Walking into the local RV store yesterday was this rim and tire at the front door. I always thought that the people with aluminum /mag type wheels had to keep a closer eye out for loose lug nuts. My thinking was the TV and other cars I own have steel wheels and they don't have a problem with wheels falling off. So I checked my steel wheels once in a while. Not any more! As seen below the wheel is steel. Now I need to find one of those torque wrenches that go CLICK! Another thing to add to the pre-flight check list. Well worth the effort.
