Mr. Tuffy Tire Liner
Mr. Tuffy tire liner helps protect your bike tires from punctures, making your bike rides worry-free.
I ride 40+ miles daily & since installing these liners I haven't had a flat in over 8,000 miles now! I use to get flats from sand spurs (x2 flats in one ride), road debris, glass, etc. I really lke these liners, no complaints here!!! ;-)
Best protective tire liner! I have use it around 7 years, and it is an excellent product, if you want to complete your ride safe and free of inconvenience this is the right option.
I'm not too pleased with this product. First problem is a major problem and that is keeping the liner in exactly the right place while you insert the tube and fill the tube up, then have to deal with that hassle all over again when you get a flat. Second problem is this liner is made of some sort of plastic and I've found stuff penetrated this fairly easily, it seems to work well against stuff like wire and glass, but it failed against goat heads and small tacks. Third problem is you can't use an ultralight to medium weight tube with this liner because the overlapping edge of the liner will after time rub a hole into the tube, I did find a sort of a fix and that is to sand the edge that lays against the tube down to almost a paper thin thickness, then it will work in medium weight tubes. The good news is this liner is reusable whereas any stick on liner is not, but the frustrations I had with it between keeping the liner in place and failure to prevent the type of flats I was getting just doesn't make it worth while. I have since found a great liner that is far lighter and sticks to the inside of the tire and it stops goat heads and anything else I've encountered.
Awesome tire liner. Ordered these with my new tires and haven't had any flats yet on my road bike. Extra protection for a good price.
Great liner I haven't run in to any problems, only thing is I wish it would cover more of the sidewall.
