maybe. a little less weight to turn and im pretty sure they have pretty low rolling resistance. it also seems like my 07 ran just a touch higher rpms on the highway. even a very small improvement in coefficient of drag can make a difference.
I know I will not go through another winter with these awful, awful, awful tires. did I mention they were awful?
