Based off of my measuring, the wheel specs are:
20x9 +38 (2.25" lip)
20x10.5 +31 (3.75" lip)
Tires: Nexen N3000
245/30/20
285/30/20
The wheels have brushed/cleared centers with a polished lip. The wheels could definitely be refinished, as the clearcoat on the centers is peeling. Since I assume the buyer will have them refinished, I did not bother polishing the lips but that's all it will take for the lips to shine line new. The rear tires should be replaced. The fronts have decent tread left, but 1 tire needs a patch after I removed a nail from it.
I had them on my G35 coupe, but sold the car. I tried fitting them on my Mazda 6, but the rears looked so dumb (see last picture for a laugh).
My asking price takes into consideration the $500 to have the wheels refinished in whatever color you'd like, around $400 for new rear tires, and $20 to plug the 1 front tire.
Asking price: $1800 plus shipping
