Constructed from forged aluminum, this wheel delivers exceptional structural strength while significantly reducing weight compared to traditional steel wheels—helping fleets carry more payload without exceeding axle limits. The reduced rotating mass also contributes to improved fuel efficiency and lower brake system stress during long highway runs. Finished in a dual-sided high-polish surface, the Alcoa 823628 wheel maintains a clean, professional appearance while resisting oxidation, road salts, and harsh chemicals. Its hub-pilot mounting design allows the wheel to self-center on the hub, promoting consistent balance, smoother highway operation, and reduced vibration that can accelerate suspension and tire wear.
