The "no more flats" is certainly not true. But at the same time, they have worked well for me in about five thousand miles of riding. Here is my experience: They do get punctures the same way as regular tubes, but if you are moving along the puncture will partially seal. I also use very tough tires (Continental Gatorskin). You can see the green stuff ooze out at the site of the puncture before "sealing". On a recent occasion, my tire went completely flat at a very inconvenient location. I pumped it up instead of trying to replace the tube which I carry (not the slime type). I pumped and spun the tire as fast as possible; repeating several times. This got it up to maybe 60 psi which was good enough to ride back to my car some 30 miles away. When I got there, the tire was still rigid enough to continue riding on. But at home after a few days, the tire was down fairly low, although not completely flat. I replaced it at home, which is a lot easier than doing it on the road, especially since I find it difficult to take the tire off the rim due to arthritis in one of my hands. Another problem I encountered is that the green goo clogs the valve making it hard to inflate the tire when it is low. I take care of pressure before leaving home. I found that if you let out some air the green goo is flushed out of the valve. Then you can re-inflate the tire more easily. I would not recommend risking inflating the tire after you have arrived at your starting destination. Let me say a little more about the flat tire problems on road bikes. I found that the aforementioned Gatorskin tires take care of most of the puncture problems. They resist all the big stuff like small nails and glass shards. What gets through them is fine wiry debris that is left from shards of shredded steel belted tires that are on the road side. In almost all my flats, that's what I found. These wires get through the kevlar and cannot be seen or removed from the outside. Hence requiring a removal of the tube before the tire can be cleared and restored. No tube will seal itself permanently in this situation. So, if you use the puncture resistant tires, these tubes will essentially get you home, but you still have to replace them. For me, that is worth it, so I am giving it 5 stars. I know riders who change tubes out in 5 minutes - for them it is not worth it because these tubes are heavy and expensive. Addendum: After I wrote the review, I had another flat with these tubes. The tire went completely flat after about 50 miles of riding. It was pumped up at the start to 80 psi. I was not far from the end, so I pumped it up and it held for the next 1/2 hr of riding. It still had good pressure, but the next day it was flat. Upon examining the tube at home, there was a small hole in it. It did not seal, or whatever the mechanics was, it is not able to seal to give you more rides as long as the cause is not fixed. Then you can patch it up as you would any other tube, but I just throw the punctured ones out because they can never be relied on. I am still using these, because they are better than normal tubes for my circumstances and needs. Review: Incredible. Self repaired a large hole and didn't need to replace - There was a huge rip in my tire which caused the tube to end up bursting the hole was probably larger than you would normally get from a puncture and it sealed itself after just a few seconds it was absolutely amazing the tire did not end up deflating all the way despite the large burst in fact I never ended up needing to change the tube I just aired it back up to full pressure and keep using it like that after replacing the outer tire. ## Features - 50% Latex, 50% Rubber - Imported - These are no ordinary bicycle tubes!

Since it's a car. And not a bicycle. **Q: will this work with baby trend tire?** A: It should as long as you buy the right size. I used mine in a baby trend tire. **Q: What is the shelf life of this tube? How long can I keep it in my saddle pack before I have to use it?** A: Tough to say. Box says two years from the date of installation. I just pulled the second tube out of the box ~18 months after I bought them and it came with a hole that formed at a crease in the tube as it was packaged in the box, so I'm already down one out of the gate. **Q: How many comes in the package?** A: It only comes with one tube, and ad says 1 item ## Customer Reviews ### ⭐⭐⭐⭐⭐ Work Well *by D***X on July 18, 2022* I think these are good tubes, but overrated.
