Question about tire liners

A great deal, well worth the money. I haven't tried kevlar in 20 years, long
ago it wasn't worth while. With teflon liners, I get less than a tenth as many
flats on city streets.

Unfortunately, this is a lot like asking "How high is up?" Any claims
about quantitative reduction must be taken in context; tire liners
might eliminate all punctures for one rider and set of hazards, while
reducing another's flats by very little. If you are getting flats due
to small, short things like bits of radial tire wire, the liners will
probably help a lot. If the flats are due to goatheads, the liners
will help, but you'll still need to carry spare tubes. If you're
riding at night in an area where hurricane damage is producing a boom
in housing repair and reconstruction, roofing nails scattered by trash
haulers will continue to be found by your tires for at least another
year...and the liners won't help much in that case.

Oh yeah and rode about 500 miles until I got my first puncture.

We get people coming in on a regular basis with flats, but they have tire
liners. What is the culprit 90% of the time? The tire liner itself. The
sharp terminal edge of the liner abrades the tube until it fails.

Upon inspection, the tire liner is chamfered the *wrong* way from the
factory, with the sharp edge against the tube. I use scissors to cut the
end of the liner off at an extreme angle, causing a smooth transition
instead of a sharp edge.

yeah the liner's overlap eats cheap tubes and requires rotation and
inspection. we'll try the chamfer mod - foam strip?
add these up for the beer bottle polka
two liners are better than one
kevlar belt ( keeping the tire round) are one more
aramid sidewalls
aramid sidewalls covered with rubber ( you're now leaving the GP
circuit and traveling into wooden tire checker cab country but take
heart one can flog the checker with as much enthusiasm as the carbon
special- you just leave the road at a lower speed-POR POR!!)
and self sealing tubes - the knee plus oltree hereat-

Yeah, I have a similar experience with Mr. Tuffies. Great product.
They do slow the bike down a little. But worth it.

K, I tried the 'Mr. Tuffy' thingies years ago and found them
underwhemling. Unless installed 'just so' they can cause flats,
and they shoot the handling characteristics of the bike. Very
heavy and clunky. I don't normally use them. At the time I
was in NM and doing some off-road riding and I got the tuffy's
to help with those dreaded puncture vines.

Last Spring I switched to using some Continental slicks
(SportContact 'safety system'😉. I didn't really pay any attention
to the tires. They worked and I didn't get a single flat all
year. Finally got a flat a few weeks ago. The flat turned out to
be a pinch flat from tire under-inflation. Once I had the tire off
the wheel and was inspecting it up close I noticed something
interesting. I found 4-5 little chips and shards of glass that were
flush with the tire. They had penetrated the tire up to the armored
material (aramid ?) and been stopped cold. On a nomal tire
every one of those bits of glass would have been a flat.

I then went and checked the rear tire, still inflated and on the
bike. I came across another two little chips of the glass
embedded in the tire. Again they had been stopped by the
armored strip. I was able to pick them out like thorns and the
tire was fine. I was impressed.

I've used tuffy's and kevlar tires in the past, and they just don't
work as well, IME. I live downtown in a campus town so there's
often loads of glass on the streets.

Anyway, I really recommend these new armored tires now starting
to come out. They really seem to work. Much less hassle then
dealing with the Tuffy's too.

I'd imagine they would work on thorns and glass, however if you
run over a nail or staple all bets are off.

Here's a link describing these 'armored' tires:

When I first purchased the tires I didn't even
notice this feature. It's only after using them
for a year and seeing how well they work that
I'm impressed. All commuters should consider
trying these tires. I'll gladly trade a little rolling
resistance for a tougher tire. Hate flats. They still
roll far better than tire+tuffy.

Kinda expensive tho, cost me $25-30/tire.

Duh, maybe if I'd taken the time to read your
post I would have noticed you're looking for 'bent
tires.

The Tuffy's definitely do help a lot with thorns, but
I seem to recall still getting a few flats.

The only question is whether you can stand the
terrible rolling resistance.

Well I did a couple of shorter rides, 20 miles and 24 miles and I
noticed the added rolling resistance. but it wan't enough where I am
going to take the liners out right away. I can get puncture resistant
tires if the liners prove to be very ineffective. But I just didn't want
to replace them so soon. They only have 500 miles or so on them.
