Armour Tire Inserts, 2 No Flat Bicycle Tire Liners with 2 Tubes, Puncture Proof Bicycle Tube Protectors, Stops Flats Compatible with E-Bikes, Mountain Bikes and More

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.

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.

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.

Three main points:1. The tubes2. The roll-flat-ness3. The installation1. 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.

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.

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.

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 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.

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.

Con una anchura de 50mm, es imposible montarlas aún en llanta 67 (26x2.35) 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.

Satisfaction. Recommended no more flat

Contrary to some other comments, I found the installation of the Tannus 26x4 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.

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.
