Alloy rims are wheels made from a mixture of metals, typically aluminum and magnesium. They are lighter than traditional steel rims, which can improve a vehicle's performance and fuel efficiency. Alloy rims also offer better heat dissipation, reducing the risk of brake overheating during driving. In addition to their functional benefits, alloy rims come in various designs and finishes, enhancing a vehicle's appearance. Many car enthusiasts prefer alloy rims for their aesthetic appeal and the ability to customize their vehicles. However, they can be more expensive than steel rims and may require more maintenance to prevent corrosion.
