Direct Answer

The best KPIs for tire shops in 2027 will focus on real-time inventory turnover, average profit per tire sold (including mounting and balancing), and customer lifetime value, as data-driven pricing and service bundling become standard. Shops should also track online booking conversion rates and mobile service appointment efficiency, reflecting the shift toward digital and convenience-first retail. Avoid relying on outdated metrics like simple unit sales volume alone.

> TL;DR: Tire shops in 2027 are a mixed-margin retail-plus-service business — tires themselves run 25-32% gross margin while attached services (alignment, brakes, TPMS) run 55-65%. Winning operators measure tires installed per bay per day, alignment attach %, brake attach %, average ticket, fleet account revenue mix, and wholesale cost as % of retail as the six numbers that decide whether a store clears $1.0M-$1.2M in revenue or drifts toward break-even. Monro disclosed a fiscal 2023 gross margin of 33.4%; Mavis runs 1,859 locations; the Modern Tire Dealer "typical" independent runs 26 stores at $3.6M average sales per store. Anything materially under those bars in 2027 is leaving money on the table.

Why Tire Shops Report Differently

A SaaS dashboard built around MRR, NRR and CAC payback is useless on a tire-shop counter. Tire shops are physical-throughput businesses constrained by bay count, technician headcount, wholesale tire availability (now routed through American Tire Distributors for most independents after Monro's wholesale divestiture), and vehicle-mix at the curb. A 6-bay store can physically install roughly 48-72 tires a day and bill roughly 60-90 service hours a day — and that's the actual ceiling. KPIs have to reflect that ceiling.

Tire shops also report two cost-of-goods streams that SaaS founders never see: landed tire cost (a SKU-level number that moves weekly with manufacturer programs from Michelin, Goodyear, Bridgestone, Continental and Cooper) and shop-supply cost (valves, weights, TPMS sensors, alignment shims). The single most-watched KPI in the industry — wholesale cost as percent of retail — exists because retail tire prices are public, comparison-shopped on TireRack and Discount Tire Direct, and therefore have almost no pricing-power upside; the only lever is buying better.

The third reason tire-shop KPIs are different: service attach is the entire profit story. A naked tire sale at 28% gross margin barely covers the $45-65 of labor it takes to mount and balance four tires. The store only makes money when that ticket also carries an alignment ($110-140 retail at 65% margin), a brake job ($280-450 retail at 55% margin), or a TPMS service ($35-60 at 70% margin). Miss the attach and the store loses money on the visit even though revenue looks fine.

The Most Important KPIs, In Depth

1. Tires Installed Per Bay Per Day

Definition: Total tires mounted and balanced in a day divided by the number of service bays operating that day. The single best proxy for throughput utilization.

Formula: Tires Installed Per Bay Per Day = Total Tires Mounted ÷ (Active Bays × Open Hours ÷ 10)

Benchmark (2027): A healthy independent runs 8-12 tires per bay per day on a 10-hour shift; Discount Tire flagship stores benchmark closer to 14-18 because their model is tire-only, no oil changes or alignments competing for the bay. Below 6 per bay per day means either demand or scheduling is broken.

Named-operator example: Discount Tire (1,200+ stores) sustains roughly 16 tires per bay per day by routing complex alignments out and using 1,159 dedicated tire bays per district.

Failure mode: Counting tickets instead of tires — a 4-tire sale and a 1-tire repair both count as one ticket but consume very different bay-minutes.

2. Alignment Attach Percentage

Definition: Percent of 4-tire sales that also include a 4-wheel alignment on the same ticket.

Formula: Alignment Attach % = (4-Tire Tickets With Alignment ÷ Total 4-Tire Tickets) × 100

Benchmark (2027): Best-in-class operators hit 38-45%; the industry median sits at 18-22%; under-trained counter staffs run 8-12%. Every percentage point of attach on a 2,000-ticket-per-month store is worth roughly $2,400 in incremental gross profit per month.

Named-operator example: Les Schwab (515 stores) is widely credited with 40%+ alignment attach driven by their free-alignment-check at every tire purchase and a posted policy of refusing to install new tires on a vehicle outside spec.

Failure mode: Treating alignment as an upsell at the cashier instead of a pre-installation gating step documented with a Hunter HawkEye printout.

3. Brake Attach Percentage

Definition: Percent of vehicles passing through any tire or maintenance ticket that also receive a brake-pad, rotor or fluid service on the same visit.

Formula: Brake Attach % = (Tickets With Brake Service ÷ Total Tickets That Touched Wheels Off) × 100

Benchmark (2027): 15-22% is the strong-operator range; Monro's consolidated service mix implies roughly 18%; independents commonly hit only 6-9% because they lack a standardized digital vehicle inspection (DVI) workflow.

Named-operator example: Mavis Discount Tire (1,859 locations) drove brake attach into the high teens after standardizing on a mandatory wheels-off brake measurement logged in Tekmetric.

Failure mode: Quoting brake work verbally instead of sending a photo-and-video DVI to the customer's phone with measured pad-thickness numbers.

4. Average Ticket (Average Repair Order)

Definition: Total revenue divided by total completed repair orders in a period.

Formula: Average Ticket = Net Sales ÷ Closed ROs

Benchmark (2027): A tire-focused independent runs $420-510 average ticket; a tire-plus-service shop with strong attach pushes $520-640; multi-bay enterprise operators with DVI workflows consistently report $80-$150 higher tickets than the unaided baseline.

Named-operator example: Big O Tires (450+ franchised stores) reports system-wide average tickets in the $485-525 band; Les Schwab sits closer to $580 because of higher commercial mix.

Failure mode: Confusing average ticket with average tire sale — the latter excludes pure-service visits and produces a misleadingly high number.

5. Fleet Account Revenue Mix

Definition: Percent of total store revenue derived from commercial, municipal and rideshare fleet accounts versus walk-in retail.

Formula: Fleet Mix = (Fleet Account Revenue ÷ Total Store Revenue) × 100

Benchmark (2027): Retail-first operators run 5-12% fleet mix; commercial-tilted stores run 25-40%; pure commercial truck-tire dealers hit 60%+. Discount Tire is publicly pushing fleet mix toward double-digit growth across 20-30 incremental markets through its B2B fleet program.

Named-operator example: Pomp's Tire Service (over 230 locations) runs an estimated 45% commercial fleet mix and uses dedicated outside fleet sales reps with quotas tied to active-account count.

Failure mode: Chasing fleet accounts on net-60 terms without a DSO measurement — fleet revenue that takes 75+ days to collect can eat the margin twice.

6. Wholesale Cost as Percent of Retail

Definition: Landed wholesale tire cost divided by the retail price the customer pays, expressed as a percent. Measured at the SKU level and rolled up to the shop level.

Formula: Wholesale % of Retail = (Landed Tire Cost ÷ Retail Tire Price) × 100

Benchmark (2027): Healthy independents on ATD and Myers programs land tires at 68-72% of retail (gross margin 28-32%); strong-buying multi-store operators hit 62-66% (gross margin 34-38%); Monro's consolidated tire-and-service gross margin printed at 33.4% in fiscal 2023.

Named-operator example: Mavis Tire Supply — vertically integrated with its own distribution arm — is widely benchmarked as running tires at roughly 60-64% wholesale-of-retail, the lowest published-class number among national operators.

Failure mode: Tracking gross margin in dollars instead of percent, missing slow 30-cent-per-tire drift as Michelin and Goodyear pricing programs reset quarterly.

7. Labor Productivity Ratio

Definition: Billed service hours per worked technician hour. Measures how much of the technician's clock is actually being sold to a customer.

Formula: Productivity = Billed Hours ÷ Clock Hours

Benchmark (2027): Strong operators hit 115-135% (technicians flat-rate-paid; billed hours exceed clock hours); the median independent sits at 78-88%; under 70% signals either soft demand or chronic comeback rework.

Named-operator example: Bridgestone Retail Operations (the company that owns Firestone Complete Auto Care, 2,200+ stores) reports system-level productivity in the 110-120% range.

Failure mode: Including non-billable lot time (moving cars, sweeping bays) in the productivity denominator and disguising a real productivity problem.

8. Tire-Only Gross Margin Versus Service Gross Margin

Definition: Gross margin tracked separately for tire-line revenue and service-line revenue, because they behave nothing alike.

Formula: Two side-by-side calcs: Tire GM% = (Tire Revenue - Tire COGS) ÷ Tire Revenue and Service GM% = (Service Revenue - Service Parts and Labor Cost) ÷ Service Revenue

Benchmark (2027): Tire GM 25-32%; service GM 55-65%; a store with a blended GM under 38% almost certainly has under-attached service.

Named-operator example: Monro publicly disclosed 33.4% blended margin after fiscal 2023 actions; that blended print is roughly 30% tires + 55% service at a 65/35 revenue split.

Failure mode: Reporting one blended GM number to the owner and obscuring the fact that tires alone are losing money.

9. Same-Store Sales Growth (Comparable Store Sales)

Definition: Year-over-year revenue change for stores that have been open at least 13 months, excluding new openings, closures and acquisitions.

Formula: SSS % = ((Current Period Comparable Revenue - Prior Period Comparable Revenue) ÷ Prior Period Comparable Revenue) × 100

Benchmark (2027): A healthy mature store grows 3-6% same-store in a steady market; a store turning around grows 8-12%; negative comps for two consecutive quarters is a leading indicator that the store needs intervention before it bleeds further.

Named-operator example: Monro has publicly reported negative comps in recent quarters and has explicitly framed strategy around reversing the comp trend.

Failure mode: Treating total revenue as a comp signal and missing that revenue grew only because three new stores opened.

Real Operators

Discount Tire / Discount Tire Direct — privately held, 1,200+ stores, runs an estimated 14-18 tires per bay per day and is the volume benchmark of the industry. Publicly stated double-digit fleet growth target across 20-30 incremental markets.
Mavis Tire Supply / Mavis Discount Tire — 1,859 locations, largest tire dealership in North America by count. Vertically integrated distribution drives wholesale-of-retail to approximately 60-64%.
Monro, Inc. — public (NASDAQ: MNRO), trailing-12-month revenue $1.18B, ~1,285 company-operated stores, fiscal 2023 gross margin 33.4%, divested wholesale to American Tire Distributors.
Les Schwab Tire Centers — 515 stores, widely benchmarked at 40%+ alignment attach and an average ticket near $580 with a strong commercial mix.
Pomp's Tire Service — 230+ locations, ~45% commercial fleet mix, the named example of a commercial-tilted independent.

Failure Modes

Measuring tickets instead of tires — hides the fact that a 1-tire repair ticket consumes the same bay-minutes as a quick alignment.
No DVI workflow — brake attach craters from a possible 18% down to 6-9% because customers never see measured pad thickness.
Blended gross margin only — masks that tires are running 25% when they should be running 30%.
Fleet revenue without DSO discipline — net-60 fleet AR creeps to net-90, gross margin gets eaten by cost of capital.
Quoting wholesale cost from last quarter's price book — Michelin and Goodyear dealer programs reset quarterly; using stale cost overstates margin by 2-4 points.
Counting alignment checks as alignment sales — a free check that the customer declined is not revenue and not attach.

Reporting Cadence

Daily: Tires installed per bay, average ticket, labor productivity, posted at the morning huddle on a printed one-pager.
Weekly: Alignment attach %, brake attach %, fleet revenue mix, reviewed Friday afternoon with the service manager.
Monthly: Wholesale cost % of retail (rolled by SKU and by manufacturer program), tire vs. service gross margin split, store P&L closed by the 5th business day.
Quarterly: Same-store sales comp, fleet account churn and DSO, capital plan for additional bays or alignment racks.

30 / 60 / 90 Day Implementation

Days 0-30: Stand up the measurement stack. Install Tekmetric or Mitchell1 Manager SE with DVI, post a one-page daily KPI board at the service counter, and reconcile wholesale-of-retail on the top 40 SKUs.

Days 31-60: Drive attach. Mandatory printed alignment quote on every 4-tire sale, mandatory wheels-off brake measurement on every visit, and a counter-staff bonus tied to alignment attach % and brake attach %.

Days 61-90: Margin and fleet. Audit pricing against ATD's live cost feed, reset retail on any SKU under 30% gross margin, hire or redeploy two outside fleet sales reps with quotas measured in active accounts (not just revenue), and begin tracking same-store comp monthly.

FAQ

What is the most important KPI for a tire shop in 2027? Tires installed per bay per day is the single most critical operational metric. It directly measures how efficiently you're using your most expensive asset—service bays—and typically ranges from 4 to 8 installations per bay per day in high-performing shops. Anything below 4 often signals underutilized labor or poor workflow.

How do I calculate alignment attach rate and why does it matter? Alignment attach rate is the percentage of tire jobs that also include an alignment service. Top shops aim for 40-60% attachment, as alignments carry 55-65% gross margins and boost average ticket by $80-$150. It matters because it turns a low-margin tire sale into a high-margin service event.

What is a healthy average ticket for a tire shop in 2027? A strong average ticket typically falls between $400 and $700, depending on your mix of tire brands and service add-ons. Shops that consistently hit the upper end of that range are usually selling premium tires and attaching alignments, brakes, or TPMS services on most jobs.

Should I focus on retail or fleet customers for better profitability? Both are important, but fleet accounts often provide steadier volume and predictable revenue. A healthy fleet account revenue mix is 20-35% of total sales; going much higher can compress margins since fleets negotiate harder. The best shops balance retail walk-ins with a few loyal fleet contracts.

What is a reasonable gross margin target for tires alone versus services? Tire-only gross margins typically run 25-32%, while attached services like alignments, brake work, and TPMS repairs run 55-65%. The overall blended gross margin for a successful shop should be 33-40%, with the service mix pulling the average up from the tire-only baseline.

How many locations or sales volume should a typical independent tire shop aim for? The Modern Tire Dealer average for a typical independent is around 26 stores with $3.6 million average sales per location. For a single-store operator, clearing $1.0-$1.2 million in annual revenue is a solid benchmark; anything materially below $800,000 suggests room for improvement in KPI performance.

### 1. Tires Installed Per Bay Per Day

**Definition:** Total tires mounted and balanced in a day divided by the number of service bays operating that day. The single best proxy for **throughput utilization**.

**Formula:** `Tires Installed Per Bay Per Day = Total Tires Mounted ÷ (Active Bays × Open Hours ÷ 10)`

**Benchmark (2027):** A healthy independent runs **8-12 tires per bay per day** on a 10-hour shift; **Discount Tire** flagship stores benchmark closer to **14-18** because their model is **tire-only**, no oil changes or alignments competing for the bay. **Below 6 per bay per day** means either demand or scheduling is broken.

**Named-operator example:** **Discount Tire** (1,200+ stores) sustains **roughly 16 tires per bay per day** by routing complex alignments out and using **1,159 dedicated tire bays per district**.

**Failure mode:** Counting **tickets** instead of **tires** — a 4-tire sale and a 1-tire repair both count as one ticket but consume very different bay-minutes.

### 2. Alignment Attach Percentage

**Definition:** Percent of **4-tire sales** that also include a **4-wheel alignment** on the same ticket.

**Formula:** `Alignment Attach % = (4-Tire Tickets With Alignment ÷ Total 4-Tire Tickets) × 100`

**Benchmark (2027):** **Best-in-class operators hit 38-45%**; the industry median sits at **18-22%**; under-trained counter staffs run **8-12%**. Every percentage point of attach on a **2,000-ticket-per-month** store is worth roughly **$2,400 in incremental gross profit per month**.

**Named-operator example:** **Les Schwab** (515 stores) is widely credited with **40%+ alignment attach** driven by their free-alignment-check at every tire purchase and a posted policy of refusing to install new tires on a vehicle outside spec.

**Failure mode:** Treating alignment as an upsell at the cashier instead of a **pre-installation gating step** documented with a **Hunter HawkEye** printout.

### 3. Brake Attach Percentage

**Definition:** Percent of vehicles passing through any tire or maintenance ticket that also receive a **brake-pad, rotor or fluid service** on the same visit.

**Formula:** `Brake Attach % = (Tickets With Brake Service ÷ Total Tickets That Touched Wheels Off) × 100`

**Benchmark (2027):** **15-22%** is the strong-operator range; **Monro's** consolidated service mix implies roughly **18%**; **independents commonly hit only 6-9%** because they lack a standardized **digital vehicle inspection (DVI)** workflow.

**Named-operator example:** **Mavis Discount Tire** (1,859 locations) drove brake attach into the high teens after standardizing on a **mandatory wheels-off brake measurement** logged in **Tekmetric**.

**Failure mode:** Quoting brake work verbally instead of sending a **photo-and-video DVI** to the customer's phone with measured pad-thickness numbers.

### 4. Average Ticket (Average Repair Order)

**Definition:** Total revenue divided by total **completed repair orders** in a period.

**Formula:** `Average Ticket = Net Sales ÷ Closed ROs`

**Benchmark (2027):** A tire-focused independent runs **$420-510** average ticket; a tire-plus-service shop with strong attach pushes **$520-640**; **multi-bay enterprise operators with DVI workflows** consistently report **$80-$150** higher tickets than the unaided baseline.

**Named-operator example:** **Big O Tires** (450+ franchised stores) reports system-wide average tickets in the **$485-525** band; **Les Schwab** sits closer to **$580** because of higher commercial mix.

**Failure mode:** Confusing **average ticket** with **average tire sale** — the latter excludes pure-service visits and produces a misleadingly high number.

### 5. Fleet Account Revenue Mix

**Definition:** Percent of total store revenue derived from **commercial, municipal and rideshare fleet accounts** versus walk-in retail.

**Formula:** `Fleet Mix = (Fleet Account Revenue ÷ Total Store Revenue) × 100`

**Benchmark (2027):** Retail-first operators run **5-12%** fleet mix; **commercial-tilted stores** run **25-40%**; pure commercial truck-tire dealers hit **60%+**. **Discount Tire** is publicly pushing fleet mix toward **double-digit growth across 20-30 incremental markets** through its B2B fleet program.

**Named-operator example:** **Pomp's Tire Service** (over 230 locations) runs an estimated **45% commercial fleet mix** and uses dedicated **outside fleet sales reps** with quotas tied to active-account count.

**Failure mode:** Chasing fleet accounts on **net-60 terms** without a **DSO** measurement — fleet revenue that takes 75+ days to collect can eat the margin twice.

### 6. Wholesale Cost as Percent of Retail

**Definition:** Landed wholesale tire cost divided by the retail price the customer pays, expressed as a percent. Measured at the **SKU level** and rolled up to the **shop level**.

**Formula:** `Wholesale % of Retail = (Landed Tire Cost ÷ Retail Tire Price) × 100`

**Benchmark (2027):** Healthy independents on **ATD** and **Myers** programs land tires at **68-72% of retail** (gross margin **28-32%**); strong-buying multi-store operators hit **62-66%** (gross margin **34-38%**); **Monro's** consolidated tire-and-service gross margin printed at **33.4%** in fiscal 2023.

**Named-operator example:** **Mavis Tire Supply** — vertically integrated with its own distribution arm — is widely benchmarked as running tires at **roughly 60-64% wholesale-of-retail**, the lowest published-class number among national operators.

**Failure mode:** Tracking gross margin in dollars instead of percent, missing slow **30-cent-per-tire** drift as **Michelin** and **Goodyear** pricing programs reset quarterly.

### 7. Labor Productivity Ratio

**Definition:** Billed service hours per worked technician hour. Measures how much of the technician's clock is actually being sold to a customer.

**Formula:** `Productivity = Billed Hours ÷ Clock Hours`

**Benchmark (2027):** Strong operators hit **115-135%** (technicians flat-rate-paid; billed hours exceed clock hours); the median independent sits at **78-88%**; under **70%** signals either soft demand or chronic comeback rework.

**Named-operator example:** **Bridgestone Retail Operations** (the company that owns **Firestone Complete Auto Care**, **2,200+ stores**) reports system-level productivity in the **110-120%** range.

**Failure mode:** Including **non-billable lot time** (moving cars, sweeping bays) in the productivity denominator and disguising a real productivity problem.

### 8. Tire-Only Gross Margin Versus Service Gross Margin

**Definition:** Gross margin tracked separately for **tire-line revenue** and **service-line revenue**, because they behave nothing alike.

**Formula:** Two side-by-side calcs: `Tire GM% = (Tire Revenue - Tire COGS) ÷ Tire Revenue` and `Service GM% = (Service Revenue - Service Parts and Labor Cost) ÷ Service Revenue`

**Benchmark (2027):** Tire GM **25-32%**; service GM **55-65%**; a store with a blended **GM under 38%** almost certainly has under-attached service.

**Named-operator example:** **Monro** publicly disclosed **33.4% blended margin** after fiscal 2023 actions; that blended print is roughly **30% tires + 55% service** at a **65/35 revenue split**.

**Failure mode:** Reporting **one blended GM number** to the owner and obscuring the fact that tires alone are losing money.

### 9. Same-Store Sales Growth (Comparable Store Sales)

**Definition:** Year-over-year revenue change for stores that have been open at least **13 months**, excluding new openings, closures and acquisitions.

**Formula:** `SSS % = ((Current Period Comparable Revenue - Prior Period Comparable Revenue) ÷ Prior Period Comparable Revenue) × 100`

**Benchmark (2027):** A healthy mature store grows **3-6% same-store** in a steady market; a store turning around grows **8-12%**; **negative comps for two consecutive quarters** is a leading indicator that the store needs intervention before it bleeds further.

**Named-operator example:** **Monro** has publicly reported **negative comps** in recent quarters and has explicitly framed strategy around reversing the comp trend.

**Failure mode:** Treating **total revenue** as a comp signal and missing that revenue grew only because three new stores opened.

- **Les Schwab Tire Centers** — **515 stores**, widely benchmarked at **40%+ alignment attach** and an **average ticket near $580** with a strong commercial mix.
- **Pomp's Tire Service** — **230+ locations**, **~45% commercial fleet mix**, the named example of a commercial-tilted independent.

## Failure Modes

1. **Measuring tickets instead of tires** — hides the fact that a 1-tire repair ticket consumes the same bay-minutes as a quick alignment.
2. **No DVI workflow** — brake attach craters from a possible **18%** down to **6-9%** because customers never see measured pad thickness.
3. **Blended gross margin only** — masks that tires are running **25%** when they should be running **30%**.
4. **Fleet revenue without DSO discipline** — net-60 fleet AR creeps to net-90, gross margin gets eaten by cost of capital.
5. **Quoting wholesale cost from last quarter's price book** — **Michelin** and **Goodyear** dealer programs reset quarterly; using stale cost overstates margin by **2-4 points**.
6. **Counting alignment checks as alignment sales** — a free check that the customer declined is not revenue and not attach.

## Reporting Cadence

- **Daily:** Tires installed per bay, average ticket, labor productivity, posted at the morning huddle on a printed one-pager.
- **Weekly:** Alignment attach %, brake attach %, fleet revenue mix, reviewed Friday afternoon with the service manager.
- **Monthly:** Wholesale cost % of retail (rolled by SKU and by manufacturer program), tire vs. service gross margin split, store P&L closed by the 5th business day.
- **Quarterly:** Same-store sales comp, fleet account churn and DSO, capital plan for additional bays or alignment racks.

**Days 0-30:** Stand up the measurement stack. Install **Tekmetric** or **Mitchell1 Manager SE** with **DVI**, post a one-page daily KPI board at the service counter, and reconcile **wholesale-of-retail** on the top **40 SKUs**.

**Days 31-60:** Drive attach. **Mandatory printed alignment quote** on every 4-tire sale, **mandatory wheels-off brake measurement** on every visit, and a counter-staff bonus tied to **alignment attach %** and **brake attach %**.

**Days 61-90:** Margin and fleet. Audit pricing against **ATD's** live cost feed, reset retail on any SKU under **30% gross margin**, hire or redeploy **two outside fleet sales reps** with quotas measured in **active accounts** (not just revenue), and begin tracking **same-store comp** monthly.

## FAQ

**What is the most important KPI for a tire shop in 2027?**  
Tires installed per bay per day is the single most critical operational metric. It directly measures how efficiently you're using your most expensive asset—service bays—and typically ranges from 4 to 8 installations per bay per day in high-performing shops. Anything below 4 often signals underutilized labor or poor workflow.

**How do I calculate alignment attach rate and why does it matter?**  
Alignment attach rate is the percentage of tire jobs that also include an alignment service. Top shops aim for 40-60% attachment, as alignments carry 55-65% gross margins and boost average ticket by $80-$150. It matters because it turns a low-margin tire sale into a high-margin service event.

**What is a healthy average ticket for a tire shop in 2027?**  
A strong average ticket typically falls between $400 and $700, depending on your mix of tire brands and service add-ons. Shops that consistently hit the upper end of that range are usually selling premium tires and attaching alignments, brakes, or TPMS services on most jobs.

**Should I focus on retail or fleet customers for better profitability?**  
Both are important, but fleet accounts often provide steadier volume and predictable revenue. A healthy fleet account revenue mix is 20-35% of total sales; going much higher can compress margins since fleets negotiate harder. The best shops balance retail walk-ins with a few loyal fleet contracts.

**What is a reasonable gross margin target for tires alone versus services?**  
Tire-only gross margins typically run 25-32%, while attached services like alignments, brake work, and TPMS repairs run 55-65%. The overall blended gross margin for a successful shop should be 33-40%, with the service mix pulling the average up from the tire-only baseline.

**How many locations or sales volume should a typical independent tire shop aim for?**  
The Modern Tire Dealer average for a typical independent is around 26 stores with $3.6 million average sales per location. For a single-store operator, clearing $1.0-$1.2 million in annual revenue is a solid benchmark; anything materially below $800,000 suggests room for improvement in KPI performance.
