There are two main categories of wheels you can choose from: alloy wheels and steel wheels. Each of them has its advantages and disadvantages, suitable for different purposes. These are the basic information and differences between alloy and steel wheels;
Advantages
The first advantage of alloy wheels is that they are much lighter than steel wheels, thus reducing unsprung mass and allowing the suspension to follow the terrain more closely. This improves the grip and allows better handling of the car. Lightweight also helps reduce fuel consumption or can be made in larger diameter wheels (16’’ and up), so they have higher compatibility with many types of car.
Alloy wheels conduct heat better than steel wheels. Better heat conduction and an open-wheel design can aid in the evaporation of heat from the brakes, improving braking performance under more demanding driving circumstances and reducing the risk of brake failure due to overheating.
What makes people lean to alloy wheels when considering the differences between alloy and steel wheels is that alloy wheels have a much better appearance. Alloy wheels are made by forging and casting, so it allows room for multiple styles and intricate designs and offers freedom for customization (finishing, polishing, painting).
Disadvantages
The biggest problem with alloy wheels is that they are less durable than steel wheels. They are prone to cracks, dents, and curb rashes. And because of this, even the slightest damage on the wheels can tarnish the overall look of the car. They are also harder to repair. Alloy wheels have to be subjected to complex procedures to bring them back to shape.
Due to the complicated manufacturing process, alloy wheels are quite costly. Because they are less durable, the cost of repair is a part of the problem. This is the reason car manufacturers do not use alloy wheels on low-end budget cars to cut the cost and sometimes offer alloy wheels as an optional add-on or included in trim packages.
