3 Tier Tire Storage Racks & Shelving. This storage system is ideal for areas where a lift truck cannot be used. This system is affordable and allows maximizing the space used to store vertically stacked tires. However, it offers little flexibility because it must be anchored to the ground. This system is mostly used to store small quantities of tires or to store clients' tires. Specs: overall size 96"L x 18"W x 96"H; tire quantity 30 to 36; weight capacity 500/tier; 3 tiers.
