The vehicle wheel must be robust against the required torque generating propulsion, loading from internal pressure, and vehicle weight, as well as the rigors of downforce, turning, braking and road irregularities. Since the first pneumatic tire appeared on an automobile in 1895, they have become an essential part. In the modern vehicle, these wheels generally consist of 2 rim types: low-cost steel-fabricated and eye-catching alloy blended rims. The manufacturing process and atomic structure of each rim composition yields different responses under destructive loading, such as that which results from a vehicle collision.
