So I've been running regular tires at ~40 PSI...which is maybe 6 PSI over the door sticker. Now I've put a pair of Kumho Ecowings on the back at 40 PSI.

So am I now seeing a 10-11% mpg gain on the rear axle?

Since the car is FWD...won't really be able to tell how they handle the wet and so forth at 40 PSI till they are on the front.
