(1 1/8" = 28.575 mm) And if your problem is occurring on the rim side, when the bike isn't moving no less, it seems the tire is unlikely to be involved.
Yeah, the inner width of 13.6mm is plenty for a 28mm tire. The "700 x 20/23" labelling is nonsense as far as I'm concerned -- it doesn't match any particular rim dimension or the ETRTO recommended tire widths.
That said, wider rims aren't a bad idea for the 28-32mm tires the OP wants to run. Something with a 17mm inner width would be much better, and on some of the newest rims that have a 19mm inner width, a 28mm tire may puff out to 32mm anyway.
