As has been mentioned, check your speedo accuracy and correct for it. 205/55-15's are pretty tall.
Part of the rest could be "new tire syndrome". If you like the feeling of a nice grippy tire, you might be driving a little more aggressively without even realizing it. For reference, my car is wearing 15x7's with 215/45-15's and I still get well over 40 mpg (corrected). |
