It's been a full week and almost 1,000 miles since I've rotated the tires. All I can say is I actually prefer the way the car drives and handles with the wider wheels at the front. Mileage is pretty much about the same. I thought I would lose some since the motor now has to move heavier wheels, but I'm still getting pretty much the same mileage. This is from my drive a couple of days ago. The battery actually went to 0% while I'm still 3 miles from home, but made it nonetheless.
