Exploding inner tubes

[grellboy]

Just bought a new track pump today, but not sure pressure gauge is too accurate, been pumping up and it gets to 60 psi then doesn't seem to move. The max recommended on my Rapid Robs is about 80 psi or so, so don't want to keep pumping in case my tubes explode. This happened to me before when pumping up a tyre and got me wondering, are exploding tubes common or was I just careless/unlucky/stupid?

exploding tubes are common if the tube is pinched or the rim tape is defective or not seated correctly.

Sorry to go slightly off topic, but I purchased a new track pump from "wilko" - Wilkinsons yesterday, only £9.49 and to be honest it is excellent, the guage is spot on, It feels sturdy and solid and well worth purchasing

Or if not placed on the wheel, inside the tyre.

That's the one I bought today! The gauge might not be stuck on 60psi, but due to previous history of ecploding tubes by over pumping didn't dare carrying on pumping to 80 in case they blew up on me again lol!

Think yourself lucky. I once did it with a "Slime" inner tube .... in my living room. Green gunge everywhere. Looked like the library scene in Ghostbusters, with ectoplasm everywhere. Mrs Donger and I agreed this would never happen again. My bike fettling is now confined to the garage.

The tube could get pinched or on the odd occasion your tyre could be too wide for the rim..as said above make sure your rim tape is good as well.

Can I ask (serious question) how you know its "spot on" ?

I double check with a pressure gauge.

Tubes can't explode without the tyre either lifting at the bead or the tube being installed incorrectly in the first place. An explosion by definition means that the tube went outside the tyre, herniated very quickly and then exploded. Often it even goes back inside the tyre before the bead has had time to settle again, leaving you with no clue as to why it exploded.

So, in the light of that, if your tyre is rated to the pressure you want to achieve, pump away. If you are uncertain and hesitant, you may want to inspect the bead once you've reached 60 PSI or so to see if any asymmetry has developed in the tyre, indicating a bead that wants to lift.

When doing these experiments it is best to keep pets, children and spouses in a different room and forewarned. Such an explosion is pretty loud.

Just deflated my tyres to replace tyres and brand new track pump has failed on me. Went for the £10 option from Wilkinsons instead of Joe Blow Topeak at £26. Arse. You get what you pay for I guess. And halfords shuts in two minutes. Double arse.

My Joe blow pump is crap, count yourself lucky

With all this talk of exploding innertubes, and inside the house. Anyone else tested how good their repair was by over inflating?

Mine's packed up too after very little use. Can you get them repaired? I think that some kind of non-return valve has gone iffy. If not, has anybody got a recommendation. Sorry for the thread deflection.
