Yep, 80lbs is a good number. Use a good torque wrench and make sure you tighten them in a star-pattern (not clockwise or counter clockwise). You want to try and pull the wheel to the hub as evenly as possible. Also, make sure you don't have the full weight of the vehicle on the tire when torqueing--you want just enough weight so the tire won't spin. Remember, you're trying to pull the wheel closer to the hub and if the vehicle's dead weight is on the tire, it won't take kindly to being pulled in evenly.
