Sounds like you've gone to lengths to work out whats causing the issue. I highly recommend you change to some different tyres although I've never had the issue you describe.
I did have some Ultremo casings fail a while ago, about 6 tyres actually. They were replaced under warranty and I never had another issue. If you've ever seen a snake thats eaten a rat or a cat thats what the tyre looked like - big bulges in it.
If you want a really tight tyre, get some tubeless tyres from Hutchinson and run them with tubes. They are TIGHT, the bead on them doesn't stretch.
I have... I've just striped the brand new ultremos and put some conti force and Attacks on.
