Following president Obama's announcement that heavy trucks would soon come under the microscope for fuel economy after enacting tougher CAFE standards for light cars and trucks, heavy truck manufacturers are looking at almost every possible way to improve efficiency and drop weight without sacrificing capability, which is what these big bruisers live by. One area often overlooked on large trucks are the wheels. Many trucks have stamped steel wheels. While strong and sturdy, they can be very heavy. Alcoa Wheel and Transportation products has unveiled a new line of 9.0x14-inch base wheels that the company claims are the lightest in the industry.
The 14-inch-wide base wheels are designed to replace the dual rear wheels on the rear axle of trucks, and, according to Alcoa, switching to the wide single rear wheels and tires could save as much as 1400 pounds, resulting in lower fuel consumption and incrementally higher payload capacities. The new 9.0-inch base wheels are 3 pounds lighter than their predecessors and can save as much as 50 pounds per wheel compared with a steel equivalent. The wheels are available in several finishes, including clean buff, mirror polish, Dura-Bright, and Dura-Flange. The wheels are available for order now.
