Bugger... just spent a good twenty minutes putting two new Vittoria Evo tubes in my 6/13 wheels (the orig Hutchinson tube valves were a bit short for my track pump to latch onto properly) and BOTH of them blew up during inflation - at around 90 psi indicated on the track pump gauge.
So, these two tubes from Wiggle (for a fiver each, sheesh - never happens with my £1 a piece Decathlon tubes) will be heading back to Portsmouth.
I've never, ever popped a tube like this. There are no sharpies in the tyres, the rim tapes are fine, they just ripped apart.
Anyone any idea what may have happened? Will I get a refund/replacement from Wiggle? Any tips for non-bursting inner tubes?

If it was just one I'd say you trapped or pinched the tube during fitting, but that's unlikely to happen twice in a row, especially if you have plenty of tyre-fitting experience. Then I'd say rim tapes, but I don't suppose it's that if they took the same pressure from your previous tubes.

They generally refund or replace without quibble. State on the form that you're sure you fitted correctly and suspect a manufacturing defect (if you really do).

They escaped from the tyres.

Not unless there's an obvious manufacturing defect.
It may seem like a silly question, but was the bead seated properly?
well, it would seem like it wasn't, according to that link. I've never had a problem before though. Although saying that, I've never had very thin tubes and folding tyres before either. Maybe I need to adjust my fitting technique for these highly strung racing jobbies? I'll try for a pair of replacement tubes, and take EVEN MORE care than usual next time!

You might get a refund but it doesn't sound like the tubes' fault to me.
If they did indeed go bang rather than fffssssssssss then some part of them must have been outside the tyre at the time. My guess would be either pinched tubes or the tyre bead lifting. Faults in tubes don't cause bangs.
Some tyres have beads that are quite easy to damage. The bead will then lift once a critical pressure has been reached.

Try it with an old multiply patched tube first. With folding tyres the beads can sometimes lift although they appear correctly seated when the tyre is flat. Pump it up to about 30 psi first then carefully recheck the seating all round. Once the tyre is hard, say 60 psi, carefully check again. The bead should not move again unless, as I mentioned in a previous post, it is damaged. You shouldthen be able to continue to your goal pressure. (But stick cotton wool in your ears and remove the cat from the garage first.)

You're right. With my previous reply I was only thinking fitting wasn't likely to be the cause as it happened with /both/ tyres. But taking twenty minutes is a clue that the OP was struggling, so damage could easily have been done.
But taking twenty minutes is a clue that the OP was struggling,
hmm... that includes clearing out the garage, finding everything, cleaning the cluster, getting oil on my shirt, cleaning inside the forks/stays while the wheels are out, getting the dog out from under the couch after the first bang...
However I have decided it was prolly my fault. Hope those beads aren't damaged, I could do without buying new tyres :-(

Oh, that's fast in that case. It would take me twenty /years/ to clear out the garage (if I had one) :-)

Recently it took me 3 inner tubes to learn this lesson on W's (of this parish) fixie. It was only after being pointed to the above that I started to pay particular attention to how the tyre was seated at various pressures up to the operating one.

'Tis an ill wind that blows no minds.
Do not buy Vittoria tubes, they are IMHO seriously [censored]. I have lost count of the number of times a brand new tube has lost adhesion between valve and the tube itself. This goes for both butyl and latex. I've even had a couple explode on me without them escaping under the bead.
Several manufacturers use the same third world manfuacturer of variable quality. I stick to Michelins or Continentals, they don't use the same plant and I have had far fewer incidents with them, although Continentals have fully threaded valve stems that make pumping up a bit of a chore.
