Stop Flats2 BMX Bicycle Tire Liner

Review edited to change stars: I had initially rated as 1 star to draw attention to this review because I felt it was important for people to be aware of sizing issues (I got the wrong size), but since I am currently the only reviewer of this product, I felt that my "artificial" 1 star review could negatively affect sales of a product that was good in every way except for the amazon description. Several months since installing these, I have only had two flats, and both were a result of running over really large shards of metal (I was getting flats about every two to three weeks before I installed these). Unedited initial review follows:While I have no problem with this product (I've only used it once so far, but it seems to work as advertised) there is no size chart on amazon and these are not universally sized. The color refers to the size tire it fits with. If you get a set that is made for tires with a smaller circumference than the tire you have, it will not cover the whole tire. Width is probably less critical than circumference/length, but should also be taken into consideration.(Road bikes)Orange: 27'x1' 700c x 23-25Red: 27 x 1.25"-1.125" 700c x 28-35Blue: 26" x 1 3/8", 24" x 1 3/8", 700c x 38-40Gold: 700c x 32-41(bmx bikes)Yellow: 20" x 1.5-2"Green: 20" x 2.125"Mountain bikes (26 inch tires)Brown: 26" x 2-2.125"Silver: 26" x 1.5-1.95"Sage: 26" x 2.25-2.5"Mountain bikes (29ers)Tan: 29" x 2-2.125"Lavender: 29" x 2.25-2.5"Other than the sizing issue, they were easy to install (if you can change a tube you will have no trouble putting these in).

my kid's bike back tire was going flat once in a week.. he is a beginner with training wheels and often run the bike on pine cones for pleasure.. checked for suggestions in various forums and tried this.. to my surprise.. there is no flat tire after installing this.. Remember you need to cut down the length to accommodate to your wheel size.. but works truly great!

My Daughter-in-Law loves to take my granddaughter for walks in the state park close to our home. Unfortunately she had a flat tire on her first time out. We ordered the tire liners for the baby carriage tires even though they are designed for a bike. The tire size was the same as a bike tire. The first tire the liner was very easily installed. The second tire was much more difficult to get into place. Over all we are very pleased. No more flats. They really do work.

It's too soon to rate this product since we aren't in riding weather yet but the quality & installation were very good. It seems like a very durable product that would be hard to penetrate and the edges are tapered & polished smooth. I installed so the overlap rolls over obstacles instead of into them possible saving repeated hits to my innertube. I'll follow up with an update in a few months.

Great insurance against flats. Since installing these, I have never had another flat. I ride good tires, thorn proof tubes and these. Weight ?? Who cares, I'm not a spandex wearing, weight weenie. I like to RIDE, not repair tubes.

We've had zero flats in our wheelbarrow tires since installing these liners. We live with prickly pear cactus in abundance, and so far, so good. Not terribly easy to get in the tire, but worth the trouble.

My kids are always coming to me with flat tires because of the goat heads in our yard. I have installed these in all their bikes and so far we have yet to have any more flats. Definitely a must have to prevent tube punctures!

Put them in mountain bike cargo trailer tires this time - adds some weight but super protection.
