I check all of the lugs on my aluminum wheels after driving about 100 miles. After that, I may check them once or twice during the summer. I always use a torque wrench because my trailer requires 100 ft lb or torque and my truck requires 150 ft lb. That is pretty tight and I want to make sure I get it right without over tightening. If you over tighten the lugs on aluminum rims, you can distort the rims and that can affect the integrity of the rim. It takes very little effort to do it correctly and can cost so much (or get someone killed) if you do it wrong.
