Various forms of spare tire racks for pickup trucks have been heretofore provided for supporting a pickup truck spare tire beneath the rear portion of the load bed of the pickup truck. Many of these tire racks are difficult to operate and substantially impossible for a weak or disabled person to operate in the case of a flat tire and the necessity to remove a spare tire from the rack. Also, while some forms of improved racks have been heretofore provided which enable spare tires to be more readily removed from beneath the rear of the load bed of a pickup truck and to be reinstalled beneath the pickup truck load bed, these newer forms of racks may require structural modifications to existing pickup trucks, be limited to specific wheel and tire sizes, or require excessive vertical clearance. Examples of several improved forms of tire racks including some of the general structural and operational features of the instant invention are disclosed in U.S. Pat. Nos. 1,913,835, 2,034,834, 3,175,742, 3,369,683 and 3,435,971.
