Hot wheels are commonly offered in steel and aluminum. Steel wheels are available in two pieces, the center or the inner piece and the barrel or the outer component that holds the tire in place. Both are important components that make up a steel wheel. Still is popular because of its durability and easy repair features. As hot and famous as steel types are light weight aluminum wheels. They have greater varieties with greater heat dissipation. Cast aluminum is one of the most common methods to manufacture custom aluminum wheels. Casting can be done by molding molten aluminum into desired shape as it cools down and hardens. Common methods used are high counter pressure molding, low pressure and counter pressure. The method to be used will depend on the weight, strength and finish that the user wants. Lighter and stronger wheels may use the costly method thus it may also demand higher cost.
The car's specific configurations must be taken in consideration in choosing the right wheels. To avoid too much movement, choose wheels with minimum rolling resistance. Wheel Diameter, weight and width affect the driving dynamics and transmission ratio of the car. Bigger wheel diameter is suited for cars with higher over-all gear ratio. It is also an advantage since it provides bigger contact area between the road area and the wheels.
