I want to hear from people that are bothered by tire punctures in bad weather bad enough that they are not afraid of racer doctrine like “it’s too hard to steer” and “it will slow me down 20mph” just by using a few extra ounces of rubber in their tires. I will admit to riding slow.

I have 6 tires on my bike so when the front tire gashed open I didn’t even slow down. I didn’t even feel the slight bump until I crossed a smooth stretch of pavement.

I want some one to try this and let us know how excellent it is. Not how bad it is.
You could even test it on broken glass if you have a used tire.

I have not tried that but do run Schwalbe Marathon Plus tires on the bikes I am most concerned about flats on, my Big Dummy and Swobo Dixon. I also have Schwalbe Stelvio Plus tires on my IGH drop bar road bike and Panaracer Ribmo Protex tires on another narrow tire 700C bike.

All are quite resistant to most broken glass and other common road hazards though I try to avoid glass when I notice it in time. Where I live goatheads are one big summer tire hazard.

I am not so paranoid about punctures that I see any need to run 6 laters of tire on a rim, in fact I would think that with most tires and rims that would leave no room for a tube. I do carry a spare tube, patch kit, tire levers and a good pump on all my bikes.

Looks OK,How would you cut a suitable tyre?Would the edges need smoothing?.I have seen marks on an innertube fron the edge of a liner.

I've never needed to do this myself, but I've seen a tire with a tire tread between the tube and it's inner surface. The guy literally cut just the tread portion from an old tire. He said it worked great against all the little puncture thorns where he lived and had it on his full suspension recumbent.

So now you’re saying that I am paranoid? The denial of this concept is incredible! And I didn't say 6 layers on one tire.... actually one extra tire works good.

I really do not want to hear any more excuses about how this is a bad idea! I want to hear some POSITIVE feed back!


Do you run your tires until they are nearly worn out? I do, and that’s when they really need an extra tire. As you can see in the photo there was still tread left when it opened up for no apparent reason.

If it works for you, fine. I would expect high weight and rolling resistance. Any positive feedback would require someone else to duplicate your setup and use it for long enough to determine for themselves how puncture proof it is and if the tradeoffs are acceptable to him/her. I do not have enough old tires to cut up to even try it and expect few others will either.

The same is true for airless bike tires. Some who have tried them find them satisfactory while many others have not found the tradeoffs for complete puncture proofing to be acceptable.

Please do not expect a pat on the back for having come up with what I would expect to be the heaviest possible pneumatic bike tire, no matter how puncture proof.

Fat Tire

I just use Michelin DH race tubes, 1.3mm butyl, it's a tube for down hill racing but instead of being very light, its "thornproof" weight. Cost more than a chinese tube, but far more reliable. Very consistent thickness, no thin spots. 26" up to 2.8" diameter.

A tire with the bead cut off inside a tire as a liner is very old school. It works very well. One of the old discovery team members said they do it and lose about 1 mph. That sounds about right. No problem for training. Not good for racing.

I've had the edge of Mr. Tuffy tire liner eventually cause a long non-repairable tear in the inner tube, heck I've even had the edges of a carefully folded dollar bill boot cause a similar cut in my inner tube when I left it in my tire for a week or two. Based on my experience, I believe the inside surface of the tire's casing needs to be very smooth if you ride a lot, or you will have tube failures that cannot be patched (worse than normal puncture).

I ran over a large piece of glass today that opened my tire. I used a dollar bill to get me home. Yes my tire is rotten and should have been replaced already.

In Internet slang, a troll is someone who posts inflammatory, messages in an online community, such as an online discussion forum, chat room or blog, with the primary intent of provoking other users , or of otherwise disrupting on-topic discussion.[2]

try using a thorn risistant tube.

qmsdc15

Thicker tubes to prevent a problem caused by tire liners?? I don't use tire liners, so I don't need a solution to that problem.

jawnn

Well I would use a new tire with the bead cut off, the sidewall left on and a thorn tube. But its hard to add an inside tire if using 1.5" tires. That’s why I started using 1.75" tires.

I can see most people will just have to live with an occasional flat tire. I also suspect that most people do not ride in bad weather.

You can also scrape the sharp edges of the Tuffy liners, they have a bad reputation for cutting tires

Grishnak

OK,I now have 3 tyres on each of my folding bikes.No speed loss yet,still rolls down the hills as fast too.I will try is for the life of the back tyre.

You can't ask just for positive feedback. Well, you can, but you shouldn't expect it. You're going to get feedback, both positive and negative. You were not trolled.

Some people aren't afraid of changing the occasional flat. Some would prefer to buy a higher quality tire/tube than go through the hassle of using two old tires.

If you don't want people to comment on your idea, keep it to yourself.

Getting back on track regarding puncture proofing.

I like to use Kevlar bands between the tyre and the tube, along with adding either Slime or OKO to the inner tubes:

Many British rural roads are plagued with thorns from the hedgerows, which has over the year caused many puntures in the tyres of my bikes and cars.

I have a preference for OKO, but only because I have used that in tyres from the 16 X 1.75's fitted to my bike trailer, right through to tyres on large agricultural and construction equipment ..... and I have never experienced a single problem or failure.

I used to line my tires in the 70's with an old tire. It's old technology since we didn't have Mr.Tuffy's back then, but it worked very well. Kudos for thinking outside the box!

vegenaise

is english your second language? because it's really poor. and you saying you only want positive feedback is laughable. whats the point of even posting it, at that point.

qmsdc15

Well written.

vegenaise

there is a difference between not knowing how to spell and not caring/being lazy about proper punctuation.

ex: "So now your saying that I am peranoid? The denial of this concept is incredable! And I didn't say 6 layers on one tire....actualy one extra tire works good.

I realy do not want to hear any more excusses about how this is a bad idea! I want to hear some POSITIVE feed back!


Do you run your tires untill they are nearly worn out? I do, and thats when they realy need an extra tire. As you can see in the photo there was still tred left when it opened up for no aperaent reason."

This is a classic Harassment encouraged by others. A fine example of how forums operate:

Harassment occurs when a member insults, attacks, and denigrates another member at any time. We have zero tolerance for taking an argument about a any topic to a personal level. For instance, the use of terms such as "idiot, moron, stupid" and other derogatory terms constitutes harassment. The idea is to make this a pleasant environment to discuss cycling, not a schoolyard, or name-calling and rock-throwing festival. Repeated critical and sharply negative posts toward a forum member can also constitute harassment. This applies to all content submitted by users including posts, avatars and signatures.

Personal attacks and inflammatory behavior will not be tolerated.
