My experience with the Park self-adhesive patches is that at 110-120psi they tend to fail eventually.
Now, that might be my failure to fit them properly, but when they went there was a pattern in the glue which I could only describe as looking like a wormery. It was as though the air had been exploring all the avenues of least resistance until it finally found a way out.
I don't use them any more - they're quick, but patches aren't too slow either and I've had a higher success rate with those.

Reminds me, I'm out of spare tubes.
