Because aluminum is significantly lighter than traditional steel, this forged wheel lowers the overall curb weight of your vehicle to allow for more freight on every trip. This weight advantage does not come at the expense of durability, as the one-piece forged construction is specifically engineered to handle the stress of heavy-duty vocational applications. The high-polished exterior provides a mirror-like finish that stays bright and resists the corrosion that typically eats away at painted steel rims. By utilizing a hub-piloted mounting system, the Alcoa 98U637 wheel centers itself exactly on the axle to eliminate the vibrations and uneven tire wear caused by mounting misalignment. These lighter wheel assemblies also dissipate heat more effectively than steel, helping to keep your tires and brake components at safer operating temperatures.
