One thing that I discovered with my i3 is that my EP-500s really don't offer much reduction in rolling resistance above 42 psi. I saw marked reduction in low speed roll-out below that (using recommended pressures), but even up to 50 psi I could not confidently say it wasn't just noise in my data over 45 psi.

So I usually just fill them to 50 psi until they eventually drop below 45 since that also significantly reduces road hazard damage risk to the wheels as well.
