Con una anchura de 50mm, es imposible montarlas aún en llanta 67 (26×2.35) por lo que tuve que devolver. Las rojas (1.5-1.95) quedaron muy bien en otra bici, por lo que compré mejor esa medida, esperando queden bien en esta otra bici. Fuera de este inconveniente, las que ya uso en otra bici, cumplen su cometido de no pincharse, aunque si hay que considerar un aumento del peso total de la bici y una sensación algo distinta a las normales, particularmente en calles empedradas.

Contrary to some other comments, I found the installation of the Tannus 26×4 inserts was a breeze and went smoothly. I consider myself an average DIY skilled person, and I didn’t need any extra tools. I simply followed the provided instructions and it took about 10-15 mins per tire, once the rims were removed from the bike, to install and inflate (using an air compressor).
Tip: I found putting a small amount of air into the inner tube (just enough for the tube to have shape) prior to inserting under the Armour made the process easier.
I installed the Tannus Armour inside 1 month old Schwalbe Jumbo Jim Addix Speedgrip tires for my e-bike. These hard to find Schwalbe tires are fast rolling, lightweight and relatively thin, so I wanted to have the extra protection since I frequently venture into isolated areas, as well as occasional highway trips into the city that is 45kms away.
I run the tires at a higher psi (28-30) when I travel on longer trips on pavement, and I noticed there is little difference in the ride with the inserts. When I trail ride I usually run at around 15 psi depending on the conditions, and noticed that the ride is a little firmer than before, but the traction and handing is pretty much the same. I have yet to try them in mud or snow at an ever lower psi (8) and will have to wait until the fall/winter.
It’s too early to speak of the puncture protection, but with my new Schwalbe “snakeskin” tires being so thin, I definitely have a much higher level of confidence in avoiding flats. I will update this review should anything change.

Three main points:
1. The tubes
2. The roll-flat-ness
3. The installation
1. The first innertube (of three) popped on initial inflation — just past 10 psi. Both the insert and tube were installed correctly. The second innertube deflated less than a block down the road — the valve came completely off. It was also inserted correctly. Third tube emptied of air a mile into a 2-mile commute.
2. The roll-flat function of these guys is nonexistent — there is no rolling, and the tire is definitely as flat as it would have been without the insert. (I know, because walking miles with a flat tire is exactly why I bought these things…) On this third tube, I had to get off the bike and shuffle it down the sidewalk because the tube came out of the tire and started to wrap itself around my axle, about a block or so after the audible pop. (I had to cut that third tube off, and remove it entirely.)
This mile walk also shredded my rear tire, causing me to have to buy a new one.
3. Installation isn’t really that bad. Essentially cramming a tire inside another tire, then trying to fit a tube in there… is gonna be weird and require some work. I thought/hoped it would be worth it. (It was not.)
I can’t rate the puncture resistance, since the bike never made it far enough to get punctured.
These bad boys look good on paper and in the sweet graphics, but execution is a complete joke. Three innertubes in less than a mile of flat, level pavement is nuts.
The cost of these POSs, the extra cost of buying a new rear tire, and new tubes, has made this experiment VERY not worth it.
In any case, there are two positives. First, I have A LOT of extra innertube rubber to use for patches in the future (though I honestly don’t know if I trust the salvage off these tubes). Second, I’ve got these two sweet pinkish floaty-donut things that might actually make a decent core for wreaths this holiday season…
Seriously, folks, avoid these. Just invest in quality spare tubes.
Linda Abegglen –
Easy to install, bought them for one bike to test them out and decided to get a second set.
Reviews claimed of having a flat tire after installing, but believe it is because they got there tube pinched when installing. Have not had a problem.
Ben –
Initially it appeared bulky for the tire. After inserting it I was pleasantly surprised at the ease of it fitting. I’ve been on several rides and have not gotten any flats! As far as weight it’s very light. I would definitely buy it again.
Christine H –
I really like them . The install was a little more difficult. I have already gone on 3 rides and no flats. I’m very happy. Thanks.
R. Gravel –
I put the liners into the tires and the next day the one tire was flat. One of the tubes are defective. Contacted company and they sent me 2 new tubes.

I bought 2 sets of these for 2 fat tire mountain bikes that are ridden only in the mountains on marked trails and roads. Installation was a bit more physical than we expected. Lots of wrestling with the tubes, inserts and tires before we got them in there correctly, but we got it done. We liked how lightweight the inserts are compared to other inserts/liners.
We like to ride with low pressure on the fat tires and quickly found out that this was not going to work with the Tannus inserts because the tube needs to be fairly full to keep the insert and tube/valve from moving inside the tire. Not having as low of PSI is definitely a negative for us.
The next issue was that after only 4 months I got a flat. Riding it flat was not an option, and I’m guessing this may just be the case for the fat tires with inserts, but again, a major negative.
Overall, not exactly the performance we were hoping for, but they’ve probably saved us from some flats we would have gotten. If these weren’t so expensive I’d give them a 4 star.
Stefan Clark –
This insert is very light, and fits snug on rim,. Upon installation make sure the valve stem of the tube is straight, because once it’s in it’s nearly impossible to adjust, like I said snug fit on rim. Fill tube and release air a couple of times to adjust proper fit of tube inside the tire to avoid a bunch up or ripple on sidewall. Product is working well for me, with a smooth ride.
A. Diamond –
I had these in my mountain bike for a while, but they changed the feel of the front tire when turning over roots and rocks. With these inserts, the front tire seems to hesitate slightly when turning over an obstacle. I suppose I could adjust to that as others have, but I didn’t really like the feel, so I moved the inserts into an electric bike with 29 inch Hookworm road slicks. They work well there, and they substantially dampen road vibration.
Some people have complained these are hard to install, but they’re not if you follow the online videos exactly. Also, some have complained that these require different tubes. The manufacturer includes a high-quality tube with each insert. If you need to replace the tube, a 700 x 38 gravel bike or touring tube fits just fine in the insert for a 29 x 2.5″ tire.

Bought our boy an e-bike for work and he got a flat the first ride. I’ve been a cyclist all my life so I was just going to get heavy duty tubes and slime, but saw these and thought we’d try something else. Our boy is about 250, is hard on bikes, and the roads here have a lot of debris. This inserts really work. Just one issue since installing them and over 100 rides, and nothing could have prevented that. If weight isn’t as much of an issue, don’t think about it, just buy these.

I had been riding everyday for over a year and never got a flat – and then 2 in a month. I have an e-bike with a hub drive. Repairing and changing a tire is a challenge. With this I now have the peace of mind not to get stuck on the trail. Should have gotten it much earlier.

The media could not be loaded.
Things to know. Have a tire lever tool to get off your tire to start the process. Have a valve stem remover to control your inner tube and electric air pump that can read psi. Have decent sharp scissors as you will likely have to trim it. The process is straight forward. If you try install it right out of the box it is far too big so you will likely need to trim it first. I am installing 26×3.0/4.0 tannus armor. You can see the picture of what it looks trimmed vs not trimmed. The tannus armour should stick out only a little out of your tire. Put in the armour first and then put one side of the tire and armour inside of the ride. Use the ground as your leverage to the rim down and push the tire and armour down to snug into the rim. If the other side is having a hard time to go down. Make sure release all the air by removing the the inner tube valve stem and then push down on all your tires to remove the air and it should go in super easy. Took about 45 minutes to install both.

I installed these inserts before heading to AZ for months of riding in the desert. So far no flats even though I’ve pulled out multiple thorns from the tires. They add weight to the bike, you may not feel as nimble or agile on the bike but I feel I have much better traction.
They can be a bugger to install properly, but worth the extra work and expense in my point of view…UPDATE …well, I did get a flat yesterday. Cactus thorns through the sidewall near the rim. Bring a spare tube just in case…more recent update, got another flat , cactus thorn through the main part of tread. Had to downgrade to 4 stars.

These are mandatory when you live in goat head country. I have not fixed a flat on any bike that I have installed these on.
Wright Adventures –
Installed these on my Ebike for hunting. I often ride on rough terrain and through thick grasses and weed fields off the beaten path. I’ve had no flats with these installed, and do NOT have slime in my tires. They install easy, so long as you follow the instructions and get the proper size.
NOTE: If you feel like they are hard to install, contact Tannus directly and have them look up your batch code. My first set seemed too small, and I found out they were part of a recently found batch of defective inserts. Tannus sent me some new inserts overnight and they fit so much better.

Finally bought a new mountain bike with Maxxis 27.5″ tires and got more flats than I’ve had on all previous bikes combined (like 18 flats in a year)! One day I pulled out 23 goat head stickers and had had enough. The expensive flat tire liners were totally useless even with thick tubes so had to try these and glad I did. Yes they are a little heavy and takes some time to install but haven’t had a single flat since, even after pulling out more goatheads and thorns and also like how they feel when riding. Totally worth the weight and price and they’ve helped me retain my sanity.

After walking out of the trail more than once, I decided to try this product. I had hit a sharp rock for the second time and experienced immediate deflation. After much research, I selected this product. I watched a lot of videos about installation, and wow–there’s a lot of debate on the ways to do this. I got a 5 gallon empty paint bucket and set it on a table. The real trick is I got a small bottle of talcum powder from the “travel” section at target, and liberally powdered everything inside the tire, on the ring, and on the tube. I did my own method of install and it worked! The note here is the special tube it takes–these are not standard sizes–use the tube in the kit. I’ve not been stopped by mean rocks since.
A. Bailey –
This kit is a good value as it provides both the armour and the smaller inner tube necessary for successful mounting. You can’t use the original inner tube as that is too large to use with the armour insert unless you upsize the tire size. Mounting these things is pretty straight forward. I had to trim the armour per directions in Step 1 due to my tire size being the smaller of what is supported by the kit. I used Fiskars Micro-Tip Pruner Non-Stick snips for this and followed the countour identified as needing to be removed. Steps 2 thru 4 are pretty straight forward until you reach step 5b. This is the mounting of the 2nd tire bead onto the rim. Without specialized tools like SHWJ 4PCS Bike Tire levers available in Amazon, this is PAINFUL! The tire levers simplify this step significantly and I highly recommend that you use these or similar tools to help with this step. Otherwise you’re going to get super frustrated just like some of the other reviewers have documented. Without these levers, it took me over 1 hour of frustration, pain in my fingers and scratching my black rims to get one of these installed. With the levers, it took a total of 15 minutes if not less. Don’t install these without tools!
Post install, I inflated to 45 psi and took out bike for a test ride. I can’t really say that things feel different but installation of these gives me piece of mind that I won’t get stuck somewhere with a flat.

Three main points:
1. The tubes
2. The roll-flat-ness
3. The installation
1. The first innertube (of three) popped on initial inflation — just past 10 psi. Both the insert and tube were installed correctly. The second innertube deflated less than a block down the road — the valve came completely off. It was also inserted correctly. Third tube emptied of air a mile into a 2-mile commute.
2. The roll-flat function of these guys is nonexistent — there is no rolling, and the tire is definitely as flat as it would have been without the insert. (I know, because walking miles with a flat tire is exactly why I bought these things…) On this third tube, I had to get off the bike and shuffle it down the sidewalk because the tube came out of the tire and started to wrap itself around my axle, about a block or so after the audible pop. (I had to cut that third tube off, and remove it entirely.)
This mile walk also shredded my rear tire, causing me to have to buy a new one.
3. Installation isn’t really that bad. Essentially cramming a tire inside another tire, then trying to fit a tube in there… is gonna be weird and require some work. I thought/hoped it would be worth it. (It was not.)
I can’t rate the puncture resistance, since the bike never made it far enough to get punctured.
These bad boys look good on paper and in the sweet graphics, but execution is a complete joke. Three innertubes in less than a mile of flat, level pavement is nuts.
The cost of these POSs, the extra cost of buying a new rear tire, and new tubes, has made this experiment VERY not worth it.
In any case, there are two positives. First, I have A LOT of extra innertube rubber to use for patches in the future (though I honestly don’t know if I trust the salvage off these tubes). Second, I’ve got these two sweet pinkish floaty-donut things that might actually make a decent core for wreaths this holiday season…
Seriously, folks, avoid these. Just invest in quality spare tubes.

These are great, after putting them on backed up with Flatout I haven’t had a problem since. They are speed rated though. The bike shakes around 40 mph.

I put the liners into the tires and the next day the one tire was flat. One of the tubes are defective. Contacted company and they sent me 2 new tubes.

Installed these on my Ebike for hunting. I often ride on rough terrain and through thick grasses and weed fields off the beaten path. I’ve had no flats with these installed, and do NOT have slime in my tires. They install easy, so long as you follow the instructions and get the proper size.
NOTE: If you feel like they are hard to install, contact Tannus directly and have them look up your batch code. My first set seemed too small, and I found out they were part of a recently found batch of defective inserts. Tannus sent me some new inserts overnight and they fit so much better.

Contrary to some other comments, I found the installation of the Tannus 26×4 inserts was a breeze and went smoothly. I consider myself an average DIY skilled person, and I didn’t need any extra tools. I simply followed the provided instructions and it took about 10-15 mins per tire, once the rims were removed from the bike, to install and inflate (using an air compressor).
Tip: I found putting a small amount of air into the inner tube (just enough for the tube to have shape) prior to inserting under the Armour made the process easier.
I installed the Tannus Armour inside 1 month old Schwalbe Jumbo Jim Addix Speedgrip tires for my e-bike. These hard to find Schwalbe tires are fast rolling, lightweight and relatively thin, so I wanted to have the extra protection since I frequently venture into isolated areas, as well as occasional highway trips into the city that is 45kms away.
I run the tires at a higher psi (28-30) when I travel on longer trips on pavement, and I noticed there is little difference in the ride with the inserts. When I trail ride I usually run at around 15 psi depending on the conditions, and noticed that the ride is a little firmer than before, but the traction and handing is pretty much the same. I have yet to try them in mud or snow at an ever lower psi (8) and will have to wait until the fall/winter.
It’s too early to speak of the puncture protection, but with my new Schwalbe “snakeskin” tires being so thin, I definitely have a much higher level of confidence in avoiding flats. I will update this review should anything change.

After getting several flats on my hunting ebike that left me pushing my bike, I decided to spend the money on these inserts. They are expensive, but if they prevent flats will pay for themselves in the long run. So far they have performed as advertised, have made it through their first season without any flats. I traverse some pretty rough terrain with honey locust and cactus. Install was similar to changing a inner tube, not a difficult job. If they last 3 or 4 seasons without a flat, I will consider them worth the cost.

Inserts are a pain in the back side to install. The tubes that came with the kit are extremely poor quality! Imagine after going through all the hassle of installing them only to find the tire flat after sitting over night. One of the tubes had a small pinhole where rubber is molded together. I tried patching but patch wouldn’t hold.

I had this installed at a reputable bike shop, and the inner tube was flat after 1km of riding. Was the inner tube just that poor quality?? It’ll be such a pain to get the tire armour out and deal with an amazon return, so I’m stuck going back to the bike shop and having them get a new inner tube. Very disappointed.
Mazdafun –
No flats since I’ve installed my set!
They also seem to soften impacts slightly, and I don’t think it’s all due to being able to ride with pressure 5-10psi lower than usual.
They take a lot of fiddling to install and be sure they’re centered.
The valve stems also barely come through my double-walled rims. It was quite difficult to get enough purchase for the pump to inflate them. However, I was able to find a nice set of extension valves that solves the issue.

J’ai pas eu de difficultés à les installer, j’ espère que ça vas être efficace pour ne pas avoir de crevaisons.

These inserts are the best! Makes fat tire issues go away. I ride in the toughest terrain popped many tubes and tires before finding these. Every bikes gets them now! Thank you!

If you go far from home, you should get these so you don’t get stranded/have to walk miles home due to a puncture. A piece of bone on a trail popped my tire. Never again! It does make peddling a bit harder and reduce your range a bit if you are using an ebike but not by too much. The trade off is worth it.

Things to know. Have a tire lever tool to get off your tire to start the process. Have a valve stem remover to control your inner tube and electric air pump that can read psi. Have decent sharp scissors as you will likely have to trim it. The process is straight forward. If you try install it right out of the box it is far too big so you will likely need to trim it first. I am installing 26×3.0/4.0 tannus armor. You can see the picture of what it looks trimmed vs not trimmed. The tannus armour should stick out only a little out of your tire. Put in the armour first and then put one side of the tire and armour inside of the ride. Use the ground as your leverage to the rim down and push the tire and armour down to snug into the rim. If the other side is having a hard time to go down. Make sure release all the air by removing the the inner tube valve stem and then push down on all your tires to remove the air and it should go in super easy. Took about 45 minutes to install both.

They were a little difficult to install but now that they are in, I haven’t had any flats for the last several months. Before, I would get a flat about once of month or more. Initially, I felt like it made my ride feel stiffer but now that they are broken in, it feels almost cushioned. I didn’t notice any weight difference but I am using an ebike.
I feel like they are a bit expensive but not having to repair tire flats has been worth it. I would recommend it if you can afford it.

After my 6th flat tire on my ebike in 4 months I went ahead and decided to give these a try. Small pieces of wire and a piece of glass were always the culprit.
Now I have the Tannus paired with HEB AllScape heavy duty tires. Hoping it makes me closer to bullet proof.
Do yourself a favor and make sure you have a good tire lever set. Will make your life a lot easier. It’s not a hard install if you’ve replaced a tire and tube before, but does take some extra time given how much you’re stuffing into the tire and then mounting on the rim. Haven’t had an opportunity to ride on it yet.
Adding these will also make swapping out a tube much harder but if I get less flats I will consider it a fair trade.

Tire removal on an e-bike is not as easy as it is on a regular bike, because of the motor(s) and wiring. It is even less fun when you have equipped it with accessories such as saddle bags and the like. And, at my elder age, getting on my knees at odd places roadside to effect a repair of a tube is no fun even if the front wheel has no motor encumberments. Especially so, as I ride in all weather. In the first six months of ownership of my first e-bike, I had ten sudden flats and two slow leaks to contend with, in each case very small items, such as a carpenter’s staple, or a brad-sized nail, all hard so see ahead on the pavement, while at speed. I tried the goop in a spray can someone offered, and it not only did not help noticeably, it made a considerable mess of things. So, as I had a credit at the place I had bought the bike, I bought a set of these Tannus Armour inserts from them, and once installed at the next flat, that same bike went another 3000+ miles with no flats, over the next two and a half years. I do also ride off-road, btw, where sharp rocks and broken bottles are often hazards harder to spot. So consider all these things when comparing the price against the value of your tires and enjoyability of your bike.
So I bought another set with my new e-bike recently purchased through Amazon… with two motors. I’ve not installed them, and won’t, until the first flat. One reason I have saddle bags, is to carry them with me, along with an electric air pump also bought from Amazon. Now, while out and about on my old bike with the inserts, I did use that pump several times, stopping to help other bikes without inserts fix their flats. I evangelized the idea of inserts to those riders.
Likes: no more flats = no more sore knees, lost time and effort and general unhappiness and inconvenience, all replaced instead with a learned confidence that it would have to be something more easily seen ahead on the road if I was to have a flat: something more easily avoided. You fell more like a Destroyer captain who knows the depth of the water with the certainty of sonar, chugging at cruise along the coastline looking for submarines. Increased the resale value of the old bike and made the new owner very happy at the notion. Comes with special tubes especially made to work best without pinching or causing unequal tension on the tube’s surface due the displacement of air within the tire by the insert. Increases the resale value of the bike (I’m no physicist, and do not play one on TV, but that’s my take). Compared against the value of my time and my knees, I look at it as costing $40 a year or every thousand miles, whichever comes first — if I upgrade my bike every four years. Make that $30, given the increased resale value of the old bike. And, you can always test that, offering a lower price if you remove them inserts and move them to your new bike, cutting the cost in half for the next four years. Do the math: it computes as a good investment and real-world value.
DON’T FORGET to choose which valve stem style you prefer – another feature/benefit – but you don’t want to accidentally get the wrong one.
Dislikes: may or may not apply to your particular bike/tires. On my first bike, I had to trim off portions of the insert that would fit agains the sidewalls, protruding above the tire’s rims. Does cut easily with scissors, as it is very thin, there, and flexible. There is no easy way to do that uniformly and accurately, and evenly on each side of the tire, such that you don’t risk an out of balance tire (don’t know if that’s actually possible: just a worry in my mind), or pinching of the tube at the rim’s seal (also in my mind, no doubt). It’s just a step I wish could have been avoided.
CONCLUSION: a must have for sane and safe, enjoyable biking. A SMART BIKE MFG OR STORE would always offer the choice of pre-installed inserts, or not, to save installation woes and waiting for that first flat because of those woes.

About five years back, I finally threw in the towel on tubeless. I’m not a racer looking to save 100 grams… I just want to be able to ride all day without having to spend hours fixing flats (often with a tube anyway) or worrying about whether I have the air pressure too low to keep the bead seated or protect a rim when I go over a rock. Eventually, I just reverted to putting the tire sealant into the inevitable replacement tubes. But that still leaves a potential for pinch flats and rim damage. This solves both issues at once.
My kit included a good set of Kenda 26 by 1.50-1.75 tubes. The liners and tubes were easy to install into a 26 by 240 MTB tire, and mounting the tire really wasn’t any more difficult than usual. Some tire sizes require trimming of the liner’s sides (mine didn’t), but there’s actually a line on them that shows exactly where to cut. And unlike most tubeless rim-protection pads, they shouldn’t be difficult to field-service should a flat somehow happen.
So far, I’ve had these out twice on my old FSB for a total of about 12-miles of asphalt and around 30/35-miles of mixed dirt road, single track, and rock-strewn fire-road. An interesting observation on asphalt is that with 35-pounds in them, the knobby tires are pleasantly low rolling resistance. In the dirt, the advice to drop the air pressure by about five pounds from what one usually runs seems accurate. I usually keep about 22 to 25 pounds in the dirt. But running about 5-pounds less seems to have about the same feel. They also allow the confidence to air way down, should you want.
I know these aren’t the trendy tubeless kludges everyone is currently fighting to install (field service!?). But I’m also not a compensated racer promoting the latest trends. I’m simply happy enough with these that I may order another set to try on my gravel bike’s 700 by 42 tires… which have also been switched back to tubes.
