Stop Flats2 Stop Flat Tire Liner 26x2.0-2.125 Single Brown

I've been using the thinner road bike tire liner ones for years and rarely have had a flat (usually related to the odd sidewall piercing) so after getting a couple of punctures in my MTB tires decided to try these wider versions.

Just like the thinner road bike liners these work perfectly and have not had a flat since then. These are somewhat wider than the thinner road bike ones with a transparent strip on either side of the thicker inner (colored part).

There is a bit of a technique to getting a new liner in and to stay in exactly the correct place when putting the tire on - though if you're not too concerned I guess you can just throw it in between the tube and tire and be done with it.

I normally set the tire on one side on the floor position the liner just right and put a touch of air in the tube position the tube in the tire - the slight amount of air holding the liner in place; then carefully look under the tube with a flashlight to make sure the liner is exactly in the middle.

I then stand the tire up and start to put one edge of the tube into the wheel not fully around and just enough to hold everything in place then let out any air in the tube that might prevent the rim from going on properly and install the wheel rim normally.

As I said above - if you're not too concerned you don't have to go through the trouble and likely the liner will be in a relatively correct position anyway.

These liners whatever type you get - will not make your tires and tubes "bulletproof" but they will make them much more resistant than without so that only the most serious punctures are likely to occur. The kind of stuff only run-flat tires or Amish buggy wheels would be able to shrug off.;

Stop Flat Tire Liner appears to be a quality product. We have had it on the bike for a few weeks now and so far so good. It seems wider and better constructed than some I have seen.;

I build rent service electric bikes. eBikes are much more prone to flats than a conventional bike. The increase in speed distance covered and additional weight all take their toll.
I was plagued with constant flats. More expensive tires have built in protections but they can be quite pricey. In fact a pair of premium tires usually costs more than the entire bike from a department store.

I began to use a combination of these stop flats along with thorn resistant tubes. I can report no flats at all since I started doing this. At one point when I was commuting I was averaging a flat per day.

I give a big thumbs up for these because they work.

The only reason I didn't give them 5 stars is because they're a nuisance to install. Because they are rolled so tightly in the package they come out wanting to curl up. If you stretch them out and let them sit overnight they become far easier to place in the tire.;

I've used several of these now on several different bikes. They seem to do a pretty good job of keeping stickers out of my mountain bike tires... though a goathead recently went thru one of them. Only negative I'd give is that they don't cover any of the sidewalls so if you get a puncture on the side they're worthless. I've now gone to slime tubes and so far so good.;
