The heavy-duty tire loft, multi-tire storage unit is a great solution for storing all types of auto and truck tires and seasonal or recreational tires, ATV tires, race tires and wheels. Installation is simple: The master rail attaches to the wall studs on finished or unfinished walls and the support frames attach into the Master Rail. The support frames can then slide left and right (even after installation). The Tire Loft accommodates various tire sizes as the telescopic chrome tubes can be adjusted in width and depth. The Tire Loft is made entirely of strong, durable steel. Adjustable width from 34-inch to 58-inch. Black finish with chrome support tubes. Weight load capacity up to 400 pounds.
