Mr. Tuffy Bicycle Tire Liner

I use the on two 20” wheel bikes. Each has a combination of tpu and rubber tubes. They are 1.95” fold style tires. They installed with zero issues. Since there was about a foot overlap, I trimmed them to be more like 2” overlap. RECOMMENDATION: Don’t use with already puncture resistant tubes as there might be too much material between the tube and the road causing a bulbous effect. Also if getting new tires for these get thin foldable kinds. The problem is with wire bead types and ones already puncture resistant, adding these means there is going to be LOT of material in there causing the bulbous feel, and very hard to get the tire on/off. These are installed on just very thin foldable tires and the tire went on very easily and the road feel is even better than without - feels more stable and better dampening. Nothing has penetrated them in one full year.

It is easy to use. And protect my tire!

Haven't got a flat since I installed them. Probably would be easier to install and keep in place if they had an adhesive backing.

I'm 49 and have been using Mr. Tuffy since I was riding Skyway BMX bikes back in the early 80s. They're simply great and easy to use and easy to install. And they don't breakdown either. It's a one-time purchase. About the only thing you need to do is remove them, wipe them clean anytime you swap tires and/or tubes. As with any technology and materials, I'm sure Mr. Tuffy is slightly thinner, lighter but stronger since the ones I first used in my BMX bike 35+ years ago. For moms and dads, I strongly look into buying either thorn-resistance tubes or Mr. Tuffy tire liners for your kids bikes....especially once your kids reach 8-10 years old and start exploring farther and farther on their bikes (and start heading off the pavement). These will get many more miles, days and weeks and months between possible flats and punctures. When you're dealing with thin rubber inflatable bicycle tubes (and everything you can do on a bicycle), nothing is going to be absolutely 100% proof, but putting a little protection between the tire and tube (as well as some additional protection between the tube and rim) will keep you and your kids rolling alot longer. My boys have 24" bikes. I purchased the blue color (based on width of tire). The width is perfect but the blue 26" size was obviously too long. I simply install to make sure the tire liner is fully against the inner tire wall, then trim/cut the tire liner so that there is only about 1-2" of overlap. Easy but always measure 2-3x and cut once!

I've never had a flat tire on any bike that I've installed these on. Is there empirical data that shows that these slow you down slightly? Probably, but maintaining the highest possible cruising speed isn't my priority. I have them installed on my daily driver, commuter, casual ride with friends bike. It's about the experience of being outside and enjoying the ride, not worrying about if I'm riding 1/10 mph slower because of my tire liners. Would I use tire liners if I was riding the lightest possible carbon fiber road bike on a velodrome? Of course not. But I'm not, so I use them.

The best thing you can put in your tires. I have been running these for months now and I have not gotten a pop tire, even though I've ran over most likely a whole lot of glass. These are not a want. These are a requirement. If you need a bike and have a bike and if you need to change your tires I suggest you put these on I'm not even a joke on this as well. Ride quality didn't change, but being able to ride over glass and not have. My tires popped wonderful. My tires have had the exact same air pressure. In them, since I filled them last time, which was when I installed those. So yeah, I would get these 100% Mr. Tuffy tireliner is literally the best thing. If I could to meet the guy who invented this, I don't honestly shake his hand he is a genius

Rebuilt some classic spinergy rev x clinchers, now they’re basically puncture-proof. So far I’ve ridden about 200 miles, commuting on crusty roads where I usually get flats almost every time. Paired with my Pasela hybrid tires I’m very happy.

Did not work for me . Instructions followed as per package. Installed in both tires and both tires were punctured multiple times . I will be trying the slime tires instead.
