Yesterday I had another two (!) sidewall punctures. Long story short I

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.


I have used tires like that and have them on there now. However, they
are still vulnerable to thorns entering more towards the sides and then
.... phhssseeeeeooouuu. As happened on Wednesday, twice. This was not a
problem when Kenda still made the tubes that were several mm thick all
around. Unfortunately unobtanium now :-(
