They were pretty easy to install. But only a year later, neither one nor the other is holding its breath. I bought inner tubes to use in my trailer's tubeless wheels and tires because the tires no longer hold air on their own. I was so excited to put them on last year and didn't have to air the wheels out every time I wanted to use the wagon. But unfortunately I'm back in the same place. They lick in just a couple of hours. It's just hard to find quality products these days. Cheap - cheap - cheap! Anyone remember when your bike tires held air for years? The company was good. Product. not as much. TO EDIT. 23rd July 2018 Decided to remove and examine the hoses to understand why they are leaking. The hoses just leaked through the rubber in many places. It looks like thin sections of pipe. But no glitches.
