For most vehicles, steel is the more common option. Steel wheels are heavier than aluminum and cannot support as much weight per square inch. Aluminum alloy is a lighter and stronger material, able to support more weight and better withstand corrosion. These attributes make steel wheels less expensive but also less durable.
An experimental steel wheel for a car or truck can cost $140 or more. A steel spare wheel for a car can cost $120. On the other hand, aluminum alloy wheels typically run from $400 to $800 per wheel, while a steel spare might cost only $50 to $100.
However, steel wheels have several advantages of their own that go beyond price and durability. One steel wheel can support more than 2,000 pounds, while an aluminum wheel cannot handle weights over 500 pounds. A steel wheel also won't need to be balanced unless it becomes damaged or deformed. Aluminum alloy wheels, by contrast, may need periodic realigning at the tire shop due to normal wear and tear.
All in all, steel wheels are stronger and can support more weight, but aluminum alloy wheels are lighter and may not need regular balancing. This comes to the end of the steel vs aluminum wheels comparison. Now the decision on you which one to choose.
