I am bothered by road noise, I have seen here that some people have had success with lowering tire pressure.
Mine were set at 45 psi.
I did a quick experiment, using an iPhone decibel meter app, with iPhone placed on charging pad.
I did the same stretch of road at 50mph, on autopilot, with tire pressure at 45 psi, then at 40 psi.
To remove outliers, I discarded 10% of the loudest samples, and 10% of the lowest samples, and averaged the rest:
45 psi: 68.1 db
40 psi: 68.3 db
I wish I would have had more time to make experiments at various speeds and average multiple tries and multiple phone placements, but the impression I get from this quick experiment is that lowering tire pressure doesn't seem to help with road noise.
