Fat Bike Tire Liner, Bicycle Tube Flat Protector Compatible with 20"/24"/26"/27.5/29"

This thing is tough. I cut a swatch out and tried to press a nail through. I had a very hard time even twisting it. the installation is a bit tricky. deflate the tire but not all the way. it should have a quarter inch between the tire and tube. Warm the lining up slightly. this will help with sliding it in. You can even use some baby powder inside the wheel if you are having a hard time sliding it in. It will want to twist on you. just keep feeding it slightly about 1/4 of the way around the tire. go back and tuck the first section inside. keep preparing until you have it all the way slid into the tire.

Very good product it works very well, but it is definitely not a one-man job. I had to buy some glue to glue it to the inside of the tire then I put another protector that is called. Tannus Armour Tire Insert Then I put the tire back on the rim then I put the tube in install the rest of the way pumped it up and have not had a flat tire since hopefully this is helped somebody

Doesn't stay in place. It should have adhesive on it so installation can be easier

Installing this was a bit difficult. It was hard to keep lined up straight while installing. I've never used or needed a puncture liner on thinner tires, but I kept getting punctures with the fat 4" tires. After my 5th puncture i installed this and I haven't had any new punctures, so far. After cutting to length with about a 1.5" overlap, I also decided to round the corners, since it looked like the pointed corner would pinch into the tube and cause issues later. It was a pain to keep this thing properly lined up. I had to inflate the tire to seat it, but it would wiggle off during inflation, and I'd had to keep deflating it to adjust it. Eventually, I got it mostly in place with less wobble. The edges would wrinkle up because the roll comes flat and pulling into the curve of the tire. Be prepared to spend a lot of time trying to install this. It's not an easy install since it slips around in the tire while you attempt to inflate it. You have to keep adjusting it during inflation.

Literally impossible to make work, don't waste your money! I want to jump off a bridge after trying to make these fit.

Lots of blackberry bushes where I live and when the road crews cut them they throw the thorns everywhere all over the road. I was getting flat tires until I got these. I highly recommend these along with an upgraded “puncture” proof tire.

3/5 because I did get a flat in one of my tires. Not a nail, not a screw, not a thorn, but on gravel. I'm really not even sure how that's possible with puncture resistant liners.

Update..make sure you round the corners on the liners they will pop your innertubes i had 3 flat tires in 2 weeks and could not figure out why.i noticed it was always about half way up the side of tube same spot all 3 times.finally i notice it was right where the liners slightly overlapped and the pointy edge had poked a hole in tube.trimmed the edges and been flat free ever since.. Very easy to install and gives you piece of mind.made of very tough material.5 of 5 for me. a few things you need to know.first install with the curl of material down this will keep it from rolling up as you go around inside of tire.then insert innertube with enough air to hold liner in place (just enough to hold shape) then install on rim and "do not" overlap liner more than an inch or so especially with a ebike (because of high speed) as it will throw off the balance of your tire.found that last one out the hard way.

Buona vestibilità per bici elettrica 20 fat

La verdad que estos protectores vienen bien para los abrojos, aportan resistencia a las cubiertas y la instalación es sencilla, no he notado ninguna diferencia a la hora de rodar pero si es cierto que, en este tiempo no he pinchado. La mejor forma de agradecer el esfuerzo por ayudarte a decidir es dándole a útil en esta reseña, gracias!!

Difícil de instalar, pero creo que son buenos, no me he vuelto a pinchar

Very happy with my purchase. Install can be a bit tricky but I found if you let air out it helps and if it is still tricky let more air out easy peasy. You must trim to proper wheel size if not the wheel will be unbalanced. With the piece that I trimmed off I tried to drive my Cutters through the center I found that I could not very impressed I think this will work much lighter than slime. Should improve my mileage and top speed
