AbstractA disk type wheel has integrally formed air passages that open to the tire and through a central, closed bottom hub. Pressurized air is supplied axially through the bearing to an outlet surrounded by a mounting boss of the wheel bearing. When the wheel is added in conventional fashion to the boss, the central hub forms an air plenum in cooperation with the boss.
