Has anyone ever had a problem with there lug nuts working them selves loose? The 4x4 shop says it could be the size of the tires and type of rims. Does anyone have a solution to this? Opinions welcome!!!

Are you torqueing them right? I go 100 on mine. What type of rims and lugs do you have? I have my 37's on aluminum rims with cylinder shaped lugs, and my 35's on steel rims with conical shaped lugs, and never had any come loose.
