I've shed 71lbs with my wheel tire setup and I love all aspects of the change.Wheels are 1" narrower then stock, air pressure same, and coasting is even better. I remember putting 7" wide wheels on a civic and it changed the camber of the suspension,making the rear tires wear on the inside edge, can't remember if coasting was affected. No doubt the width has a big effect in the rain,Narrow is the way to go for fuel economy. Looking to hear more about your efforts RPM,,Roy.
