Turns out Honda went out of it's way to engineer a passive noise cancelling device integrated into each wheel!

Feeling pretty rotten that I've curbed our wheels quite severely, the optional Honda wheels have a cheaper MSRP, and appear to have no covers that make noise rolling around the parking lot (at least running 30.5 PSI), these are a cheaper option that I guess would have the same feature:
08W18-TRT-100
I could get some super light aftermarket wheels for this pricing....
