Alcoa has taken more weight out of its aluminum wheels. The new Alcoa 22.5”x8.25” ULT36x and 22.5”x14” 84U61x and 84U64x are each 3 lb. lighter than previous designs. The ULT36x weighs just 36 lb., while the wide-base offering weighs in at 49 lb.
The lighter-weight wheels were revealed at the Technology & Maintenance Council meetings. Alcoa claims these are the world’s lightest-weight commercial truck wheels, providing fuel savings of up to 0.9 gallons per 1,000 miles traveled when converting from steel. They can be ordered in a Dura-Bright or Dura-Black surface treatment, and with two valve stem openings.
