Stupid question of the night. My gas mileage has recently took a turn for the worse again. The only thing I could pin point would be the addition of the 17x11's in place for the stock snowflakes. I know I added alot of tire. Does that effect gas mileage or E.t.'s? I went from 20 mpg to about 16.
Thanks in advance guys!!
