Think your weights are back to front for the first two lines. The first pic (13.3kg) looks to be a 6UL rim, the second (13.4kg) looks like a S1 rim

Stiffer sidewalls are heavier?

Interesting! The AD08R's on the 8" probably have about 3mm of tread left as well.

Managed to get under the 60 secs at QR on the sprint today using the AR-1's on 6.5" rims.

205/50/15 NT-01 (8.31" published tread width) on 15x9 6UL 13.6kg.
The other thing that's worth looking at is braking performance with the different wheel widths, have you looked at that data Magpie?
