Taurus · 11-17-2016, 10:15 PM

Hello, I am new here and have a few questions: my 2004 Ford Taurus revs kind of high on the express way so I am wondering if a taller tire will help. I know this might throw off my speedometer slightly, but I will adjust my speed accordingly. I have the Duratec engine and it makes great low end torque. I also am aware of possible worse gas mileage in city driving, but thats fine. A taller tire changes the effect of the gearing, and offers less rolling resistance, but will it help mpg in my case?
