Another tip:
Use a quality "clicker type" torque wrench, not the beam bar with pointer. They are not accurate enough. I work at Detroit Diesel Corporation in the Engineering Lab, and we are not allowed to use the beam type torque wrench at all. When you torque your lug nuts, do it in sequential steps...30 ft/lbs, 60 ft/lb, etc. Always going in a criss cross (star) pattern to equalize the clamping force.
Hope this helps,
