How to price used tires: margin, markup and tread bands

A blunt guide to pricing used tires by tread band, with real margin and markup math, pairs and sets, and when a take-off counts as new.

Price a used tire by its tread, not by what you paid for it. That's the whole rule. Everything below is just how to apply it without guessing.

Margin and markup aren't the same number

Mix these up and your prices drift for months before anyone notices.

• Markup = (price − cost) ÷ cost. Buy a tire for $20, sell it for $40, and your markup is 100%.
• Margin = (price − cost) ÷ price. Same tire, same $20 and $40, and your margin is 50%.

Same tire. Same two dollar figures. Different answer depending on which formula you're using, and it matters because most shop owners talk markup out loud and calculate margin in their head without noticing. Pick one, write it down, and use it consistently on every tag in the shop. Mixing the two across different tires is how a shop ends up with prices that don't make sense next to each other, even though every one of them felt right at the time.

Pricing by tread band

Two tires that look almost the same on the rack can be worth ten dollars apart once you measure tread. Here's a worked example for a common size, 225/65R17:

Those exact dollars are one shop's example, not a rule. The rule is that tread comes first in your pricing, ahead of brand, ahead of how clean the tire looks. A worn premium tire and a worn off-brand tire at the same tread depth belong in the same band.

A worked example, start to finish

A trade-in comes in: 225/65R17, tread at 6/32" across all three grooves, no repairs, even wear. That's grade B, per the table above. Two days later another 225/65R17 shows up at 5/32", same grade band, close enough to pair with the first. Priced together, the pair should sell for more than the two singles would separately. The shop is saving the customer a second trip spent hunting for a tread-matched tire, and that convenience is worth charging for. Write both tread numbers on the tag, write the grade on the receipt, and that's exactly what a customer's paying for even if they never see the reasoning behind it.

Why 4/32" is usually the floor

Wet-braking distance grows noticeably below 4/32", which is one reason many shops treat that depth as the line where a used tire stops being sellable, even though the legal minimum in most states is 2/32". Selling down to the legal floor isn't illegal. It's a different risk than most shops want to carry on a tire with no warranty behind it, and it's worth deciding that line before a customer's standing at the counter asking why you won't sell them a tire that's still technically legal.

Pairs and sets carry a premium

A matched pair is worth more than two singles with the same tread, because the customer isn't hunting for a second tire that's close enough on their own. Many shops won't sell a pair with more than 2/32" of difference between the two, which means building one takes real inventory to pull from, not just a lucky match on the rack that day. Price that work in: a matched pair should cost more than the sum of two singles at that tread band, and a full matched set of four more again, for the same reason repeated across every tire. Directional tires and asymmetric tires narrow the pool further, since an arrow or an "OUTSIDE" marking on the sidewall rules out half of what's otherwise a good tread match.

When a take-off is priced like new, not used

A take-off, a tire pulled off a new car at a dealer with almost no miles on it, isn't really "used" the way a trade-in is. If the tread's still in the 10/32"-11/32" range and there's no cosmetic damage, price it close to new, and write "new take-off" on the tag and the receipt so the customer knows exactly what they're buying. Calling it plain "used" undersells a tire that's barely been driven. Calling it "new" without the take-off note overstates it, and either mistake is the kind a repeat customer remembers the next time they need four tires instead of one.

A quick gut check before you tag a tire

• Measure tread first. Every other pricing decision follows from that number.
• Write the grade on the tire and on the receipt, not just in your head.
• Track the source tire in your inventory sheet so you can find its match later if you're building pairs.
• New take-offs get their own line on the price sheet. Don't bury them in "used."

Once you've landed on a price, DuroBay's "Sell" turns that tire into a ticket and "Get paid" writes the receipt without you retyping the number you just worked out. Get the tread band right, and the rest of pricing a used tire is just arithmetic.
