PeterbiltUsing lightweight Alcoa aluminum wheels instead of steel wheels helps decrease truck weight, according to the company. The severe-service wheels are rated at 8,000 pounds, which provides a front-axle weight rating of 16,000 pounds. By accommodating a heavy-duty front axle, customers can spec the same wheels for every axle and stock the same size tires.
