I have pushed mine to 130 and it was still pulling but my foot didn't want to stay on the pedal because all the cars around me were going backwards at about 50 miles per hour, that's a scary scene, and the tires scared me too, the v rated tires are suppesed to run 149max but that means at about 140 or so it's not doing to well so I decided to let go of the 140 marker for now...I have no doubt that the altima can do, and surpass 140 though!!!
