I loaded up the daughter and took her to college. With an estimated 1200lbs (people, dog, gear) on blizzak tires at 35psi, it rode great on the freeway. The overly active body motions were gone and it acted like a big car. On the way home all that fatiguing motion returned but the mileage was better, ha. I am guessing a payload of 800lbs might be where it becomes noticable.
