17" to 19" Wheels/Tires, My Mileage went down.
#16
These are rhetorical posts. I already know 45-62% of the answer, but its that other 38%to 55% I am yearning for. I just used a calculator to figure that out too. Now THAT is funny!

I'm assuming Bandit, that you also know that you probably have increased your tire diameter which also means circumference even if it's only a small amount. Your final drive ratio is not what's in the rear differential but what's on the rear wheels. That changes how your speedometer reads speeds, thus the computer reads mileage, and also how your engine/tranny reacts to the new rear end ratio. It all ties in together.
Try reinstalling your old tires back on the rear only and then see how the acceleration feels and your gas mileage works out. I think you'll notice the difference immediately. Take care,

OP, I know how you feel. When I was younger I went from 15s on a car to 17s that were 10" wide in the rear. Fuel economy & acceleration took a MAJOR hit...
This is the exact reason I'm glad I got these on the car:
Great fuel economy and strong performance... Next set of wheels will be 18s as well. Also, my brakes look a LOT bigger filling in the wheels
