Mr. Tuffy Bicycle Tire Liner

I've installed these on four of the family bicycles and am impressed by the results. Now, to be honest, I didn't get a lot of flats previously. But any flat is a P.I.T.A. when you're looking to finish your ride or pull out your bike to discover a tire went flat from sharp glass or metal pin overnight.Thus far, I've installed onto my wife's hybrid using 700x35 Schwalbe's, an old Raleigh X-bike using 26x2" specialized, another old Nishiki Hybrid running panaracer 26x2.1" and my roadie running Continental Ultra-Sport 700x25's.These work very well for preventing common causes of flats such as glass shards, wire scraps, etc. But they won't prevent ALL flats. For best results, inspect all the tires for any debris on the inside, use a fabric based rim liner and ensuring the tubes have no issues.They ARE a bit of a challenge to install. Personally, I:1. Install the tube into the tire with just a little air.2. Install one side of the tire/tube combo onto the rim.3. Slide the liner between the tube and tire with the wheel lying flat (not upright)4. Start the liner on the opposite side of the tube valve and work around until it overlaps.5. Install the second side of the tire onto the rim and inflate with a little more air and check the seal.6. Fill the tire to the recommended pressure and double check it's seated properly all around.After the installation I haven't experienced flats from road debris.

I have used these for years. They are an additional quality liner that helps prevent flat tires.Last week I road off the road and went over patches of goat head stickers. I got probably 10-15 goat heads on each tire.I stopped and pulled them all out before riding on the road again. I was able to ride home and the next day one of my tires was flat. A check of the tire and tube showed the goat head penetrated on the side of the tire where there was no liner. Anyway had I not had these, I would have gotten two flat tires for sure.Great product that helps prevent flats; I highly recommend!

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!

-> Tires are more and more offered (when available) as solidly built (K-shield…) but an extra layer does not hurt.(+)EASY to install, even for a beginner. WELL-DESIGNED in 2 layers integrated, one in colored PVC (FLEXIBLE, with NON-CUTTING or brittle edges like some competitive products) and another seeming more rubber in the center, it seems to ensure that the product stays in place while ensuring a soft contact with the tube. At touch, the MATERIAL seems of a good quality, neither too hard not too soft.(-)- There is NO THIN STICKER that would guarantee that the product stays in place (well in the middle) so you have to mount it in a horizontal position and hope everything fine when is time of the vertical position (most of the time, for final assembly with the wheel). Some say that the tube could push the guard in a perfect mid, it may be true, but nothing says it and everything seems fine in the end.- The PRICE of the product is certainly still quite high, at the beginning of 2023, but after 4 tube replacements (10-15$ USD each) in 2022 I hope that it will save me some money and trouble too.Mention:The GOLD is close to the PURPLE (in size) but it seems that the latter would be a little larger (especially with a 700 x 35-38) to slightly cover the sides.QUALITY-PRICE ratio; (FOR NOW) GOOD ! Remains to be seen with time. * Various other products exist, but several seem to have only a lied impact when faced with different sharp objects. By carefully analyzing the reviews of other products, it seems that some even end up being brittle or even creating punctures by themselves with sharp edges or ending up causing wear on the tube. I haven't seen any such comments on Mr. Tuffy's seller page.I reserve the right to update this comment if there is a problem.Hoping that this little unbiased review will help you.

con estas cosas desde que se las puse, jamas he ponchado, son magicos, altamente recomendados

Installation was quite easy, so far no flats, but I've been using tires with the liner for a week or so. I did trim the liner, but left it still overlapping a little bit.
