The tire racks are excellent choices for garage storage, providing plenty of space to keep your tires neatly organised. Sturdy frame: The tire racks consist of steel frames. The steel frames guarantee sturdiness and stability. Strong load capacity: Thanks to the thick material, reinforcement bars below each shelf, and boltless shelving design, the racks have a supreme load capacity. Flexible storage: The layers are height adjustable. Thus, the tire shelves provide ample storage space for different size tires you want to store and always keep your space neat and well-organised. Note: Each product comes with an assembly manual in the box for easy assembly. Warning: In order to prevent overturning, this product must be used with the wall attachment device (delivery does not contain the wall attachment device).
