The claim is that it "instantly seals punctures up to 1/8" as you
ride" and "works repeatedly, lasts up to 2 years"...how's this
possible -- and how's it that we're still using regular tubes, then???
Also, has anyone any experience with gluelss patch kits? How are
they, how do they work?
TIA!

Prisoner at War asked:
> Slime Self Healing PV Road Tube?
I think that some of the previous replies to this query
addressed the use of Slime tubes in tires that are larger
and run at much lower pressures than those on road bikes.
I've used Slimes on MTBs ridden on-road with 60 PSI, and
they seem to seal fast enough to retain some air; I think
this is primarily because it's easier to plug the leak at
pressures lower than the 100 to 125 PSI commonly used for
narrow road bike tires, and the air lost from the tube
during the sealing process has less effect because of the
larger volume of air in the fat tire tubes.
In my experience with Slimes on road bikes, they may seal
a goathead puncture, but the tire is likely to have lost
too much air to keep riding on it. It may be easier to
just reinflate the tire rather than hassle with a patch
or tube replacement on the roadside, but that's about the
best you should hope for.
Slime is more likely to clog Presta valves with internals
that aren't easily removed or replaced like the Schrader
valves more commonly used with wider rims and fat tires.
Also, as other folks have said, it can be a real mess to
clean up after a leaking Slime tube, especially if it's
your only option for a roadside repair. On balance, my
vote is: Slime for MTBs - maybe; road bikes - NO.
> Also, has anyone any experience with glueless patch
> kits? How are they, how do they work?
Glueless is a blatant misnomer. These clear polyurethane
patches use glue to attach to the leaking tube, just like
conventional black rubber patches. They don't require the
separate application of 'glue' from a tube as a surface
prep before sticking them on the tire. Some of these
patches 'work', at least marginally, temporarily. If you
clean the area with an alcohol swab, let it dry and apply
the patch carefully, let it set awhile and don't disturb
it in the process of remounting the tire, one can be a
viable 'quick' fix to get back on the road. It's probably
a better repair than a hastily, sloppily applied 'glued'
patch. Again, I found them much harder to apply on small
section road bike tubes, and less successful than on fat
tired bikes. Even when I use one on an MTBs, I still try
to remember to replace a glueless patch with a glued
rubber patch once I have the bike back home. The most
common failure I've seen with PU patches is a thin line,
sort of like a wrinkle, from hole to outside edge where
the patch comes unbonded from the tube, and forms a slow
leak. Another thing that can wreck a repair job with a
'glueless' patch is inflating the tube outside the tire;
PU patches just don't stretch as well as rubber ones.
Again, my vote is: if you have the time to apply a rubber
patch properly, use that rather than a glueless patch. If
you're in a bigger hurry, swap the tube.

A blowout will clearly demonstrate why many people hate that stuff.
Suddenly you've got sticky green crud all over everything.
A flatted tire full of Slime squirms like a bare rim on pavement.

I have punctures about once every two years on average: it just isn't
worth it for me. The sort of thing that will get through a Marathon and
let a tyre down is quite possibly past slime's capabilities in any case.

We still use traditional tubes, because a single Slime tube will weigh
more than a pair of tires AND standard tubes combined.
Just use Tufo tubulars - most reliable tire ever and the reason I still
ride on tubulars on all of my bikes, including my mountain bike.
If you don't use standard tubular rimes, you can also get almost all of
their tires in a clincher version. The tire does not contain a tube at
all, and uses a sealant (absolutely nothing like the slime compound) to
fill punctures. I am on the bike 20 hours a week and have been using
Tufo tires for over 15 years. In all that time, I have never, ever had
a flat tire - except for almost every race where I am not allowed to use
Tufo's.
Any shop can order them from the distributor in Canada, or from Airo
International in California.

Dear Kerry,
The same races where anyone who doesn't use Tufos with sealant added

Dear P & P,
A road Slime tube weighs 180 grams--see the specs tab. Two of them
weigh 360 grams:
http://www.performancebike.com/shop/profile.cfm?SKU=4633&subcategory_ID=5411
A road tube of similar thickness weighs 117 grams--again, see the
specs tab. Two of them weigh 234 grams:
http://www.performancebike.com/shop/profile.cfm?SKU=2294&subcategory_ID=5411
You can get lighter Slime tubes and light ordinary tubes, but this is
enough to make the point--a pair of Slime tubes adds a total of about
126 grams to a 700c bicycle and rider.
A 158-lb rider and an 18-lb bicycle weigh 80,000 grams. Replacing the
ordinary tubes with Slime tubes adds 126 grams.
126 / 80,000 = 0.1575%
It is doubtful that any rider can detect a 0.1575% total weight
difference while actually riding.
Slime tubes are not popular for several reasons:
1) Exaggerated fears of weight penalties--see above.
2) Fuss and trouble with the tire valve and air pressure gauges. The
green Slime and wispy white fibers can clog things.
3) Exaggerated expectations concerning sealants. Slime works best at
sealing pinhole punctures from goathead thorns, not at sealing larger
punctures and punctures higher up the sidewall.
4) Most of all, few riders suffer enough flats to see much benefit.
I use Slime tubes because goathead punctures are about as common where
I live in Pueblo, Colorado, as rain is in Seattle. I don't carry a
rain jacket on my daily ride, so I can understand why few Seattle
riders bother with Slime tubes.
So far this year, I've had only 8 flats in 87 fifteen-mile rides, all
from goatheads. About half the time, I find the flat tire the next day
and can fix it in the comfort of my garage because the Slime let it
hold pressure.
Slime tubes probably aren't worth the trouble for glass, nails, rock
chips, and big thorns.
But I find Slime tubes darned useful for goathead pinholes.
Cheers,
Carl Fogel

I like Slime Ultralite tubes. They don't have the white, whispy fibers.
They are a little heavier than regular light tubes but have a nice high
collar around the stem. Stem/tube separation has never been a problem as
it has with so many other Presta tubes I have use. I don't, however,
like the Slime itself, so I remove the valve core and squeeze out as
much of the Slime as I can, and just take my chances with goatheads. The
Slime is quite toxic to grass, BTW.

Dear Ken,
Glad to hear that you found something that suits you, even if it takes
modification.
As for killing the grass, practically any thick but non-toxic liqud
will kill grass if not hosed off.
Slime itself is edible.
The page that I used to link to on the Slime site has vanished, but
your ice cream probably contains Slime's chief ingredient, propylene
glycol:
