I will most likely be running wan-li, or some other hard china compound since these are summer wheels, won't see much lateral G, and don't need to be sticky at all. As far as tire weights, I won't have any good comparisons until I figure out what factory tires weigh versus the new shoes.

OK, so your OD is about the same, the new wheels are lighter and the new tires may be heavier, the same, or lighter. So your moment of inertia may be slightly better, the same, or slightly worse. You've increased section width by 10mm, but covered some of the frontal area by lowering the car. I predict a slight increase in mileage. Just my humble SWAG at it.
