With corrosion buildup the torque is "false" for all intents and purposes. The corrosion crumbles and wheel is essentially loose.it cannot be properly torqued,and stud is compromised. I have torqued thousands of lug nuts,99.99% with a torque wrench. If i forget to clean a scaly wheel i can feel it isnt right. Pull wheel and sure enough its corroded. this is a non issue with steel wheels.
