Before we got our tires installed we were only getting max of 17-18 MPG highway @ 70 MPH. Maybe folks are not hand calculating this or they are going strictly by the computer? Or...???
If I could get 18+ @ 70MPH highway with my tires, I'd faint.
That said, my leveling kit and tires killed about 2MPG all at once so I realize that. But 20+ MPG highway? Damn, maybe something IS wrong with my rig...
