Bike Tires

Back in the day I used to ride Continental Grand Prix 19 and 20mm
tires which had "unsurpassed puncture protection" and now on my
Bangkok bike I have Continental City Ride's which have "Puncture
Protection".

But I still get punctures and the number seem to be dependant on the
thickness of the tread, not on the "Puncture Protection". What brought
this on was a puncture I had yesterday on my usual Sunday ride. A tiny
sliver of metal punctured the middle of the tread and made a pin hole
in the tube. With the thinner Grand Prix I used to get even more
punctures, with a worse case of two punctures in about 100 yds :-(

I'm beginning to wonder whether there is any value in these puncture
protection schemes, other then possibly contributed to the sales
price of the tire?

I use Specialized Turbo Pro tires. Ride very well and I haven't had a
puncture flat in years.

Yes. Way back in the dark ages I used to use sew ups and on the roads
I was ridding on in Indonesia, wide open highways with little traffic,
I don't remember ever having a flat. Then I retired and we came back
to Bangkok and I couldn't carry enough tires to get a ride in. I think
I once went through 4 tires in 15 Km.

Since then I've gotten older and perhaps wiser and I've forsaken the
skinny tires for more normal widths and of course thicker tread and
far fewer flats.

But the advertised "puncture protection" still irks me :-) But I
suppose it is kind of like a St. Christopher medal on the car
dash..... maybe it helps :-)

I doubt that roads in Indonesia are worse than Quebec. I doubt that
roads in Sarajevo are worse than Quebec. My wrists still hurt from a
100k ride yesterday morning. lol

Just saying that it seems to work with the tires I have. I don't think
it's a marketing scheme. Anyway, cycling communities are pretty chatty
about such things. If they didn't work I doubt that they'd sell much.

The roads in Bosnia are worse than the roads in Quebec. I've driven
in both places. Bosnia has some new, excellent quality, motorways
(narrow and twisty by North american standards, but wonderful by
Balkan ones), but also has some roads that aren't worth calling roads.
The average road is not good, and makes Quebec look wonderful.

My experience has been that they work. They're not perfect, and the
heavier and slower feeling the tire, the etter it works. I find lots
of little sharp things in my tires, when I bother to look, of the sort
that used to give me flats when I rode skinny fast road tires.

If you say so. I've never been there but it's hard to imagine.

Mine are 23c and pretty fast. I know what you mean though about the little
sharp things.

The protection is usually a layer of material that will likely resist a
cut from a small piece of glass or stone better than a poke from a sharp
and pointy piece of steel. The protection is often a woven material,
like kevlar, so pointy things can still go between the fibres.

Bosnia has some routes called expressways, which are 3/4 of a lane of
what might have at one time been paved. To one side, there's a
mountain. To the other, well, there *isn't* a mountain. I had to
backup hfal a kilometer along such a spot, because there was an
oncoming articulated truck. There are other places where the road
is used for storm water control, instead of a storm sewer. Our
average travel speed was 35 kph (for the whole balkan trip, it was
nearly 50...)

The contis he's got have what conti calls "gummy guard" or something, which
is a rubber layer below the tread, and above the carcass. It provides
puncture protection by providing a mechanical layer of protection, and
extra thickness. (Conti have several different puncture resistant
protection, ranged from kevlar belts to other fabric belts, to
several different rubber layers. It's incredibly confusing, and I
have no idea what they think is more puncture resitant than wat. )

I have a set of conti country tourting mumble mumble mumble on my
commuter, I don't particularly like them, they're heavy and stiff, and
don't have wonderful wet performance. But they're damn near flat
proof, and refuse to wear out. (One or two flats in something like 2k
miles, and the rear is just starting to look worn.)
