Yesterday I had another two (!) sidewall punctures. Long story short I
will definitely not recommend CST Conquistare tires. Wore out in less
than 1200mi and then weakened which is just unacceptable. So thumbs down
from me.
This brings up two questions:
1. The Mr.Tuffy orange liners for 700c narrow tires. They must be laid
in with a wee overlap. Will that overlap cause a 700c 25mm tire at
110psi to run bumpy? Like whop .. whop .. whop every time the overlap
comes around?
2. What about taking a second (otherwise discarded) thorn-resistant
tube, slit it open on the inside and slide it over the real
thorn-resistant as a 2nd layer?
The problem is that Kenda seems to have discontinued selling
thorn-resistant tubes with good and most of all same thickness all
around but now the thickness tapers off towards the sidewalls. That's
where they fail. Same for Sunlite which I had to re-order yesterday
because those things are essentially unfixable with those thin REMA patches.
Any words of wisdom? As usual, weight absolutely does not matter.
In case anyone knows: I read somewhere that smugglers "inflate" their
vehicle tires with some sort of hardening sealant (Silicone?
Construction foam?) that makes the tires bullet-proof. What material is
it and how do they get it in there thoroughly enough? Would it be good
for a couple of thousand miles?
I don't know about smugglers but yes you can buy foam to use in tires.

and I assume other sites.
Thanks. Tyrfil is what Andrew brought up and I'll contact them next week.
I'd like to have a similar firm tire behavior as if it was pumped up
with air to 110psi. Riding comfort isn't very important, durability is.
A google search for "foam filled bicycle tires" gets 372,000 hits.
such as:
https://www.amazon.com/Bell-Solid-No.../dp/B01HY12VOU
http://www.instructables.com/id/No-more-flat-tires/
http://www.livestrong.com/article/22...-tires-review/
I did web searches. None of the result were much good. I was looking for
something that works, preferrably via squirting through the valve stem
into a regular tube. There was a report of smugglers who had inflated
their tires with something from cans and that made them not go flat when
shot at. Unfortunately the report did not state what was in those cans.
The main objective of my post was different though, this was just a side
question in case anyone happened to know.
