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?
Those who are serious about not getting flats make their own mr
tuffys from old tires
How do you do the overlap? It has to be cut because the radius
inside is a smidgen smaller than normal.
I was thinking about making my own Mr.Tuffy from a 2nd
thorn-resistant tube that is slit open lengthwise on the rim side.
I'll see when the new tube gets here next week. There should be
enough compliance in the rubber so there won;t be any wrinkles.
Hopefully. The othe issue is that the smallest these tubes come is
700 x 23/25mm and even 23mm is a bit large if there is a another
thick tube in there.
Fraid I either did not ask or don't remember. I remember the part
about removing the bead, but that's obvious. Mostly I remember the
conclusion, made simply with no effort to convince: "... and I don't
get flats".
Check it out. This guy rides 28s, and makes liners out of old 27s, so there is no cutting or overlapping necessary.

Good idea, though I wouldn't know anyone who still uses 27" wheels. Some
27" tires are still sold on EBay. But first I'll try the Mr.Tuffy which
should be here in a week. Until then the MTB will be pressed into
service despite an ailing BB. Carrying a spritz of turbine oil along in
case it starts screeching.
