How to organize your tire inventory racks
A rack naming system for rows and positions, why new and used tires need separate rows, and what finally clears the pile in the back.
It's 7:40 on a Saturday and rack B2 has three different sizes piled on top of each other. A customer is waiting on a 225/60R16 take-off that came in Tuesday, and nobody remembers which stack it landed in. That's the moment a rack system either saves you ten minutes or costs you a sale.
A good layout isn't complicated. It just has to be one that every person on the floor, new hire or owner, can say out loud and land in the same spot twice.
Name every rack like a map, not a mood
Use rows A through F and positions 1 through 4, so a tire's home is "B2" or "E4," never "the rack by the door" or "wherever it fit." Reserve a separate letter block for used stock. U1 through U16 covers most one- to three-bay shops and still leaves room to grow. Write the name where everyone can see it: a painted number on the shelf edge, not a sticky note that peels off by July.
The system only works if it's boring. Skip clever names. Boring wins every time. "Big Steve's corner" means nothing to a new hire on day one. "B2" means everything the first time someone finds a tire there.
Keep new and used tires off the same row
New and used tires are different products with different questions attached. Is this a warranty return? Did we grade it? What's the tread left? Mixing them on one row invites the wrong answer to all three.
Give used stock its own rows, even if that's just two shelves near the changer at first. A customer who picks up a used 17-inch off a new-tire row will ask the new-tire price, and now you're explaining a discount instead of closing a sale.
There's a simpler reason too. Techs move fast during a rush. A tech grabbing a tire for a same-day install shouldn't have to double-check whether the one in reach is new stock or a take-off with 6/32" left. Separate rows make that decision automatic instead of something someone has to remember under pressure.
Sort by size, not by brand
Customers ask for a size. They almost never ask for a brand first. "Do you have anything in a 17?" comes up all day. "Do you have any Continentals?" barely comes up at all. Sort your racks by size, and brand sorts itself out once someone's standing in front of the right shelf.
| Row block | Typical sizes | Notes |
|---|---|---|
| A–B | 15–16 in passenger | Highest turnover, keep near the front |
| C–D | 17–18 in passenger | Split by aspect ratio if volume supports it |
| E | 19 in and up, low profile | Lower volume, fewer positions needed |
| F | LT and flotation | 265/70R17, 33x12.50R20 and similar |
| U1–U16 | Used, any size | Grouped by size within the block, not by grade |
Adjust the block sizes to your own volume. A shop that sells mostly 16s and 17s can shrink E and F and grow A through D.
Label it twice
A tire needs two labels: one on the tire, one on the rack. The rack label is the row-position code, painted or printed, at eye level. The tire label can be a paper tag or a printed QR code that pulls up the tire's record when scanned, which starts to matter once more than one person is working the used bay at a time. DuroBay prints these QR labels straight from the add-tire screen, so the tag and the inventory record are the same object from the moment a tire lands on a rack.
Whatever you use, keep the format identical across every tire. A mixed system of some tags, some chalk marks and some "I'll remember it" is not a system. Pick one method in the first week and make it the only method, even if it means relabeling a shelf of tires that already had chalk marks on them.
What to do with the pile in the back
Every shop has one: the corner of take-offs and trade-ins that never made it onto a rack. It grows quietly. A few tires get set down "for now" during a busy week, and a few months later "for now" is a four-foot pile nobody wants to sort. Clearing it doesn't take a special weekend. It takes an hour and two people.
- Pull every tire out where you can read the sidewall.
- Check the size and the DOT on each one.
- Grade it fast: sellable, needs work, or scrap.
- Assign a rack position before it goes back down, never after.
- Log anything staying more than a day so it shows up in a count later.
Skip a step and the pile grows back by Friday.
Racks are only half the system. A shop with racks but no record of what's on them is back to guessing by Tuesday, which is why pairing a rack map with tire shop software built for used tires tends to matter more than the labels themselves. Shops setting this up from scratch might also want the fuller list in how to start a used tire shop.
Common questions
How many racks does a one-bay shop actually need?
Fewer than you'd think. Six to eight positions for new stock and four to six U-rows for used covers most one-bay shops until volume grows. Add positions as you fill the ones you have, not before.
Should used tires be sorted by grade instead of size?
Sort by size first. Grade belongs on the tag and in the record, not as a separate row, because a customer still walks in asking for a 17 before they ask about condition.
What if two sizes barely fit on one rack?
Split the position instead of the row. B2 and a marked B2-used section can share a shelf if the split is labeled clearly and nobody mixes them without relabeling.
Do QR labels replace a written tag?
No. Keep a simple written size and price on the tire itself for anyone glancing at the rack, and use the QR code for the full record: DOT, tread, source, grade.
How often should the rack map get reprinted?
Rarely, once it's set. Reprint only when you add a row or resize a block, and keep the old map posted until every tech has seen the new one.
