Kenworth is now offering Alcoa Ultra One wheels for its class 8 and medium duty trucks.

The 22.5 inch by 8.25 inch Ultra One wheel is made of the proprietary Alcoa MangaForce alloy and Kenworth says that compared to existing alloy wheels, the Ultra One offers a 17% increase in strength and weighs just 40 pounds.

It maintains a 7,400 pound load and 130 psi inflation rating and is nearly 50% lighter than steel wheels of the same size, according to Alcoa.

The Alcoa Ultra One wheels are available on Kenworth trucks in all of Alcoa’s popular finish options, including Dura-Bright, Dura-Flange, Mirror Polish, Clean Buff and Brush.
