Wider tires and gas mileage

Anyway, the cars are fun to drive and the MPG is caculated by the spirit of the drive multiplied by the pressure of the foot.

Heh, that's good.

Yea, the GPS I was using tracked miles over ground and speed. I'm not crazy enough to try to manually determine an accurate miles traveled by time and speed of GPS , though I guess that might not be too bad if you can maintain a set speed.

Welp, this one has been figured out.

Bad gas. Once I ran that tank out, mileage came back in line. Got 26-27 on a trip by the tripminder on Friday. It sits at 24.3 after running around here for a couple days.
