Bike Tyre Liner, Anti-puncture Proof Belt Tyre Tape Boom, Bicycle Tube Flat Protector Compatible with 12" 16" 18" 20" 24" 26" 27.5" 29"

No punctures so far, not sure if by luck or the liners are working. They are very sturdy so can't see much penetrating them. Installed these as an alternative to slime

These are pretty good, but be aware they do add weight to the tyre.

Tyre must be quite rigid to fit the puncture resistant strip. Not easy at all if tyre is floppy. Too early to say if reduces puncture risk. The green one is wide enough for a 23 or 25. Brown for 28 or more.

One month a nail I think punchererd oner, couldn't find object but found puncture hole 🧐

Nice and thick so it would definitely work as puncture resistant layer, however it does add thickness to the tyre so be very careful as you might run out of space inside the tyre and may not fit the inner tube peoperly which could cause a puncture.

I thought I’d try these as I do a fair bit of mountain biking which often takes me down trails lined with hawthorn which, after cutting season, causes havoc for cyclists.150 miles later, over half of which were on road, I get a puncture despite having these fitted. Sure enough it’s Hawthorne. I remove the spike from the tyre and while doing so thought I’d try the Hawthorne directly into the ‘protection’ belt. Guess what… it went straight through it with minimal effort. Didn’t even snap the point !Now maybe I was just unlucky. Maybe I inadvertently placed my rear wheel directly over the strongest and toughest Hawthorne spike that has ever been grown and, just maybe, that spike had an amazing superpower that told it exactly where the weak spot in my armour was before it carefully positioned itself at just the right angle and penetrated my protection, who knows ?My guess is they’re just not up to it.If you’re nipping down the shop on your bike every other day then these might help you a little.If like me, you take your riding seriously and want to bomb through the trails not having to worry about punctures then I’d look elsewhere. These just don’t do it.

I was a bit apprehensive because I had been told if you don't put in the tyre correctly then it could pinch and puncture the inner tubeBut I was able to install correctly I used to get a puncture on at least a weekly basis but in the month I've this installed this the only puncture I got was a knife blade and nothing else so very happy

Such an amazing money saver, really tough material, easy to fit
