The performance benefits of custom wheels should be your answer. In the 1950s and 1960s race car drivers developed lighter magnesium wheels to reduce weight and enhance performance in all form of racing. Magnesium wheels used in modern race cars are often forged to make them stronger and reduce weight. As a result contemporary forged magnesium custom wheels are very expensive. The oxidization problem is the reason you don’t see contemporary custom wheels made of magnesium.
Fortunately for the custom wheel market today manufacturers developed light weight aluminum alloy wheels that provide the strength needed and come in numerous finish options while reducing wheel weight. Trendy wheel finishes include chrome and polished aluminum, plus painted aluminum alloy come in hyper-silver, silver, white, black, gray and Anthracite. While many of us choose aftermarket custom wheels for their good looks, there are many important performance benefits resulting from reducing a wheels weight compared to factory steel wheels.
The additional strength of a custom alloy wheels can notably reduce tire deflection and tire rollover while cornering. You also get increased brake cooling with custom alloy wheels because aluminum alloy is a great conductor of heat. The large mass of the aluminum wheels help dissipate heat from the brakes. One of the most significant factors affecting a car, truck or SUV road holding ability is the reduced weight of custom aluminum alloy wheels over factory steel wheels.
By reducing weight, custom wheels provide improved acceleration and braking. You must also be careful not to exceed the design weight of the original wheels and have the reverse effect by adding larger wheels and tires or aluminum alloy wheels that are gravity cast. Gravity cast aluminum alloy custom wheels are cheaper but heavier and prone to bending. By using a larger diameter wheel with a lower profile tire it’s possible to properly maintain the overall original diameter of your wheel and tire.
