Hi all,
I tried this for probably 20 minutes with all the strength I can
muster. Basically trying to pull on a Deda Tre RS corsa folding
clincher 700 x 23c onto my HED Jet road rims. Folding tires are nice
but new ones are difficult to mount. I have never had so much
difficulty in the past with any tire than this one.
When it came in the box, it was nice and pancake flat and I wondered
how it'll ever attain the round shape. What I tried doing so far is to
get the tire on the rim without the tube and leaving it on there for
sometime to "stretch out". But the tube is going to be hard as hell
because I don't see any space for it to get in there anyway. Whats the
"pro" technique here, bleeding hands and skill or any less gory way
out?
B.D
The pro technique is to try massage the tire beads into the center of
the rim which is a little deeper. this should create a little bit of
slack that would allow to get the stuborn part of the tire into the
rim. Basically you insert one bead all the way in. Then you inser the
other bead until you cannot go any further. At this point, you should
go around the tire massaging the beads towards the center of the rim.
Go back to the stubborn area and you should have created enough slack
to get it into the rim.
If this does not work, there is a special tool that pinches the tire
and forces it into the rim. However, you can clamp the tire with some
plyers and force it into the rim too. However, using the described
technique, I have never failed to install the most stubborn tires into
rims. I can also get pretty much any tire out of the rim. Hope that th
helps,
Andres
Thanks Andres.
I got the first tube and tire in after half and hour. Rear wheel
coming up. Wow, what a waste of time. I wish I had more patience. I
guess after this first time, it should be okay.

Get some different tires. Chances are, they'll go on easier. If you
stay with this nightmarish combination you have now, you'll run out of
censored vocabulary long before you are able to fix a flat. You need to
be able to get them on and off with your hands alone.

:) I think I can manage. Don't take offense at the bad vocab. Some guy
posted something elsewhere here saying he'd like to kill bikers. That
ticked me off....
I won't give up easily with these tires. Boy, they're expensive
clinchers. I didn't buy them to look at them sitting in the closet.
Worse comes to worst, I'll probably heat it up with a hair dryer or
something :)

I meant that you may run out of variety in your cursing if you decide to stay with this combination because it won't be fun to deal with out on the side of the road when you get a flat. As someone pointed out, tires vary in tightness by manufacturer. You could find an easier tire to deal, though it would be a trial-and-error thing.
