One tight tire!

Quoted message said:

there any tricks for getting a tight
fit on?

Get some really good tire levers. The chinese plastic ones will snap when
forced to the limit. Something in strong nylon would do the trick.

I have some DIY metal levers but even they bend(the handle for my
crescent wrench won't even fit).I've done a bit more research and it
looks like this is par for the course with wire beads.Funny though I
never used to have this problem with even the cheapest 27x! 1/4 tires.

Here's what you need:

What rim and tire do you have? Some rims like the Torelli Master are
murder, regardless of the tire. You can try using a thinner rim strip.
Also, when most of the tire is on, push the beads together on the part
that is already on, so that they rest on the deeper part of the rim.

It's a Meile rim and a Continental Ultra-Sport tire(a cheapy).

That looks good.Anyone know how to make a homemade version?

I advise against this strongly. Using tools to put the bead on a rim is
very likely to cause a pinch flat. I learned the hard way, many times.

Try to take all the air of the tube and massage the tire walls towards
the middle of the rim again. Push the tire wall with your thmbs to the
middle of the rim going around the entire rim. This should create
enough slack to force the tire in. Place the palms of both hands on top
of the part of the tire that is still outside. Close your hands aroud
the tire and rim. With a twisitng motion of the wrists, try to force
the tire in. If this still doesn't work, with the cresent wrench, clamp
the portion of the tire and tube that are still out of the rim. Use
the cresent wrench to force the rest of the tire in. Once you got it
in, check to make sure that the tube is not pinched between the tire
and the rim. Put a little air and massage the entire tire and tube to
make sure that it fits completely inside the tire. Put more air, and
check for buldges, meaning that the tube is pinched between the tire
and rim.

Thanks for all the feed back.I'll give it my best shot.

I've pinched perhaps one tube doing this and that was quite a long time
ago, so it's possible of course, you just need to be careful. Usually
using two levers is better than one, and good levers are rounded.

That said, I can usually mount tires with the heels of my hand with little
effort.

I've had the same problem with the same tyre and a Mavic rim.
I have heard about Continental having manufacturing problems
with their overseas factories, maybe that includes using correct
measurements within tolerance?

Use a clamping wrench.

I recently had to replace a tire on an old(Suntour freewheel)700c
wheel.I got the old one off OK but I could get the new one on for the
life of me.So I took it into a shop and the guy manaaged to install it
with a great deal of difficulty.It was only one day until I had another
flat and I couldn't get the darn tire off.Are there any tricks for
getting a tight fit on?What could be causing this?I know the tire
should be pinched to give it more slack but that was inadequate in this
case.

Some tires are slightly smaller in actual bead diameter than others.
This can make them a real pain to install. Some of the worst
offenders in my experience are brand new Kevlar-bead tires, which
often seem to be excessively tight on first installation, and then
become easier to work with after they've been inflated for a week or
so.

My policy is to not use a tire that doesn't fit properly; if I can't
get it on without tools, I doubt that I will be able to pach it by the
side of the road...and that's not an acceptable situation to me. Your
needs and preferences may vary.

Is the spoke tension @ 100 kgf?
Sometimes the rim will pull in enough when properly tensioned to make tire installation go from a "bear to a breeze".
A small amount of talc can also make the job easier.
As others have mentioned, some tires are on the minus side of the Bead Seat Diameter tolerance... and some rims are on the plus side.

What kind of rim strip? Thicker rim strips will make it tough to
install narrower and/or less flexible tires. In extreme cases,
replacing a conventional rim strip with fiberglass-reinforced strapping
tape is the only solution.
