Default Flat repair

I had to repair a flat. Have some questions.

Is it best to apply patch to a completly flat tube?

I found a small copper wire in tire.

Is there something to minimize what can puncture tire?

Thanks

If you find a way to escape flat tires do write back.

One way is to not ride. :-)

Where does the stitching come in ?

My rim has a narrow piece of rubber in the inside.
Guess it protects from the spokes.

I will strongly suggest you sand your tubes. Sanding not only cleans
the surface, it roughens the surface and increases the area that glue
and cushion gum on the patch have to bond to. Done right, there's a
30 or 40% increase in tensile strength of the patch.

Foam rubber!

I found Mr.Tuffy liners to be quite good. Stay away from cheap thin and
lightweight stuff.

I never ride without them. I also have thorn-resistant tubes in both
bikes (yes, also the road bike). In the MTB tires the liner is
additionally covered by a non-inflated slit regular tube to prevent
chafing. All this increased the weight of each bike by a few pounds but
not having flats is so worth it. Didn't have a flat in years and I ride
through some nasty turf which includes lots of these thorns:

In observance of Murphy's law they usually lay on the ground with the
long protrusion pointing upwards.

I sanded the tube, applied the patch and clamped it in a vise for an hour.

It takes just a few seconds of _high_ pressure to bond (not sure
if "vulcanize" is the correct term?) and then you can immediately
check it.

Note: please read the netiquette before posting. I will almost never
reply to top-postings which include a full copy of the previous
article(s) at the end because it's annoying, shows that the poster
is too lazy to trim his article, and it's wasting the time of all readers.

If the wire was dark-copper colored, it was probably a car tire belt
wire. The wire used in car tire belts is bronze plated carbon steel. The
carbon steel rusts away pretty quickly in most climates, but the bronze
protects it somewhat from corrosion.
