For over 70 years, Alcoa wheels have been a trusted brand for aluminum truck and bus wheels. The company was among the first to mass produce forged aluminum wheels in 1948, and now, it offers a wide range of wheels and wheel components for trucks, trailers, buses worldwide. Alcoa’s aluminum wheels offer a lighter, more efficient alternative to steel wheels, resulting in fuel savings and improved mileage.
