forget its position.
Clean the area around the hole with soap and water if you have it, let it dry,
then rough up the inner-tube with sandpaper before applying the glue (not too
much) to both the patch and the area around the hole. It is important to keep oil
and dirt away from the patch and the glue so keep your hands clean. Wait 4-5
minutes for the glue to get tacky before applying the patch to the inner-tube. Put
something soft like a paperback or a plastic sandal above and below the patch and
tube and give it a good beating with a spanner or large screwdriver to make sure
the seal is sound.
Before putting the inner tube back into the tyre, check inside the tyre for nails,
glass, bits of metal and exposed rivet spokes. Also make sure that the protective
rubber loop between the inner-tube and the rim is snugly in place.

Slip the inner-tube back into the tyre and fit the valve back through the hole in
the rim. Secure the valve with the lock nut and make sure it sticks out straight.
Make sure that the inner tube sits snugly inside the tyre.
Now comes the tricky part. When putting the side of the tyre that you had
peeled off back on to the rim, make sure that the opposite side of the tyre is
touching the opposite side of the rim – i.e. the tyre is sitting snugly in its proper,
normal position which it is when it is pumped up. A few hits around the
circumference of the tyre or a little massaging to the edges will do the trick. If the
other side of the tyre is not sitting snugly then the elasticity of the tyre is
significantly tightened making the whole process of levering the tyre back on with
the tyre removing tools almost impossible.
If you are having a real hard time getting the tyre back on then I guarantee that
it is because the other side of tyre is not in its right position. If it is in the wrong
position then all that metal wiring in the tyre will work against you instead of
stretching easily which it does when the tyre is in the right position. Therefore
make a special effort to hit and massage the tyre into position. Putting the tyre
back on is either easy or impossible.
