I hit 85 (scan guage, not speedometer) in my X yesterday and I thought the truck was going to explode because of the unsteadyness/vibrations. Sure it could have gone faster (plenty of power from supercharger) but with the 35's on.... they probably would have come off. Plus i could see the fuel gauge dropping.

Fastest I ever had the balls to go was 110 in my fiancees 3.5 Altima. I will never do it again!
