a.Light surface rust on the rim
b.A missing hubcap
c.Mud packed in the wheel well
d.A cracked rim or a wheel with missing, loose, or broken lugs

Cracked rims and missing or loose lug nuts can cause a wheel to separate from the vehicle and are out-of-service conditions. Surface rust, a missing hubcap, and packed mud are housekeeping issues rather than defects that make the wheel unsafe.
