Flat Resistant or Flat Proof Tires

Do Flat Proof tire exist and are they worth owning. I can imagine a day when
I will be riding again (on something with 3 or more wheels that you don't
have to sink into) but I can also imagine that even the simplest maintenance
chores will be quite difficult.

There was something on the cab-bike web site about a flat proof tire being
codeveloped with the Greenspeed people. I contacted them about it and they
said it was either a back burner project or something that isn't actively
being worked on.

What are the best tires for flat avoidance?

Thanks.

Yes and Generally Not are the answers for genuinely flat *proof* tyres,
which are typically a closed cell foam construction rather than a
covering for a pneumatic tube.

Flat /resistant/ is another matter, and there are some seriously tough
tyres available. Schwalbe's Marathon Plus is an oft-cited example. The
basic Marathon is a tough kevlar belted tyre but persistent spiky stuff
can get through, the Plus version adds a deep puncture belt which can
take on thumb tacks without the tube going. Extra weight and higher
rolling resistance, but not unusably so if you're not out for Maximum Sport.

Dutch Perfects are also widely cited for being /almost/ puncture proof.

I have 2 tires nested on the front wheel of my Vision, plus an anti-flat
strip.

Wow...sounds beefy (and heavy!). What tires did you use? Did you need
to modify the inner one? Say, by cutting off the bead?

The tires are Primo Comets, one's a 1.5", the other's a 1.75". The
wheel's hub is an 8lb electric motor bolted to the fork, so I'm not
concerned with weight and I don't want to have to take the wheel off to
fix a flat.

This doesn't sound like too great an idea to me, because sooner or later
you WILL get a flat on the road and you'll have to undo this setup.

I had a bike come with Comets on it; after a flat I decided to switch to
tougher offerings. When taking the Comets off I noticed that the "tread"
area barely seemed thicker than the sidewalls.

The tires I went to were Marathon Plus', WAY thicker in the tread. I
haven't ridden the bicycle much (due to lousy IL winter weather) but
didn't notice much rolling resistance, in what bits of riding I have
been able to get off.

Plus I used "flat-resistant" tubes (tread area is 2X thick as the
sidewalls). I figured just for good measure I would carry another spare
tube in the cargo trunk of this bike--but the flat-resistant tubes are
too big. Just one takes up most of the room in the cargo trunk....

I use stan's tubeless setup on my mountain bike and they work great for
sealing small thorn holes. I would recommend researching if other people
have adapted them to road use. Kirk.

What kind of a jerk are you anyway? First it was a Rhoades, then
side-by-side tandems and now it is flat proof tires!

Do they not have mental asylums there in White Plains, New York? I urge that
you check yourself in as a jerk and a nerd. You will not be lonely as New
York State is full to overflowing with such types.

PS. I will be riding herd on all of Jeff Grippe's posts to this newsgroup so
long as he continues to tell others what to do with respect to me. If he
will shut up about me, then I will shut up about him. There is no other way.

You know in the Old Days when us kids all hooned round on single speed
steel bicycles and no one had ever heard of "quick release", you fixed
a flat by pulling the tube out and gluing a patch on.

I don't believe that method is no longer viable. Just more work than
swapping a tube.

I had Primo Comets many years ago, but one blew out "big time" in a
large garage- sounded like a bomb with all the echoes; and gave the
neighbors cat heart failure. Never saw that cat again; so now I swear
by Primo Comets for just that reason. Oddly, no more blowouts!

One rear tire I ordered was the older Schwinn Dragslick; just to be
different. Having 2.50" flat width looks good, but that tire does not
skid anymore- too much traction!
