What is a tire iron?

A tire iron is a tool used for removing and installing lug nuts on a vehicle's wheels. It typically has a long handle and a curved, flat end that fits over the lug nuts. Tire irons are commonly made of steel or other durable materials to withstand the force required to loosen or tighten lug nuts. They are an essential tool for changing a flat tire or performing maintenance on a vehicle's wheels. Some tire irons also have a pry bar or lever arm on one end to help remove stubborn lug nuts.
