Mr. Tuffy Bicycle Tire Liner

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.

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!

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.

I've been a "serious" cyclist for more than forty years (60 - 100+ miles per week... not counting commuting to work, thirty miles round-trip). In 1985, I became a dedicated mountainbiker (10 - 15+ hours per week in the southern and central California mountains) while continuing to commute to work on a road bike. Got my first Mr Tuffys in '88 or '89... and they changed everything. Like Sean Lee's New Mexico (see his May 16th, 2010 review), southern California also has "Goat-Head" thorns. For those who aren't familiar... they're a 1/4" to 3/8" diameter seed-pod that looks exactly like a beige-colored miniature spike-ball, and they're as hard as steel. Riding anywhere that these things exist causes you to very rapidly become an expert at tube-patching and fast tube-replacement. Incredibly... once I started using Mr. Tuffys, I went from getting sometimes two or three flats a week, to almost NONE. Needless to say, I've been using them ever since then... with only one exception. Sometime last year, I replaced the old, worn-out 1.5-inch road tires on my 28-year-old Ibis mountainbike (I've been using it as a road bike for a good while, now), and put on a new set of one-inch road tires... so I decided to replace the wider Tuffys that were in the 1.5s with narrower ones, as well. Since I now live out in "the sticks", the three "nearby" bike shops only had non-Tuffys for sale, but I thought "what the heck... how bad could they be?", so instead of ordering some Mr. Tuffys online, I bought the off-brand ones, and put them in the new tires. As things turned out, though, I ended up riding off-road on my newer mountainbike most of the time since then, so I spent almost no time at all on the Ibis this past year... until about six weeks ago, when I started riding regularly on the local roads with a neighbor who is new to cycling. Well.... Last week, we were ten miles down a back-country road, when my back tire went flat. Looking at the tire, I quickly found a single goat-head spike embedded almost dead-center in the tread -- right where the tire-liner is theoretically thickest and strongest. Imagine my shock and amazement, when I pulled the tube from the tire, only to discover that the one year-old tire-liner had almost completely decomposed, and had bonded its fragmented self to the innertube! Upon inspecting the front tire once I got back home, I discovered that the same thing had occurred to its liner as well. I spent the following day calling every single bike shop within a FIFTY-MILE radius of my home (maybe twenty shops, all told), trying to find a pair of Mr. Tuffys. Not ONE of the shops carried them. The only ones that any of them carried, were the generic off-brand ones, like the ones that had just dissolved. My assumption is that these shops carry the inferior, generic liners because they can get them much more cheaply than Mr.Tuffys. And since bike shops make the major portion of their profits from sales of parts, it's pretty easy to see their "logic". But... while I definitely prefer to support my local shops... in this case, I won't be doing so. Waiting a week for the Mr.Tuffys to get to me (they just arrived) has been a pain. But I'd far rather be safe, than sorry. Like I said... FORGET the other brands.

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.
