These hoses work great. I installed one (different size) in my car almost 5 years ago. In the 5 years that I've had a tube in it, I no longer had to put air in a tire every time I used it, instead of having to put air in it. I was so impressed that I bought another one for the rear tire on my garden tractor (different size). This tire has only been on the tractor for 3 years but I have never added air to it. I later added one to the front tire (that size) of the same garden tractor and got similar results. So I added Slime brand inner tubes to three tires and I haven't had to add air to any of the tires since. Good product. The only complaint I have is that they cost a little more than a regular tube but they work so well it's worth it.
