I went for a bike fitting today and the guy that did the fitting was incredibly knowledgeable about all things bikes. He told me that due to the "physics" involved that wheels were 2 to 3 times heavier at speed. Turns out he was talking nonsense!
I wonder where this old wives tale about wheel weight comes from?
a 26inch wheel when spinning at 80 roations per minute (20km/h or 12mph) will have a Centripetal Acceleration of about 5g (G-Force) on the outermost spot. That does not make the wheel "heavier", but due to the gyroscopic effect and air resistance loose ever more energy, when spinning faster.
