I forgot to mention: I've added a step in my tire installation recently: I initially inflate to 125psi and then back down to the pressure I actually want. Before tubeless tires and rims, this wasn't necessary. But now it's possible for part of the bead to "duck under," which leaves you with a flat spot. This is a problem even if you are using tubes. A few times now, I haven't gotten the final "pop" from the bead shifting until 120 psi. The added benefit to going to 125 psi is that if you've botched the installation, you'll probably find out right away.
