Review: Great price great product - I put these tubes on myself.. really good product
Review: Buys You Time - No matter how careful, it's inevitable that you will eventually bike over a nail or other sharp object that will puncture your tires and tubes. How well these tubes seal is dependent on the size of the hole which obviously varies depending on what you ran over. The hope is that when you do run over something, the hole left behind is small enough that the sealant can just spray out and plug it without losing much air. Sometimes that can happen. However, my experience and expectations with these self sealing tubes is that they buy you time from the moment of piercing to when you have to repair your tire. That may seem like a ding against the product since you most likely still have to repair the damage, until you realize that a regular tube with no sealant would go flat immediately. A flat would require immediate repair on the spot, or just totally take the bike out of commission. So the value I see in these self sealing tubes and why I'm rating 5 stars is that they still allow you to bike and get to a proper location where you can do a repair. I would still recommend having a hand pump or some other means to put air back in your tubes while on the road. As I said, the sealant buys you time and allows the tires to hold some air once punctured. As a "positive" bonus, when an object pierces the tire and tube, it becomes extremely obvious where the hole is since you will see a bunch of foam spray and leak from the tire. So when you do finally go in and make the repair, it makes inspection of the tube and tire much easier.

### ⭐⭐⭐⭐⭐ they work great
*by S***S on August 12, 2026*

these were pretty easy to deal with, i got a mountain bike with presta valves and drilled them out and replaced them with these tubes with schrader valves, it makes everything easier and its the same valve a car uses to you can use most air pumps without an adapter. if you air down your tires they are filled with goop so just be aware that that is a thing.
