Well I just went through and re-did all my trips in my fuel log since I wasn't adding the correct % with my old 175/70/13 tires. I also calculated it right for my current tires. Basically all my old mpg readings went up slightly, and my most recent trip went down slightly. From my calculations, the tires on the car now (165/65/14) are 2.9% difference from the stock (165/70/13). So every time I fill up the car and calculate based on the trip, I need to subtract 2.9% of the miles off the trip. I hope I'm doing that right.
