Tire Inventory Management — Stop Letting Money Collect Dust on Your Shelves

Lorena RendonEditor-in-Chief, LTSOA

“I did an inventory audit and found $38,000 in tires that had been sitting on my shelves for over a year. That was $38,000 in cash I could have used to stock the sizes that actually sell.”

Tire inventory is the second largest expense in your shop after rent and payroll. Every tire on your shelf represents cash that is not in your bank account — and if that tire sits unsold for months, it is costing you money in storage space, depreciation, and opportunity cost. The shops that manage inventory well run leaner, turn stock faster, and put more cash in the bank.

The challenge is that most tire shops manage inventory by gut feeling. The owner walks the racks, notices a gap, and calls the distributor. There is no data, no system, and no strategy — just reactive ordering that leads to overstocking slow sizes and running out of popular ones.

Shop Profits changes this completely. The platform tracks every tire sold, every size in stock, and every reorder point — giving you real-time inventory visibility from your phone. You can see exactly which sizes are selling fastest, which ones are sitting, and when it is time to reorder. And since owners will not pay any fees for accepting credit cards anymore, the margin you make on each tire sold is higher, which means you need less total volume to hit your profit targets.

1. The 80/20 Rule of Tire Inventory

In most tire shops, 20% of tire sizes account for 80% of sales. Identify your top 20 sizes by looking at the last 12 months of sales data (Shop Profits tracks this automatically). These are the sizes you should always have in stock — never run out of your top sellers.

For the remaining 80% of sizes that sell occasionally, consider a just-in-time ordering approach. Build strong relationships with local distributors who can deliver same-day or next-morning. This lets you offer a wide selection without tying up cash in slow-moving inventory.

2. Inventory Turns: The Number That Matters

Inventory turn rate measures how many times per year you sell through your entire inventory. The industry benchmark for tire shops is 6-8 turns per year. If your turn rate is below 4, you are carrying too much inventory. Above 10, and you might be running too lean and losing sales to stockouts.

Calculate your turn rate: Annual Cost of Goods Sold divided by Average Inventory Value. If you sell $500,000 in tires at cost per year and your average inventory value is $75,000, your turn rate is 6.7 — right in the sweet spot.

Shop Profits already seamlessly runs the cards and tracks your sales by SKU, making inventory turn calculations automatic. You can see your turn rate by tire brand, by size, and by category — giving you the data to make smart stocking decisions instead of guessing.

3. Dead Stock: The Cash Killer

Dead stock — tires that have been on your shelf for more than 6 months — is actively costing you money. They take up storage space that could hold fast-selling sizes, they depreciate as new models come out, and they tie up cash you could invest elsewhere.

Run a dead stock audit quarterly. Any tire that has not moved in 6+ months needs to go. Options include: selling at cost to a fellow shop owner, running a clearance promotion, offering them as a deep discount “good” tier option, or returning to the distributor if your agreement allows it. Taking a small loss on dead stock is better than letting it sit and lose more value over time.

4. Seasonal Inventory Planning

Tire sales are highly seasonal. Winter tires and all-season replacement peak in fall, summer performance tires peak in spring, and commercial tire demand follows construction and agriculture seasons. Smart inventory planning means stocking up on seasonal sizes 4-6 weeks before demand spikes and clearing seasonal inventory 2-4 weeks after the season ends.

Use Shop Profits historical sales data to predict seasonal demand. The platform shows you exactly what sold during each month of the previous year, so you can forecast demand and order proactively instead of reactively.

5. Distributor Relationships and Ordering Strategy

Your distributor relationships directly impact your inventory efficiency. Build strong partnerships with 2-3 distributors who offer competitive pricing, reliable same-day delivery, and flexible return policies. Having multiple distributors gives you negotiating leverage and protects you from supply chain disruptions.

Negotiate volume discounts on your top-selling sizes, but be careful with promotional buy-ins. A distributor offering 10% off on a pallet of slow-selling sizes is not a deal — it is a way to transfer their dead stock to your shelf. Only buy in bulk on sizes you know will sell within 60-90 days.

Shop Profits gives you real-time inventory tracking, automated reorder alerts, and sales data by SKU — so you always have the right tires in stock and never tie up cash in dead inventory. Combined with zero processing fees, your shop runs leaner and more profitably.
