Tubes.

So... I'm about to change the tyres on the XT for some knobblies. I
really, really, don't want to get punctures and these are tubed tyres.

Now, Michelin does an inner tube with a wall thickness of 4mm and I'm
thinking about changing to these to minimise the chance of a puncture.

I've read in some places (contradicted by information in other places)
that these are off-road only but I can't see any reason why they
wouldn't work on the road *unless* they have a problem with heat
dissipation?

Anyone know anything on these? Safe to use or likely to end in a (post
fitting...) puncture?

 

If something sharp makes it through the tyre an extra millimeter of
tube is going to make sod all difference. Knobblies implies off road use
so low-ish pressures, a thick tube is not going to stretch so easily so
you would need to make sure you have the exactly correct size for the
tyre.

Sounds like snake oil to me.

 

Thank you for your kind contribution.

Anyone with some relevant experience/knowledge got some input?

 

Dunno about those tubes, but given you're using tubes how about some
sort of puncture proofing slime? Seem to work well enough for
mountain bikers, and given you're putting it in a tube, you don't need
to worry about making a mess of the rims.

 

I wondered if that freezes since these tyres are likely to get pretty
cold.

Have used that in tubeless tyres and it's been pretty good (well, good
in that I've never noticed a puncture in well over 100k miles of using
it).

 

Well, a mousse isn't any use, ignoring the price. They aren't rated for
high miles and fall apart with time. Good for off road, but not on
road. I have a little, recent, experience of these.

Problem is I'm talking about temperatures as low as -20... and in this
case I'm worried about having 500g of slime in a lump at the bottom of
the wheel. It would take a long time to warm up with the road being
cold. I'm surprised I can't find a temperature rating for it. Surely
they should be stating the conditions under which their product can be
used???

I was under the impression that Slime and similar pretty much smeared
themselves all over the tyre and stuck there (evenly distributed) after
first application. Otherwise it would pool at the bottom every time the
bike stopped, and throw the balance out until re-distributed.

Given that the instructions explain to go and ride and distribute it
after 'installation' but make no further mention of it, this seems, at
least IMHO, unlikely.

YMMV

Iced ones maybe.

 

Slime's FAQ says the stuff for inner tubes will pool if left to stand. With
tubeless tyres the inside is rough, so the Slime mostly stays in situ. The
inner wall of a tube is smooth so the Slime cannot grip in the same way and
will eventually pool. As burnt says, they don't specify a temperture range
where this pool can become a lump.

 

Ahh, that makes sense.

But where there's packed snow they give you some chance of grip...
maybe.

Will try them and see how awful they are on the XT... may go back to the
Tourances.

Conti TKC80 may give you the best compromise. More off-road bias than
Tourance but deemed suitable for road use and is OE fitment on the R1200GS.
