So I guess I was wrong. It looks like even with the 12mm rear spacer (as opposed to the 15mm), the rear tire will still rub on the plastic liner near the rear of the rear fender. I thought that with my measurements it would clear, and even when I backed up a driveway at an angle to compress the rear suspension and it looked fine, I've noticed that the rear tire has in fact rubbed on the plastic liner. I can see lines on the tire and on the plastic liner there is even evidence that it rubs. This only happens very rarely when I have a full load, but my intention was to have a spacer setup that never rubbed under any condition so I suppose the largest spacer you can put on the rear with absolutely no rubbing of any kind ever would be the 10mm spacer.
