The 22.5-inch by 8.25-inch Ultra ONE wheel is made of the proprietary Alcoa MagnaForce™ alloy. Compared to its existing alloy wheel, the Ultra ONE offers a 17 percent increase in strength, weighs just 40 pounds for an additional 5-pound weight savings, and maintains the same 7,400-pound load and 130 psi inflation ratings, according to Alcoa. The Ultra ONE wheel also is nearly 50 percent lighter than steel wheels of the same size.
