Either way. That's the way it is.
WHAT CAN BE DONE ABOUT THIS?

I want to know why bicycle tyres aren't
manufactured in the United States.

Well?

Dear F.,

As Dave already pointed out, water lubricates the sharp
debris, letting it cut through rubber more easily. The usual
example is that cutting rubber tubing in a lab with a razor
blade is much easier if the blade is wet--much of the
friction between the newly exposed dry rubber and the dry
blade is eliminated.

The other reason is that wet pavement encourages more debris
to try to puncture your tire.

Normally, most pointy debris lies flat and harmless on the
road, so your tires roll right over it without injury--you
can ride right over nails without much fear of a flat tire.

However, the impact of your front tire sometimes causes a
piece of debris to bounce up just right to impale your rear
tire a moment later--the nail is momentarily pointing
upward, not lying flat.

The more debris that your front tire flips up, the greater
the chances that your rear tire will be punctured. Since
small debris sticks to wet front tires, a great deal more
debris is flung up when the road is wet and the odds of a
flat increase substantially.

To make it harder to repair them.

Slush is even worse. I swear it makes staples, wires, and bits of glass
stand sharp end up, *and* changing a tube on a slushy wheels ia about
the dirtiest job there is on a bike.

The puncturing object is lubricated by water, and can penetrate more
easily as a result. Some objects that would not puncture a tire when
dry will go right through when wet.

That said, I get far fewer punctures in wet weather...because I do a
lot less riding then!

Move to Arizona or Nevada, or build yourself a velodrome.

Some were. They were expensive by comparison to imported tires of the
same quality. Why weren't you buying them?

water lubricates it lmfao what twaddle is that then...

it is because in the wet... objects such as broken glass do not show up so
well on a wet road... so you dont see them and ride straight over them...
get some slime tube protectors and never get a puncture in the wet again...

Dear Pingu,

As anything begins to penetrate rubber, its sides are
pinched tightly by the rubber.

If the sharp object is dry, its progress is retarded by the
kind of wonderful friction that led us to use rubber on
tires.

If the sharp object is wet, we're reminded why we can't
corner nearly as well in the rain--water makes rubber
slippery.

If you're skeptical that water-lubrication helps cutting
rubber, take a razor blade or knife and try to cut some dry
rubber.

Now try again after wetting the blade.

This is why lab students are told to wet the razor blade in
order to cut it neatly with a single slice--otherwise, they
have to saw back and forth against the increasing friction
of the sides of the cut on the blade.

The other reason for more flats in the rain is that much
more debris sticks to a wet front tire, is flung up, and
therefore has a better chance of being in a position to
impale the rear tire.

Like nails, very little debris actually stands upright in
hopes of puncturing tires. Without a caltrop-shape, like a
goathead thorn, you have have to lie in wait for the front
tire to bounce you upright.
