i like the highway feel, quiet, good grip in the corners. had a little rain time and i felt in control.

Your new tire rolling resistance will continue to improve as the tread wears away,and you'll see your highest mpg right at the point where they're worn out.
Also,a new tire undergoes a chemical change within it's 1st 4,000 miles of driving before the rubber stabilizes at it's final coefficient.
