Hi my friend,
I must have spent days surfing the net for something different. It seemed every web site had similar wheels (which it could not be otherwise).
I did purchased "new" second-hand mini wheels taken off from a 2011. They're the proper 4X100, 16"X6.5" wide ET:48 (std Scion iQ is 16"X5" ET45). I always considered the iQ 16" std-fitted wheels "custom" cosmetic-wise versus 15" which I'm sure was chewed over for the North American iQ... so I did not want to go to 17" & 18".
There are as many wheel/tire choices as there are individuals on this forum.
My goal was to preserve tire sidewall height for driveability, thus negating very low-profile tires and 17"-18" wheels.
Similar ET48 will also maintain load bearing on components as intended by Toyota. This wider 6.5" similarly positioned (ET 45-48) will or will not accept intended 205 to be (next)
Tires ? Dunlop Direzza DZ101 preferably in 205-50R16 (or 195-50R16 if turning clearances do not allow)

If you're into this, you may enjoy studying different sizes using:
Custom rims, wheel tire packages for your ride - RIMSnTIRES.com
205-50R16 yields almost identical overall measurements to the standard 175-60R16 except in width
The increased width being divided equally (outside and inside) since ET's are the same (ET 45-48)
Should hopefully fit although I have to try; this car has an exceptional turning radius so I assume there aren't an awful lot of clearances when going in circles (steering locked on either sides)
