Rear bumper spare tire mounts are cumbersome and ugly. They make it difficult to install bike racks and cargo trays. Plus they add weight and length to your travel trailer. BAL now offers the 'Hide-a-Spare' Tire Storage System that allows you to mount the bulky tire beneath your trailer and out of the way. This system is very easy to mount and if you ever require access to the spare tire, simple to remove. Self tapper screws mount the two plates to the frame for a quick install. A knob and pin are removed to lower the 'Hide-a-Spare' to the ground. It then telescopes out for easier access to the spare tire. Made in the USA. Not retail boxed. Limited One-Year Warranty I-Beam Recessed mount for trailers with I-Beam frames without underbelly enclosure. 72" L x 12"
