Mr. Tuffy Tire Liner 26" x 2.5" Brown

I have been using these liners for years so I know they work with regard to light puncture prevention such as thorns and sand spurs. Won't stop big stuff like nails and screws or large pieces of glass.

1st thing to note. These are the thin/lightweight version, not the regular thickness ones. 2nd thing to know, they are only 1.5" wide.Since I installed them, I got 3 flat tires. 3 of them were at near the corners of the tire, so they all missed the liner (goatheads) so this liner did not help, not wide enough, and not sure if it would have stopped the goatheads even if they hit in the middle of the tire. The 4th flat was a small metal nail and it pierced right through the tire and Mr. Tuffy liner without a problem, see pictures. Not so tuff after all. Basically I wasted my money and time, still waiting to see it prevent a flat...Will update if it stops a goathead, but I don't think it will honestly.

These work great for those areas with a high amount of goatheads or thorn type sandburrs that will punctur the innertube qiuckly. I use these on all of my bike tires for that added protection. Great Product!!!

Okay, I thought these would be great. My bike tech is super experienced and rounded the ends and installed them nicely. One week later? A flat. Had it fixed, but the guy who fixed it (a kid at a shop near where I work) just said "I dunno" when I asked what caused the flat. One week later, flat #2. Took it to back to my super experienced bike tech. He showed me how the edge of the Mr. Tuffy (not the part he had rounded, but the flat long edge) had cut the tube. Can you believe that? These are supposed to PROTECT, not CAUSE a flat. He said that he sees this from time to time, and thinks it might be some kind of chemical reaction between the Mr. Tuffy and some tubes, not all tubes, and not consistently across tube brands. Waste of money both for purchasing them and waste of my bike tech's time in installing them. And, yeah, then there's the $$$$ spent to repair the flats. I have an ebike, so rear tire flats are a bit spendy to get fixed. Goodbye, Mr. Tuffy!

Not too difficult to install considering you have to open up the tire to slip the liner inside. So far I have been removing several goat heads from my tires after each ride with no punctures. So far so good!

While the claim that is 'stops' flats may be a little over the top, it certainly helps prevent them.Use reinforced tires, tire liners and Slime, and you stand a chance against goat heads, broken glass, carelessly discarded nails and screws, etc. etc. etc.

I use this liner with antipunciture protected tires, slimed downhill tubes and velox rim tape. So far so good, no flats. And when I got a screw in my tire, still made made it home 3miles away.

Relatively easy to install; lets hope they work as advertised. If not I'll update...
