Does anyone know good thorn-resistant tubes?

running 700c 25mm tires with an additional tire liner

Might go to 28mm in back some day.

The only time I ever lost 3mm all-around tubes was
upon violent
tire blow-outs (sidewall failure).

Joerg, you sure must be one hell of a rider in terrible
conditions.


Not really. I use my bicycles not much differently than
my car.
"Pavement ends" is not a reason for me to give up and
turn around. On
the contrary:

Today I had a large cut in my tubeless tire and that
was the last
straw. It is just too messy to use and fix out on the
roads. Back to
tubes and clinchers.


I think that's a wise decision. It you'd add a tire
liner that's even
better. Two of us three riders yesterday have liners,
one doesn't. Guess
who got a goat's head flat ...

I talked to a friend that does a lot of your type of
riding and he said
that you can buy tubes that have removable presta valves
in them and you
can shoot Orange or Stan's Racing sealant into them and
pretty much end flat tires.


The sealant in a tube I’ve used a few times over the
years, I’ve always
given up since they only seal very small holes, I’ve
always found they
puncture quite easily, make a right mess and not seal!


Yup. I used the slime stuff years ago. One fine day I had
slow leaks and barely got home. Next morning I found a mess
in the garage under the MTB. Same with other riders. No more
of that stuff.


Tubeless you can seal with those kits roadside apparently,
with both valves
will clog if one doesn’t clean or take care.

I found that switching to mildly less racy tyres on the
gravel bike solved
stopped the bike being a puncture magnet, and feels just
as fast/lively
etc.


For me it's "thicker is better". To hell with weight-weenie
concerns. Tire surface, tire liner, 3-4mm wall thickness in
the tube. That requires a hell of a goat's head to punch
through. On the MTB there is another tube around the tire
liner, gives extra protection and prevents chafing.

Of course, my dream would be some stuff I could fill the
tire with, no more air. However, that would envirnmentally
not be too good.


Have a talk with your local Bobcat or construction equipment
dealer:

If flats are a critical factor for you, there are several
technologies available. No matter how frequent your flats
are, running around over construction debris all day is worse.

That idea is decades old and produced a filler foam that is apparrenntly
okay for fork lifts and other similar slow moving vehicles. AFAIK, it
isn't up to dealng with the rpm of a bicycle wheel and IME its use isn't
that widespread.

I wouldn't worry about rpm if that related to rotating mass concerns or
imbalances, that wouldn't bother me. My MTB already rides with a
pronounced "whop-whop-whop" effect due to all that stuff inside the
tires. Getting a solid 100-110psi performance with foam is the challenge
AFAIK unless it is a material that hardens inside. Anything much lower
would seriously slow down a rod bike ride.

That's the manufacturer link (one of many). What you want

Yeah, but if they don't hear the loud rumble of a big Diesel engine and
instead see a puny road bike they'll just laugh their head off :-)

That was similar when I went to a Timken-Torrington dealer in Belgium
back in the days, to buy a few ball bearings so I can make a bottom
bracket that lasts longer than the usual junk. They laughed pretty good
but finally had mercy and sold some to me despite not having a business
account (which would also have required a matching business license).

Have a talk with your local Bobcat or construction
equipment dealer:
https://www.americanindustrialtire.com/foamfilled.htm

If flats are a critical factor for you, there are several
technologies
available. No matter how frequent your flats are, running
around over
construction debris all day is worse.


Someone had mentioned it here a while ago and I inquired.
Unfortunately that stuff is only sold in humongous
quantities. I guess it only makes sense if you own a serious
bulldozer.


That's the manufacturer link (one of many). What you want
is a local
dealer who sells tire fill as a service.


Yeah, but if they don't hear the loud rumble of a big Diesel
engine and instead see a puny road bike they'll just laugh
their head off :-)

That was similar when I went to a Timken-Torrington dealer
in Belgium back in the days, to buy a few ball bearings so I
can make a bottom bracket that lasts longer than the usual
junk. They laughed pretty good but finally had mercy and
sold some to me despite not having a business account (which
would also have required a matching business license).


Same thing, really.

A standard pack of 1/4" chrome steel balls in grade 25 is
4000 pieces in one matched sealed lot. That's what bearing
makers sell in the same way that tire fill makers sell drum
of this or drum of that.

I've known riders who went with foam fill and had it
installed at a Bobcat dealer for a moderate price. Not to my
taste, but it's just not all that difficult or unusual a thing.

Just had a Kenda thorn-resistant tube fail. It lost pressure

Does anyone know who still makes the real stuff, 3mm thick all
around? Or maybe another good version thorn-resistant tube? I am
running 700c 25mm tires with an additional tire liner in there.
Might go to 28mm in back some day.

The only time I ever lost 3mm all-around tubes was upon violent
tire blow-outs (sidewall failure).

Joerg, you sure must be one hell of a rider in terrible conditions.


Not really. I use my bicycles not much differently than my car.
"Pavement ends" is not a reason for me to give up and turn around. On
the contrary:

Today I had a large cut in my tubeless tire and that was the last
straw. It is just too messy to use and fix out on the roads. Back to
tubes and clinchers.


I think that's a wise decision. It you'd add a tire liner that's even
better. Two of us three riders yesterday have liners, one doesn't. Guess
who got a goat's head flat ...

I talked to a friend that does a lot of your type of riding and he said
that you can buy tubes that have removable presta valves in them and you
can shoot Orange or Stan's Racing sealant into them and pretty much end flat tires.


The sealant in a tube I’ve used a few times over the years, I’ve always
given up since they only seal very small holes, I’ve always found they
puncture quite easily, make a right mess and not seal!


Yup. I used the slime stuff years ago. One fine day I had slow leaks and
barely got home. Next morning I found a mess in the garage under the
MTB. Same with other riders. No more of that stuff.


Tubeless you can seal with those kits roadside apparently, with both valves
will clog if one doesn’t clean or take care.

I found that switching to mildly less racy tyres on the gravel bike solved
stopped the bike being a puncture magnet, and feels just as fast/lively
etc.


For me it's "thicker is better". To hell with weight-weenie concerns.
Tire surface, tire liner, 3-4mm wall thickness in the tube. That
requires a hell of a goat's head to punch through. On the MTB there is
another tube around the tire liner, gives extra protection and prevents
chafing.

Of course, my dream would be some stuff I could fill the tire with, no
more air. However, that would envirnmentally not be too good.

They are available. See:

Seen it but this does not instill confidence with me:

???? The photo is showing that with a load of 12.5 kg the tire
diameter is 50 cm whether air inflated or air foam.
