CSI Oversized Spare Tire Carrier is manufactured from thick 3/16" cold rolled steel and treated to a dual stage textured black powder coated finish for superior durability, on and off road. It’s designed to attach to the factory tailgate and hold up to a 37" spare tire. It features an adjustable arm that eliminates tailgate sag associated with cheaper oversize tire racks. The Tire Carrier is designed to use a padlock for added security. This rack will not work with factory wheels.
