Goodyear Self-Sealing Bicycle Tube, 26″ X 1.75/2.125

I don’t want to waste more time returning this and waiting for a new … Really frustrating. I bought two tubes and installed them. One filled with air and the other does not, as if the valve stem is blocked. I have a large compressor, and no amount of pressure or tinkering has helped. I want to ride my bike. I don’t want to waste more time returning this and waiting for a new one that may also not work.Update: I have returned and replaced repeatedly and 3 out of 4 of the exact same type tubes do not fill. I checked my equipment and it works fine on all…

50% worked ok… Product arrived on time, but one of the two leaks out of the box.I installed in the brand new tire I also purchased here on amazon and it leaked.What else can you say…. i read the previous reviews and saw that others had a similar problem,I took a chance and lost..so now i am buying slime to stop the leak…Ok after some serious troubleshooting the valve cores were leaking, a little silicone lube and they worked great, venders can only check so much so I came back to make good on…
