View Full Version : Help me, Please --- I can not change these dang tires!

Hello All,

After the latest bike theft, I got a nice hybrid and a couple of old bikes
to "play with".

One of the old bikes came from e-bay and was just US $41. It is a Fuji
Roubaix GPX from about 1991. The guy told me there were wheelset issues and
I have greased up the barings front and back.

BUT --- he sent damn racing tires, 3 sets of the stuff. Fancy colors and
700c x 23cm and I can not get the things on and off the rim without taking
a whole day. I broke one of my wheel tools !!

I hate to not use these real fancy "Wolber racing" rims, but I need to be
able to change a tire without using up all my vacation to do it.

Why is it so hard???

What should I do?

Ha! Good one.

I got a road bike from around 1980 and one from around 1990 to play with
myself. I refuse to let the LBS know I can not even change a dang tire!

Well, I have got it done one or twice, but I can not see me changing this
stuff out on the road.

Are you sure you're not mixing 27-inch tires and 700mm rims?

My very old 1980's (?) Nishiki road bike has 27" tires and they are very
easy to change.

My 1999 Cannondale H500 hybrid has 700c "street tires" that are also very
easy to work with.

I never have a flat with either one.

My Fuji 1991 road bike came with 700c racing rims and racing tires by
Michelin. They are 700x23c Axial Carbon High density. Damn pretty things
they are. I did get them on the thing a couple of times, but the rim tape
got all fouled up and I only got to do 3 or 4 blocks before a flat. I have
yet to complete one ride. I am just a flat making machine!

One of the tires ( I got 6 when I bought it) is a 700x25c that I can get on
and off a tad better than the 700x23c. I guess I'll throw all these pretty
racing tires away and get something I can work with, unless someone has an
idea on how normal folks can use these tires.


Oh, to answer your question --- the bike is 700c all right.

I have (or had, since I threw them away in disgust) a pair of cheap Alex
rims. I had to use screwdrivers to pry the tire onto the rim....obviously
it's diameter was just a tad too big. I thought all bike wheels would be
that way until I changed a tube on some Velocities, I didn't even need tire
tools for that one.

Is there a chance you have 27" rims and 700c tires? I remember my old
Raleigh race bikes having 27" rims. It wasn't until I got my team issue
professional that 700c tires were standard. I'm not sure but the 27" rims
are a bit bigger than 700c. The ISO designation for 27" rims is 630mm, its
622 for a 700c.

Thanks for the tips.

I had at it again today. Armed with better rim tape, the correct size tube,
and some baby powder --- I got the job done!

It is raining again here in Orlando or I would go see if I can get 3 blocks
from home on this bike without a flat. But, I do know I can get the tires
changed.

Glad to hear you got it going. I use Carbons and they're my new fave
tire.

Also try working the tire back and forth working from the valve stem
around to the opposite side. You want to try and work the tube away from
the bead so that it's seated dead center in the tire. This should make
it a little easier to push that last section of bead over the rim.

It seems to me that certain brands of tires matched with certain brands
of rims are tighter than others. I suspect that all 700c tires aren't
created equal.
