A lug wrench, also colloquially known as a tire iron, is the name for a type of socket wrench used to loosen and tighten lug nuts on automobile wheels. In the United Kingdom and Australia, it is commonly known as a wheel brace.
Another common type, sometimes called a spider wrench, is made in the shape of a cross with different sized sockets on each of the four ends. Other names are four way wheel wrench, spanner, brace, or cross.
