Why Small Fleets Start at a Disadvantage
For small fleets, tires are one of the largest and most frustrating maintenance expenses. A full tire replacement on a highway tractor, which typically has ten tires, often runs between $4,000 and $6,000, depending on brand, spec, federal excise tax, and service costs. For fleets replacing steer, drive, and trailer tires at different intervals, total annual tire spend is often higher than expected because costs show up in smaller, irregular events rather than one planned purchase.
Larger fleets on the other hand get better tire pricing through volume discounts and national programs. They also tend to have dedicated teams to handle maintenance schedules, standardized specs, and systems for tracking tire performance at scale.
Small fleets don’t always have that infrastructure. As fleets grow, even by a handful of trucks, day-to-day inefficiencies compound quickly. Fewer people are directly inspecting tread, rotations get delayed, and inflation checks happen less consistently as attention gets spread thinner.
Small fleets typically have less leverage on per-tire pricing than large national accounts, but cost control doesn’t come from price negotiation alone. Access to the right programs, standardized specs, casing strategy, and service consistency often matter more than chasing the lowest sticker price.
Where Tire Spend Goes Off Track
When small fleets try to work around these constraints, a few recurring patterns can push costs even higher over time.
One pattern is focusing on price per tire instead of cost per mile. A cheaper tire that wears faster, performs inconsistently, or increases fuel drag often costs more over its lifespan than a higher-quality option. Focus on total lifecycle cost using inputs like miles to removal, irregular wear, fuel impact, casing value/retreadability, and downtime likelihood.
Another is missed maintenance basics. Under-inflation, delayed rotations and misalignment all shorten tire life. Running tires 10 psi under can drive ~0.5%–1.0% higher fuel consumption and ~5%–10% tread life loss. These issues don’t always cause immediate failure, but they steadily accelerate wear and force replacement decisions sooner than planned.
Underutilizing retreads is another opportunity left on the table. They’re sometimes dismissed as lower quality, even though modern retreading can significantly reduce cost per mile without compromising safety. Retreads are often the cheapest safe miles when casing quality and processes are good. The U.S. Tire Manufacturers Association notes retreading generates ~$3B in annual cost savings and highlights material/energy savings too.
Finally, inconsistent replacement timing adds to overspend. Fleets often trade off between replacing tires early to avoid downtime and stretching them longer when cash or attention is tight, accepting more risk in the process.
The reason this all matters is tire replacements are unpredictable when wear isn’t tracked. Prices fluctuate, availability varies by location, and many small fleets operate lean enough that one unplanned tire event can disrupt schedules, strain cash flow, and force trade-offs between uptime and cost.
Why Reactivity Is the Biggest Cost Driver
Some of the most expensive tire decisions happen when it’s unclear which tires need attention until a replacement is forced. That lack of visibility doesn’t just affect cost it also carries real operational risk. In 2025, tire-related issues accounted for 21.4% of all vehicle out-of-service (OOS) violations, making tires the second leading cause of OOS violations after brakes.
When decisions are forced, replacements tend to happen at the worst possible time during active routes, under schedule pressure, or when parts availability is limited. That drives higher labor costs, emergency pricing, and unplanned downtime.
More importantly, reactive replacement limits learning. When tires are only addressed once they fail, fleets lose insight into why they failed and what conditions led there. Without that feedback, the same issues are more likely to repeat.
What Small Fleets Can Actually Control
Effective cost control comes from managing tires as part of standard operating procedure, using clear indicators to guide when replacements actually make sense.
That starts with putting basic structure around tire management:
- Standardizing tire specs where possible makes wear easier to compare and replacement decisions easier to plan. Fewer SKUs mean easier rotations, easier casing management, more consistent wear comparisons, simpler roadside replacement.
- Consistent inflation checks, scheduled rotations, and alignment reviews extend tire life more reliably than chasing lower purchase prices. The fuel and tread penalties from underinflation are big enough that this is usually the fastest ROI lever.
- Tracking how long tires actually last in your operation matters just as much. When fleets understand real-world tire life, replacements can be planned instead of rushed—reducing downtime, wasted tread, and cost per mile.
The Bottom Line
Tire overspend isn’t only about buying the “wrong” tire at the “wrong” time. It’s caused by wear being hard to see and replacements being hard to plan.
In small fleets, tire costs escalate not just because tires fail, but because failure becomes the signal instead of the endpoint.
When inspection, maintenance, and replacement decisions happen under pressure, cost per mile rises and downtime becomes more likely.
The goal is to aim for better predictability. When tire performance is measured, maintained, and planned for, tires stop being a recurring surprise and start behaving like a controllable operating cost.
That shift from reacting to failures to managing wear is what effectively lowers total cost per mile and keeps your trucks on the road.
Where to Go From Here
If you do nothing else: follow a simple checklist for tire maintenance and replacement. You don’t need a complex system—just consistency. This level of structure alone can materially extend tire life and reduce forced replacements.
Baseline Review:
- Inflation: Check on a set schedule (not “when someone remembers”)
- Rotations: Plan by miles or inspection intervals
- Alignment: Review at steer replacement or when irregular wear appears
- Specs: Limit the number of tire SKUs where possible
- Tracking: Record install date, position, and removal reason
Measure true cost per mile. True tire cost per mile isn’t just what you paid at purchase. Track CPM by position (steer, drive, trailer) and brand/spec. If two tires cost the same per mile but one fails more often or causes downtime, it’s the more expensive tire in practice.

Use this formula: Tire CPM = (Tire price + FET + mounting/balancing + service calls – casing or retread value) ÷ miles to removal

A rule of thumb for retreads. Retreads work when casings are protected and expectations are clear. The goal isn’t use more retreads but rather to protect casings so retreads are a safe option.
- Steer: New tires only (risk tolerance and wear sensitivity matter most)
- Drive: Retreads when casing history is known and inflation/alignment are controlled
- Trailer: Retreads are often the lowest-cost miles if maintenance is consistent
Connect tires to the bigger system. Tire decisions affect far more than replacement schedules. Share this article with any colleagues in maintenance or dispatch so the choices you make align with uptime, fuel efficiency, and cash planning.
Address volatility where it starts. Fuel is the most frequent operating expense and often the first place volatility shows up. When fuel spend is unpredictable, it limits how proactively fleets can plan maintenance, including tires. The Mudflap Fuel Card helps small fleets stabilize fuel costs and cash flow, creating room to plan tire replacements instead of reacting to failures. Predictable fuel spend supports predictable maintenance and fewer forced decisions across the operation.
