- Schwalbe Marathon tyre, correctly inflated. Big vicious blackthorn
- Good quality MTB Tyre. Big vicious blackthorn.
- Brand new inner tube, did we nip it, was it a thorn.
Just had the autopsy, and when we removed the tube it was holding air, still had shape. However when we immersed in water it was leaking from the base of the valve, where valve and rubber meet. I suspect that if we had pumped the tyre up it would have got us back to the van (as it went down only 3 miles from the van, I left my wife and just returned to pick her up without mending the puncture)
So not really sure if it was a faulty inner tube from the get go, or possibly we damaged it putting it in, however as we had been quite rough with the valve repairing the Schwalbe, we had been very gentle with this valve, so that would be surprising.
Before we throw the faulty inner tube in the bin, people have mentioned having a bit of inner tube, what's that all about please. Its an MTB one so 2.5 or something.
