Default Conti Contact Security vs Schwalbe Marathon Plus cycle tires

http://www.conti-tyres.co.uk/conticy...security.shtml

Continental, Germany tells us the Contact Security is

"Designed for industrial applications, the ContactSecurity can also
perform well in everyday use. Its massive puncture-proof breaker was
developed to resist metal cuttings and shards on factory grounds. In
view of its tough construction, it is not a comfortable touring tyre
with low rolling resistance, but it does effectively ward off gravel
and shards on short stretches in the city."

How do these compare for puncture protection, speed and mileage
against the Schwalbe Mararthon Plus ??

Thanks

The page also says "The tread derives itís superb function from a closer
look at natureís solutions. Animal paws were the model for designing the
tread pattern and itís surface!"

How many animals have wheels and travel primarily on pavement?

I note that the 26" version is only rated up to 58 psi, and they recommend
only 45 psi. That seems incredibly low for a road tyre. Does the stiffness
of the construction make up for it? They do say:

"The Contact Security is designed for commuters who simply can't risk a
puncture; people who want a no-hassle ride to work when speed and rolling
resistance is not an issue."

Which implies poor rolling resistance; maybe that's part of the reason.

Dutch Perfects have a similarly low pressure rating - I just ignore it
and put a ton in anyway - so far, so good.

"The Contact Security is designed for commuters who simply can't risk
a
puncture; people who want a no-hassle ride to work when speed and
rolling
resistance is not an issue."

an accurate statement.
when speed and MITTY PRO RACER EFFECT SYNDROME are not issued.
Conti designs around (?) a responsive sidewall. Seems that way as
often a Conti sidewall is the tire's weakest area, when loaded with
rubber as on the Security, less responsive than a TT.

I carry groceries and camping equipment. The Security used here as a
rear tire with a TT front was always (now at the end) pumped to near
90-100 pounds. At higher pressures, the tire is slippery during the
break in miles. Slippery as overloaded slippery tho I ran it unloaded
and it was again slippery. I assume I reduced the contact suface above
a thick belt. ??? I don't know if that's logical.

Never treid it at recommended pressures. That's from using the TT.
Recommended TT pressures, I consider largely imaginary as one curb
drop, I used non progressive bifocals, and whoooola! a cut sidewall
from impact.

Never had a flat. Is the tire fun for zipping around? sure, why not,
even when slippery.
itsnot a question of: is this tire dangerous
itsha question of does the tire conform to Mitty Syndrome or Pole
Disease.
would I buy another. yes, if the debris content is high. I would try
sanding the contact surface.
cam I compare it to a Schwalbe? what planet are you from? I have
Pasela Messengers. They're on strike. There's a comparison. The
Messengers are wooden but grip, The Security isnot wooden and is early
on slippery at lower cornering limits, at high pressures-necessary hi
pressures.
I have a Schwalbe Big Apple, unrun. It looks like the PR: new factory,
new capitol, new technology. Looks a lot like a Pasela Messenger but
thinner.

I would be wary -- overpressure failures may not manifest immediately,
and will tend to fail out the sidewall.

i did something like that to a $$$ studded Nokian tire a few years back
in an ill-advised attempt to lower rolling resistance. I ran it at 100+
psi instead of the recommended 65 max and blew out a sidewall after 4
months. Front wheel. Fortunately it happened while it was parked in my
office and not out on the ice.

I haven't tried the Continental Contact Security and, having read what
the manufacturers say about it in the sections you and Tom quote, I
won't be trying them. I do however have experience of the Schwalbe
Marathon Plus and the very similar Bontrager Satellite Elite Hardcase,
which are everything Continental says the Contact Security isn't: the
Marathon Plus and the Bontrager Hard Case are high-pressure, low
rolling-resistance tyres of exceptional puncture resistance; they also
have perfectly good grip in the wet, considering that their tread is
very low and the sipes are only at the sides of the tyres. I switched
to Marathon after a series of flats in, among others, Continental
tyres, that cost me about 125 Euro for new tubes and labour to fix
flats, and after several ruined rides in the same week bit the bullet
and bought the expensive Marathon Plus, and have not looked back; zero
flats in about another 2000km on the same roads. The Bontrager
Satellite Elite Hardcase came on my Trek "Smover" and has about 1750km
on the same roads that Contis (*not* the Contact Security) weren't
good enough on. The Bontrager tyres have nice graphics, if such things
matter to you, illustrated on my Trek "Smover" at:
http://members.lycos.co.uk/fiultra/B...20CYCLING.html

There is nothing to choose between the Marathon Plus and the Bontrager
Hardcase except that the Schwalbe tyre usually costs more even at the
discounters, though I must admit I haven't fitted the Bontrager to
rims yet (they came with the bike as a standard fitting); the Marathon
was difficult enough to fit, being enormously stiff, but nowhere near
impossible with patience. I wouldn't want to change a tube beside the
road though with these tyres fitted. I suspect the Bontrager will be
the same or a little more difficult to remove and refit as it feels
stiffer still. Neither tyre shows appreciable wear in around 2k klicks
on roughish roads. If comfort matters to you, you can have it on
either by inflating to about 60psi at which they are quite resilient
and do not add appreciable drag through higher rolling resistance, but
I have suspension seatposts and forks on both my current bikes so I
pump them up to about 85psi for minimum rolling resistance, at which
point there is no rolling resistance penalty over any other tyre I
have ever used; inflate higher still and the action becomes a bit
jiggly on poor roads and the suspension starts working harder for its
living.

As you can guess, I'm a big fan of the Schwalbe Marathon Plus and the
Bontrager Satellite Elite Hardcase -- I hate flats.

One necessary comparison: using a Specialized thornproof or thornproof
plus slime tube in a sportier tire fills the bill excepting a thicker
sidewall. Thicker sidewalls are not so thicker tho...that's a toss up
depending on condiTions and riding habits.

a thornproof in a Security doesnot normally flat

Contrary to common opinion, for any given rubber compound, (on bicycles)
slick tyres are better in the wet than tyres with tread. They also tend to
roll slightly better. Bicycle tyres with tread are only beneficial on soft
surfaces, not on tarmac.

I am quite happy with SM+ for Chicago city commuting. I hate flats, and I
don't get any.

As far as I am concerned (personally), this issue is closed.
