One thing you might do is use baby powder in your tire and tube. That way when you inflate your tube it will not have a tendency to push your rim strip around. Not only do I put baby powder in the tire, when I inflate the tube, I pump it up just half way, the let out all the air, and then fully pump it up. That way the tube fully seats with no stress areas. I might add that after the rim strip is stuck on take your finger and press baby powder into the surface of the rim strip also.

As an aside to this, there have been threads about glueless patches not working right. I have posted that they work fine for me. Maybe it is the fact that I powder my tires so no stress is put on the tube and patches.
