I picked up a piece of glass today and got a flat on my third

though some people say that they cut easily.

The Pro4 Endurance tire rolled really easily - something that
the Power Endurance doesn't seem to do. Though that could simply
be personal opinion.

I'm selling a set of wheels and they have Specialized Armadillos
on them. They did not have more than possibly 500 miles on them
and showed a lot of wear. While looking at them one of them had a
real long cut but still no flat. These are VERY expensive tires.

But the flat I got today I'm sure I would not have gotten on a
Continental Gatorskin.

So it appears that Continental is still the uncontested king of
flat-proof tires.


I used to be of that opinion as well but not anymore. The Gatorskin
side walls are too flimsy. I tried four. Two of them signed off
prematurely with side wall failures and a third had a side wall
failure shortly before end of life.

They do last 2500mi in hilly terrain with my weight and riding
style but what good does it do if a side walls fail before that
mileage?

Still looking, haven't found a good tire yet. One that doesn't cost
an arm and a leg. So if a tire only lasts 1500mi I am not willing
to pay more than $20. The CST Conquistare I am using now has
miserably short life at 1000-1200mi. No TWI so you never know when
it is closed to the end. However, their side walls are good and
they can be had for $15. IOW per mile they cost about the same as
Gatorskins though I hate to subscribe to a throw-away mentality
like that. Hence I'll keep looking.

Joerg, it isn't very fair blaming Continental for your very peculiar
riding style.


My road bike is ridden normally. Yes, that include some gravel and the
occasional dirt road but that is something one has got to expect from
any roadworthy vehicle. I am not riding rocky singletrack with
Gatorskins, that's where I use my MTB instead which has much sturdier tires.

I would have never brought it up if I hadn't found lots of other with
the same problems:

I used to swear by the Gatorskins and had them on all of my bicycles.
And then I had some notable failures, always in the sidewall, with the
bead separating dramatically from the sidewall, often in less than 1000
miles"

He describes almost verbatim what I have experienced.


I have NEVER had a sidewall failure on Gatorskins and that includes
off-road riding my bike along the bay trails which includes long
distances of gravel trail and some heavily rocky trail.

And I've been using Gatorskins since they came out.


Well, out here and in many other parts of the country their side walls
fail. Looking at the tires that isn't a surprise. The side walls are too
thin.

Meantime I have found tires that do not have this side wall issue but
don't last long enough. So, still looking. I was thinking about
ThickSlicks until you mentioned that the rubber layer sometimes
delaminates. That would be a show-stopper for me because we have lots of
debris on the roads. Bike paths don't but half of my miles have to be on
roads.
