Stackable tyre racks for PCR and TBR tire warehousing

Stop “Lacing” Tires on the Floor. It’s Killing Your Inventory.

In high-volume tire logistics, floor stacking (lacing) is a silent profit killer. It causes bead deformation in the bottom layers, creates a nightmare for inventory picking (LIFO), and is a massive red flag for Fire Marshals. Switch to a dynamic stackable tyre rack system that converts vertical air space into revenue while ensuring zero compression on the tire sidewalls.

The Structural Flaw of Traditional Tire Warehousing

For decades, tire distributors have relied on “barrel stacking” or “lacing” (interlocking tires like a zipper) to maximize container loads. While this works for shipping, it is disastrous for warehousing. Rubber is a viscoelastic material. When a PCR (Passenger Car Radial) tire sits at the bottom of a 20-high laced stack for months, the multi-directional pressure causes flat-spotting and bead deformation. This results in tires that won’t seal properly on the rim, leading to returns and warranty claims before the tire even hits the road.

Furthermore, fixed aisle racking (Selective Racking) is often too expensive and rigid for the seasonal fluctuations of the tire industry. You need a solution that bridges the gap between bulk stacking density and racking selectivity.

Engineering the Solution: PCR vs. TBR Configurations

A “one-size-fits-all” pallet does not exist in tire logistics. The geometry of a low-profile sports car tire differs fundamentally from a heavy-duty truck tire. Our heavy duty stack racks are engineered based on the specific Diameter (D) and Section Width of your inventory.

1. PCR (Passenger Car Radial) Storage Logic

For PCR tires, the challenge is volume. These tires are lighter but numerous. The rack design focuses on storage density.

• Structure: We utilize a “fishbone” or interlaced pattern on the rack base to maximize the number of tires per square foot (typically 40-50 tires per rack depending on size).
• Protection: The four removable posts bear 100% of the load of the racks above. The bottom tire supports zero weight from the upper tiers.
• Accessibility: Racks can be moved by forklift to the loading dock, eliminating manual “lumping” of tires.

2. TBR (Truck & Bus Radial) Storage Logic

TBR tires are heavy (often 100 lbs+ each) and rigid. Manual handling is a major injury risk. The rack design here focuses on load capacity and stability.

• Structure: These racks typically hold tires vertically (tread on the deck) to facilitate easy rolling on/off, or barrel stacked for maximum density.
• Capacity: Reinforced steel bases handle dynamic loads of 2400 lbs (1100 kg) per rack, stackable 4-high.
• Safety: Prevents the “domino effect” of loose vertical storage.

Fire Safety and Insurance Compliance

One of the most critical aspects of tire warehousing is fire code compliance (NFPA 13 in the US/International standards). Large piles of rubber are high-challenge fire hazards.

• Permeability: Unlike solid wood pallets, our metal stack racks feature open mesh or perforated decking. This allows water from overhead ESFR (Early Suppression, Fast Response) sprinklers to penetrate through the stack to the bottom layer.
• Flue Spaces: The inherent design of the posts creates natural flue spaces, preventing the creation of a solid, impenetrable block of fuel.

The Economics of Reverse Logistics (Nesting)

The tire supply chain is circular. You ship full, but what comes back? In a dedicated fleet or closed-loop system, shipping “air” is expensive. Our portable stack system is fully demountable.

Once the tires are unloaded at the retailer or distribution center, the posts are removed, and the bases nest into each other. You can fit the empty racks of 5 trailers into a single return trailer, slashing reverse logistics costs by 80%.
