[QUOTE 5352118, member: 9609"]where the patch is the rubber is double the thickness so it will never take on the same profile as the rest of the tube when over-inflated as in the photo. When in the tyre it will all be the same shape.
Could a tube fail catastrophically whilst in a perfectly good tyre ?
I don't have a date for when that patch was fitted but at a guess I would say 1 to 3 years (6k to 18k miles) and underneath the mess of the disintegrated paper it seems to be in perfect condition.
One thing I find interesting, the photo shows the scratches in the tube where I have rubbed it with sandpaper, however those scratches have all but disappeared under where the paper/foil was (the paper foil would have been an oblong shape that can just be made out)[/QUOTE]
The reason those scratches cannot be seen is because the rubber solution glue has filled the scratches in. The scratches can still be seen where no glue has been spread.
