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?

Have you tried these? https://www.schwalbetires.com/flat-less

No personal experience, but I remembered seeing the ad somewhere.
