In this April 7, 2014 photo, Alcoa's 22.5" aluminum Ultra One Truck Wheel with MagnaForce alloy is on display at Alcoa's headquarters in Pittsburgh. MagnaForce alloy is the first new alloy change in the wheel market since 1968. Proprietary to Alcoa, MagnaForce offers a 17% increase in strength over existing alloys, allowing the 22.5" wheel to weigh 40 pounds, the lightest truck wheel on the market. (AP Photo/Gene J.
