words of wisdom.
I find that the easiest mpg improvement came when I was driving at cruising speed (50-60pmh)for the majority of my drive.
THe aerodynamic improvements kick in and the larger tires lower the final rpm. Also the engine has warmed up.
If you have short commute or hilly terrian, then it becomes more dependent on driving skills. TIming the lights, coastto stops etc.
just my humble opinion.
