder what he did with the bead and if he can feel the connections when
he rides on smooth surfaces.
