Well, I have 950 miles on my Coker this summer. The tire was getting
really worn, the first 250 miles wore quite quickly as I was not nearly
as good freemounting. Anyway, I was hesitant about changing the tire as
I had read of the difficulty many people had.
Here is how it went.
I removed the old tire. I have a cheap set of steel tire levers. I had
to use two of the tire levers to get the first part of the tire off the
rim. After that it was just my hands.
Then what we have all been waiting for. I put one bead over the rim,
hands alone, no problem. Prior to this I had put baby powder on the
inside of the tire and on the tube. Then I inserted the tube in the
tire. Just enough air to keep it from folding. Then I started to put
the second bead on only using my hands. I got to a point where I had
about 12 inches of the bead still to put on, and my hands could not do
it. I enlisted a helper, a 15 year old daughter. On the side of the
rim opposite where I was trying to install the bead, I had her hold the
tire, pushing the bead towards the center of the rim. Mind you she is
only 15 and really had no interest in doing anything with my unicycle,
but I had interrupted here internet time and she knew she could not
leave until I had finished my adventure.
I then was able to do another 2 inches. I was getting worried here. I
then grabbed my tire levers. I used one to pull another inch over, and
a second to pull one more inch over. Then I removed the first, and I
was able to pull the rest on with my hands. It was done. I pumped it,
and two days later it still holds air, so I did not puncture the tube
either.
It really was not that bad. I could not believe what I had read.
People taking it to bike shops and the shops claiming it was impossible.
Mind you I have been biking for 15 years and have changed many tires,
but never a Coker.
The only issue I had was trying to seat the bead when it was pumped up.
I had to use two tiny squirts of wd40 on the bead, then it just slipped
into place.
Anyone can do this. It took me about 40 minutes, going slow and
cautious.
