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

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.

Unless the tires are discontinued (e.g. Schwalbe City Jet), or moved to
production in a country that results in a significant drop in quality
(e.g. Tioga Comp Pool).

that happened to me; i used to like vittirio (?) Courier TTs. kevlar
belted, pretty bullet proof, durable and i liked the colors. out of
production it appears, wish i'd bought a few extra.
