## Description

desertcart.com : Fat Bike Tire Liner, Bicycle Tube Flat Protector Compatible with 20"/24"/26"/27.5/29" (29x4-5) : Sports & Outdoors

Review: Very Tough. - This thing is tough. I cut a swatch out and tried to press a nail through. I had a very hard time even twisting it. the installation is a bit tricky. deflate the tire but not all the way. it should have a quarter inch between the tire and tube. Warm the lining up slightly. this will help with sliding it in. You can even use some baby powder inside the wheel if you are having a hard time sliding it in. It will want to twist on you. just keep feeding it slightly about 1/4 of the way around the tire. go back and tuck the first section inside. keep preparing until you have it all the way slid into the tire.
Review: Great product!! - Very good product it works very well, but it is definitely not a one-man job. I had to buy some glue to glue it to the inside of the tire then I put another protector that is called. Tannus Armour Tire Insert Then I put the tire back on the rim then I put the tube in install the rest of the way pumped it up and have not had a flat tire since hopefully this is helped somebody
