Exploding innertube
Discussion
May have nipped the sidewall of the tube when putting it in?
I usually pump up to 15-20psi and then see if the bead of the tyre is seated all the way round the rim, I used to pump them straight up to full pressure without checking and occasionally five minutes later you could hear the ping as the tyre fully seated itself.

Just changed a slow puncture with a new tube, pumped it up to 100psi...1 minutes later it exploded...is this unusual or have I done something wrong?
If you read the reviews for Conti inner tubes, they are variable quality at best. Puts me off buying them, even though my "preferred" Spesh ones are £5 as opposed to £3.Itsallicanafford said:
Thanks Chaps, i was rushing abit so must have pinched it, will go slower as it really went off with a bang!
It happened to me once on the road bike. Went bang at about 90 psi while inflating. Sounded like a rifle shot and it took the tyre off the rim.
Scared the crap out of me. I’m mostly a mounting biker and anything over 35 psi is uncharted territory.
I had a pair of Cube E-mtbs delivered a couple of months ago, I unpacked them, checked the tyre pressures, wheeled them outside for me and the OH to try and as she was about to get onto hers the rear tube exploded - as above taking the tyre off the rim. Brand new bike, never been used.
Conti tube. Hmmmmm......

The tyre coming off the rim is the cause of a tube blowing like this rather than an effect.Conti tube. Hmmmmm......
Yet another reply of, yes a pinched tube. I did the same with a Michelin butyl tube last year (awesome tubes btw). On the front wheel, while on the maintenance stand, I'd pumped the wheel up on the ground, and as I was getting the tyre past the brakes the tube let go, at most 6 inches from my right ear. My neighbour came round to make sure everything was OK, it was that loud (his house is 200 or so yards away). I have lost a significant amount of hearing as a result too.
Be careful with inner tubes!

Just ended up having to replace both a tube and tyre - 62mm e-bike. Think the gauge on my JoeBlow must be kaput - or doesn't like such large tubes. Just as I hit the 40psi I wanted (max 55) - bang - and it ripped the sidewall of the tyre as well.
I had just replaced the tube (Michelin) as previous attempts to repair a double puncture had failed twice. On a two week old bike.
I have now filled the tubes with Stan's (removable valve centres) rather than going tubeless - fingers crossed. Would like to add a couple more psi after first ride - better find a different tyre gauge first.

I got myself a slow puncture with a Conti 26 Tour Slim (yes, I am running 100 psi 28 mm tyres on an MTB). My own fault for taking of the tyre, I must have snagged it putting it back on. Those 28 mm tyres can be tough to put on, and I'd rather try it at home first, rather than the roadside.
The one time I've had a blowout was after first putting slicks on my MTB, long ago now. After a ride, the bike was outside, and I hear this almighty bang. Turned out, the metal of the rim had given way, and was peeled back like a banana.
At least OP got a fair bit of bang for his buck.

I was having trouble refitting a tyre, kept pinching the tube, put it down to using tyre leavers to get last bit on as I'm too weak to just push it on by hand... I then tried a bit of liquid soap on the inside of the last part of tyre and pushed it on with ease, no pinching.
Never had trouble replacing a tyre before, was the first time on a new wheel.
I may be late to the party but I'll use the soap next time.
