If there was pressure there, all the plastic rings would have been destroyed when I took off the winter wheels this spring...but they were all fine.

Look closely at the Nissan lugs the next time you mount up a stock wheel. Unlike the lugs from the 350Z they don't use the cone seat to really center themselves perfectly. They rely on the washer applying enough torque to hold everything in position once it is centered on the ring.
With your aftermarket wheels they are probably lug centric lugs which will use a cone seat to get everything perfect with the center ring as a guide. I can run my aftermarket wheels with or without the centering rings and it doesn't seem to make a difference. Do that with the stock wheels and you get horrible vibration (spacer without centering ring).
