OK. Let me make sure I understand you correctly. You bought a tube a year ago, installed it yourself, it was good for that complete year and has now burst. And you think it was the tubes fault? Really?
OK. I will buy you some new tubes, no problem. But I will not replace what most likely caused the flat, your tire and rim.
Sure, you can call the tube company and see what they say.
