Utility rack for a pickup truck

The rack for mounting to a vehicle includes horizontal upper and lower cross members. A pair of downwardly disposed mounting posts are mounted on opposite ends of the upper cross member. Where the truck is a pickup truck having a cargo box, the posts fit downwardly into the post holes in the side walls of the pickup truck box. At least one wheel clamp assembly is mounted, at it's an upper end, to the upper cross member and mounted at its lower end to the lower cross member. Each wheel clamp assembly includes first and second opposed facing parallel vertical clamp members defining a wheel receiving space therebetween sized for snug mating on either side of a wheel disposed between the clamp members and the cross members. The clamp members each have laterally aligned apertures therethrough. The apertures are sized and positioned to accommodate a lock bar of a lock, such as a U- shaped lock, journalled therethrough so that the lock bar may be inserted through the spokes of the wheel and so that a U- shaped hasp of the lock may be positioned over upper ends of the clamp members into locking engagement with the lock bar journalled through the apertures. The wheel is thereby releasably locked between the clamp members.
