Most mechanics are to frickin lazy to properly torque the wheels & then when someone gets a flat on the road & they try to loosen the lug nuts with the crappy factory wrench, they can't.
Factory wrenches couldn't take off a bolt tightened at 5lbs, everyone needs to buy a cross wrench. And I doubt you could damage the mags or the discs by hand tightening bolts.
you could be surprised how easily things can get dammaged on a car. So tomorrow i'm gonna call up the stealershit since you guys can't answer me. thanks.
Now that I'm home, I checked my Tire Guide book that I got from a friend who sells tires. For most Nissan cars, including the Altima, it shows 72 to 87ft/lbs.
