Those look to be pretty lightweight wheels - so I wouldn't be surprised if they're actually lighter than the OEM 17's. That said, the tires are more than likely far heavier than the factory Fuel Maxes. What size tire and what kind of tire are they?I wonder if your mods, especially the 19 inch tires had an impact of fuel economy? I would guess it could have. Made a trip yesterday from Indy area to Fort Wayne and got 52 mpg on way up and then economy dropped on way home to 47 with a strong cross wind. My car is bone stock other than tint. Interesting as well, my last regen was 89 miles, this tank I am at 350 miles and at 20 grams and been very slow since I got fuel. I wonder if my car has winter fuel or if lower temps outside give me more miles per regen? Dramatic difference.
