a Bike Tire and Tube
have changed hundreds of tubes over the years and not
until my daughter asked me to show her how it's done,
did I realize that it wasn't as easy as it seems.
if its not already flat
Use the "tire levers" to pry the bead off
the rim and apply the second lever about two inches
beside the first
Most of the time you should be able to slide the first
lever across the rim to pop out one side of the tire
but if the tire is still too tight try pinching the
tire and tube together all around the opposite end.
This will loosen up the area you are trying to pry
off. Also only try to remove one side
of the tire bead at a time (pic
Once you have loosened off one side of the bead of
the tire, the other can be pulled off by hand.
carefully check the tire by running your fingers on
the inside of the tire all the way around. Most likely
you will find glass, thorns or metal fragments.If
they are not removed and you put a new tube in you
will need another tube with in minutes and you will
not be happy.
your new tube until it's a little smaller than your
tire and shove it into the tire. This will keep the
tube from getting all mucky and being accidentally
stepped on, and will hold the shape of your tire since
many tires are foldable and tend to want to roll up
and twist while your are trying to work with them.
most tires have a specific direction. If there is
no arrow on the sidewall showing you which way is
forward look down at the tread pathern.If the tread
has a Chevron or "V" shape to it, always
point the "V" like it's cutting the wind.
applies to both front and rear. Running the "v"
backwards will cause the tire to slide too easily
when cornering hard.
Put the valve through the valve hole in the rim.Then,
put ONE side of the bead on, by hand, then push the
tire back so the tube and tire are over top of the
rim .This is the time to check if the valve is sitting
straight down in the rim before you work the other
side of the tire bead.
the other bead on. This is done by hand, and is sometimes
very tight. By pinching the opposite areas, already
on the rim, you can give yourself a bit of slack to
pop the last bit of bead over the rim. If you start
to get frustrated because it's too tight and your
thumbs are aching from the strain, don't go for the
tire levers, or you will most likely pinch the tube
and you won't be happy. If you must use "the
levers" try sliding one inside, to push the tube
back out of the way,then prying the levers up and
over. This sometimes will work .....maybe.
