Of anti-flat strip eg Slime liners...

To anyone dumb enough to follow my advice previously:

I have now had numerous punctures due to the Slime liners eroding away through the tube. The location has always been to sharp edge where the liners have been cut off.

So I thought I was smart and used some duct tape over the edges to smooth them down. Then I was dumb enough to dispense this advice of what I did.

Big mistake! The vinyl of the tape reacted with whatever inside and became hard, split and proceeded to cut my tubes to ribbons. Happened to both bikes I did this to.

So again, if you did this too, be quick and remove the tape before the same happens to you.

What I now did to try and solve the problem, is to sand the cut ends' edges smooth and round to try and prevent further flats. Fingers crossed...

Might it be possible to secure the slime liners inside the tyre with some kind of adhesive Jur? Maybe it would be possible to glue a patch of inner tube over the join between the two ends of the liner to protect the tube.

Just a wild guess.

I just removed the slime liners that I had put in my new (Schwalbe Marathon 20X1.5) tires. They caused a tube failure at only 12 miles on my new bike. There were no further problems after that, but I removed them anyway. I think the tires are a little livelier without them.

Rather than use Slimeliners, particularly on my MTB, I just simply line the tyre with an old tube, (cut the valve out first), that's 3 layers of protection for the tube...it seems to work very well, it just makes the feeling a bit looser. The same should apply to road tyres, only it might be a little harder to install.

I dumped slime liners for the same reason and went with slime tubes. We'll see...

After several punctures from glass in the road, I installed Slime liners in a bike I use for utility/city riding. I was concerned about the sharpness of the end cut so I shaved and sanded the edge smooth. I used contact cement at a few spots to hold the liner in position whilst reinstalling the tire and tube. Three years later and so far no more flats.

My experience has been similar. I find that tube failures are the result of putting too much air back into the tire after the liner was installed. The liner takes up space in your tube so you have to lower the pressure by at least 10 psi or it can blow!

I read that if the slime tubes bust there's a real big mess.

Try a white Tubular Tire glue, such as Wolber. It is meant for use with tire, tube and rim materials, so it should not react with anything. Spread very thin and allow to get tacky. It provides just enough adhesion to hold everything in place without leaving a lot of mess behind.

I used to use it to hold rim tape in place on my road bike clinchers. Before I tried that, the tubes used to shove the tape aside and slip into the spoke holes. I would then get a flat with 4+ holes and 5 almost holes.

When my wife began to have frequent flats I looked into the Marathon Plus tires for her, unfortunately they are not available for her wheel size. Our second choice ( Bontrager Hard Case ) has worked out well, as so far she has not flated.
