Inner Tube Protecting, Bicycle Tire Liners Pair - Stop Flats for BMX Bikes Using Green 20 x 2.0-2.125” Bike Tires and Tubes with Hard Durometer Center Strip. (2 Liners)

They fit and the tubes still hold air

This product is a tube saver keeping all the haters out including thorns it’s pokey friends.

very "cheap". seemed more like crumbly candle wax than a plastic liner. was able to punch a small test screw though the material with very little effort in multiple areas. returning this useless product. going back to my tried and true Mr Tuffy.

This product on multiple occasions has completely disintegrated, leaving debris inside the tires the punctured the tubes! I don’t understand what’s happening. I’m only ever riding on pavement at an average speed of 21mph. I’ve had 6 tubes get punctured before I figured out it was the Thorn Buster causing the damage. 6!!!

Installed in a high wheel lawn mower that runs in a vine with thorns. Solved the frequent flat tire issue.

These liners did not protect my inner tube on my walker. I have a walker that I use outside. It has 13 inch wheels with pneumatic tires. I live out in the country and have a lot of grass burrs. I thought these liners would help to prevent flats from the grass burrs. The liners did not help at all. Burrs still punctured the tubes. I just ended up getting solid rubber tires. Did not work for me.

This is the 2nd time I have ordered this product I don't know why they can't get it right. I have talked to the bicycle mechanic and he said this is too narrow for my tire it will not protect the bicycle.

Don’t waste your money. Does not work on goat heads here in west Texas.
