Tire Shop Financing: Inventory Depth and Service Capacity

Why inventory depth decides how many sales a tire shop closes

A tire sale often depends on having the right size on the rack when the customer is at the counter. If the size is in stock, the job can go straight into a bay. If it is not, you either order it and hope the customer waits, or the customer goes elsewhere. That is why inventory depth matters so much in a tire shop.

Depth costs money, though, and not all of it works equally hard. Some sizes sell every week, while others sit for months. Before you finance more stock, look at where your current inventory dollars sit by how fast each group turns.

In this illustration, half the inventory turns quickly and could reasonably be financed and repaid from its own sales. The rest turns slowly, and financing more of it adds cost without adding many sales. The goal of inventory financing is to deepen the sizes that sell, not to raise the total on the rack.

Date codes, recalls and supplier liens: what affects stocking decisions

Tire inventory carries some obligations other stock does not. Each tire’s identification number ends in a date code: under federal rules, the first two symbols of the code give the week and the third and fourth give the last two digits of the year of manufacture, so a date code of 0109 means the tire was made in the first full calendar week of 2009. Anyone who reads the tire identification number can see when a tire was made, which is a reason to keep older stock moving.

Federal rules also require independent dealers to give each purchaser a registration form recording the tire identification numbers and the dealer’s name and address at the time of sale, or to send the information to the manufacturer electronically within 30 days. When directed by a recall notification, dealers must immediately stop selling the affected tires. A recall can take part of your inventory off the market with little warning, which is another reason to avoid carrying more slow stock than you need.

Matching inventory and service needs to a financing structure

Tire shops usually have three different needs: keeping the right sizes in stock, covering timing gaps between buying and selling, and adding the equipment that sets how many cars the bays can handle. Each one has a different repayment source.

• Supplier terms first

  Distributor credit terms are often the simplest way to carry inventory. Use them fully before adding financing, and keep the account current so the terms stay available.

• A line of credit for recurring stocking

  A business line of credit can be drawn before a busy stretch and repaid as the tires sell. Interest applies to what you draw, and the line can be reviewed or reduced if results weaken.

• Working capital for a one time buy

  Short-term working capital may fit a defined purchase, such as a large opportunity buy, repaid from the sales it produces. Payments may be daily or weekly.

• Equipment financing for service capacity

  Equipment financing may fit tire changers, balancers, alignment systems and lifts, with the equipment usually securing the agreement.

Keep inventory money and equipment money separate. Buying an alignment machine with a short-term advance repaid in a few months can squeeze cash flow that should be restocking the racks. For more on choosing between the two main structures, see line of credit vs. term loan.

Service capacity: changers, balancers, alignment and TPMS tools

Inventory brings customers in; service capacity determines how many you can finish. A shop with deep stock but one slow tire changer or a backlog at the alignment rack will turn away work at the busiest times. Equipment that removes a bottleneck can pay for itself faster than equipment that adds a second machine nobody is waiting for.

Many vehicles you service will have tire pressure monitoring systems. Federal Motor Vehicle Safety Standard No. 138 applies to passenger cars, multipurpose passenger vehicles, trucks and buses with a gross vehicle weight rating of 10,000 pounds or less, other than vehicles with dual wheels on an axle, and requires a warning when pressure falls 25 percent below the manufacturer’s recommended cold inflation pressure. TPMS tools, sensors and the training to use them belong in your service capacity budget.

Line up equipment offers on the same points: loan or lease, total repayment, whether installation and air or electrical hookups are included, and how far any UCC filing reaches beyond the machine itself. With a lease, the end of the term matters as much as the payment, because the contract decides whether you return the machine, keep leasing it or buy it. Shops that also do general repair can find more on lifts and diagnostics in auto repair shop financing.

What providers may review for a tire shop

There is no universal minimum for tire shop financing; each provider sets its own criteria. Most reviews start with how steadily money comes in and what the shop already owes. Correia Financial begins with your four most recent complete months of business bank statements; providers may then want inventory reports, distributor statements, a profit and loss statement, tax returns or equipment quotes.

If your sales rise and fall through the year, compare equivalent periods and be ready to explain the pattern. See how to present seasonal revenue in an application.

Commercial truck tires: larger inventory and specific rules

Shops that sell and service commercial truck tires carry more expensive stock per unit and need different equipment. The financing logic is the same, but the amounts and the rules change.

OSHA’s rim wheel standard applies to servicing multi-piece and single piece rim wheels on large vehicles such as trucks, tractors, trailers, buses and off-road machines; it does not cover automobiles or LT-marked tires on pickups and vans. Employers must provide a restraining device such as a cage or rack for inflating tires, or for single piece wheels a restraining device or barrier unless the wheel is bolted onto the vehicle during inflation. They must also provide an air line assembly with a clip-on chuck and an in-line valve with a gauge or presettable regulator, and train every employee who services rim wheels.

Federal excise tax on tires is imposed on the manufacturer, producer or importer, at 9.45 cents for each 10 pounds of maximum rated load capacity above 3,500 pounds, or 4.725 cents for biasply and super single tires. When you buy from a distributor, the tax has already been imposed upstream on the manufacturer or importer; if you import heavy truck tires directly, you may owe it as the importer. Ask a tax professional before you plan an import purchase around financing.

What inventory financing costs, compared with supplier terms

Inventory financing has a cost, and it has to be smaller than what the extra stock earns. Compare any offer on the funds you receive after fees, the total repayment, the payment amount and frequency, the estimated APR where one is given, and any lien or personal guarantee.

Revenue based financing works differently: the provider purchases part of your future receivables instead of making a loan, so there is no interest rate to compare. Its cost is the gap between what you repay and what you receive, which you can also express as cost per dollar received. Check its remittance, whether a share of receipts or a fixed amount, against your slowest weeks.

For a fuller comparison, read planning financing before a supplier discount deadline.

When more inventory is not the answer

Financing more tires helps when the shop is losing sales because sizes are out of stock. It does not help when the stock is there and the bays are full, when slow sizes and older date codes already crowd the racks, or when distributor balances are falling behind.

In those cases, the better step may be to clear aged stock, tighten ordering to the sizes that sell, add service capacity, or bring supplier accounts current before taking on a new payment. Already repaying an advance or loan? Read how existing financing shapes a new request before adding another payment.
