I do get 1,000 miles per gallon with these wheels at 100 Miles per hour on a flat open road. I am only turning 600 RPM at 100 MPH due to the big wheels.
The big problem is if I get to an overpass I don't have enough power to climb over it.
If my Mustang did not look so good with these color matched wheels I would put the stock 18's back on.
You gotta admit, My big wheels sure do look better then these:
