Frank,

I try to never let anyone touch the wheels on my Vette or PT but if they ever have to, I always loosen them all when I get home and use my torque wrench set at 100 ft lbs to tighten them back down again. As with all aftermarket chrome wheels, it's always a good idea to look at them again at 1000 miles after the initial time. Almost all manufactuers tell you do do this.

To answer your original question, No, never had them come loose by themselves.
