Tires can definitely hurt or help mileage. However it may not be as bad as you think. Did you upsize from your previous tires to these? A larger tire travels more distance in one rotation which will cause your speedometer to read lower than your actual speed and the odometer to show less mileage. If you did change tire size getting your speedometer recalibrated will get you an accurate calculation, the superchips tuners are capable of this but that's an expensive buy only for tire size. They are a great boost overall though.

It has gone up since I last looked, from 10.1 to 10.8...so I'm hoping that it does just need a bit of time, maybe a month, to give me a fair indication.
