    If you stuffed the tube into the tire and inflated it, it might have had a small fold in it that got trapped and split.

    When you inflate the tube the first time, you should inflate it slowly and only a little bit, massage the tire to release any kinks or folds, then slowly increase pressure until about half way. Then give it another massage and deflate it. Then you can slowly refill it all the way.

      That’s unacceptable, this is a manufacturer defect and is no way caused by faulty inflation, which isn’t a thing. If it breaks, it was defective, simple as that.

      If you need to do this and this so it doesn’t break, find a better brand.

        Its quite possible to have a pinch in the tube which will fail during inflation. In my experience, thats all brands; a tube simply can’t withstand 100 psi at a pinch point. This failure is not that, however. This is almost certainly a manufacturing defect, as metioned.

          That explains why I kept getting punctures on my old tubes at 90psi 😮 must’ve been fitting them in a dodgy way after previous repairs

            Or as you said, old tubes. Lots of factors, but a good tube will work a fold out unless it’s literally pinched between the rubber and rim.

              I recently patched my tube, and when I inflated it to 40 psi or so, I could hear popping in the tire from the pinches working their way out. And this is despite being careful by preinflating it before putting the tire back on.

              I’ve had the same with new tubes as well. Just be careful when inflating your tube after installing the tire. This particular tear probably could’ve been avoided by preinflating the tube.

          A fold will work itself out, if you pinched it between the rubber or rim, nothing you could do would prevent it from rupturing other than reinstalling it correctly.

      Presumably the process of welding the valve part to the rest of the tube failed for some reason and wasn’t spotted by whatever quality checks they do.

      Schwalbe! That’s why I’m surprised, I’ve never had issues with them.

        That is surprising, Schwalbe stuff is usually pretty solid.

        Switched to their tyres on one of my previous bikes a couple years ago, and was pretty impressed with the smooth quiet rolling, and puncture resistance. Currently running road cruiser greens with their inner tubes

    Always buy more tubes than you think you need. They’re a cheap, disposable part with lots of defects, so it shouldn’t surprise you when you get a lemon. Return this one for a refund.
