Tire Costs Jump 6.4%, Driver Pay Tops $1 Per Mile for First Time

Why did tire costs spike in 2025?

Tire costs rose 6.4% in 2025 to 5 cents per mile, the sharpest jump in three years, driven by tariffs on natural rubber and rising synthetic rubber prices tied to petroleum. The increase hit specialized fleets hardest, particularly those running 5 to 100 trucks, where operations demand more expensive tires or incur greater wear.

For context, tire costs had been nearly flat the previous two years, rising just 0.1 cents per mile in both 2023 and 2024. The 2025 spike marks a return to cost pressure in a line item that small fleets can't easily negotiate away. Specialized carriers with mid-sized fleets saw higher per-mile tire costs than truckload operators, except at the smallest and largest fleet sizes.

The tariff component traces to duties on natural rubber imports, while synthetic rubber costs moved with crude oil and diesel prices. Fleets that run regional or construction work, where tire wear accelerates, absorbed the increase with no offsetting rate gains in most lanes.

Driver compensation crosses $1 per mile

Combined driver wages and benefits averaged $1.028 per mile in 2025, the first time the industry crossed the dollar threshold. Wages accounted for 81.8 cents, benefits for 21 cents. The total rose 3.3% year over year.

Driver wages grew 2.5% in 2025, trailing the 2.7% inflation rate. That marks the second consecutive year wages lagged inflation. In 2024, wages rose 2.4% while inflation ran 2.9%. Real purchasing power for drivers declined both years.

For a small fleet, the math is straightforward: a driver running 100,000 miles annually now costs $102,800 in wages and benefits before payroll taxes, workers' comp, or any other labor burden. A five-truck operation with company drivers carries over half a million dollars in direct driver compensation before the first gallon of fuel or the first tire rotation.

Benefit offerings varied sharply by fleet size. Nearly all fleets offered health insurance, but smaller operators lagged larger carriers in other benefits. The gap matters for retention in a market where drivers can move to a competitor offering better coverage without changing their home terminal.

What the cost squeeze means for small fleets

The 2025 cost increases landed during the third year of what the source material describes as a freight recession. Spot rates remained soft, contract rates held flat or declined in most lanes, and volume stayed below pre-2023 levels. Small fleets absorbed higher tire and labor costs without corresponding rate relief.

A 10-truck fleet running 1 million miles collectively in 2025 paid $50,000 for tires (parts and labor) and $1.028 million for driver compensation. The tire bill alone rose $3,000 from 2024. Driver costs climbed $32,800. Together, those two line items added $35,800 to the annual operating budget, roughly $3,000 per truck.

Fleets that locked in contract rates in late 2024 or early 2025 carried those commitments through the year, unable to renegotiate as costs climbed. Owner-operators leased to carriers faced the same cost increases but with less ability to pass them through, since their settlements reflect whatever the carrier negotiated months earlier.

The tire cost jump also hit fleets unevenly. Truckload carriers running highway miles saw the industry-average 5 cents per mile. Specialized fleets in the 5-to-100-truck range, which includes many flatbed, heavy haul, and regional operators, paid more. A 20-truck specialized fleet running 2 million miles annually could have seen tire costs exceed $120,000, compared to $100,000 for a similarly sized truckload operation.

Why wages stayed flat in real terms

Driver wages rose below inflation for the second straight year despite the industry crossing the $1-per-mile compensation mark. The disconnect reflects two forces: fleets raised wages to retain drivers and meet minimum competitive offers, but rate pressure prevented wage growth from keeping pace with the cost of living.

Small fleets face a bind. Cutting driver pay risks losing experienced operators to larger carriers or to industries outside trucking. Holding pay flat in nominal terms guarantees turnover. Raising pay faster than inflation requires either higher rates (unavailable in most lanes in 2025) or accepting thinner margins.

The benefit gap between small and large fleets compounds the wage pressure. A driver choosing between two offers at similar per-mile or hourly rates will pick the employer with better health coverage, paid time off, or retirement contributions. Small fleets that can't match those benefits must pay a wage premium to compete, further squeezing margins.

Tariffs and fuel costs drove the tire spike

The 6.4% tire cost increase in 2025 stemmed from two sources: tariffs on natural rubber and higher synthetic rubber prices linked to petroleum. Natural rubber tariffs raised the cost of imported material used in tire manufacturing. Synthetic rubber, derived from petroleum feedstocks, tracked diesel and crude oil prices, which climbed sharply in early 2026 before moderating later in the year.

Fleets running specialized equipment or operating in high-wear environments absorbed the increase with no ability to defer tire purchases. A truck running construction sites or logging roads can't stretch tire life without risking a roadside failure or a DOT violation. The cost is non-negotiable.

The tariff component also meant fleets couldn't shop around for cheaper imports. Duties applied regardless of supplier, and domestic tire production couldn't scale fast enough to fill the gap. The result: a cost increase that hit every fleet, with no workaround.

The $1 driver compensation threshold

Crossing $1 per mile in combined driver wages and benefits marks a symbolic and practical threshold. For small fleets, it means driver labor now rivals fuel as the largest operating cost. A truck running 100,000 miles burns roughly 20,000 gallons of diesel. At $3.50 per gallon (a mid-2025 average in many regions), fuel costs $70,000. Driver compensation at $1.028 per mile costs $102,800, nearly 50% more.

The shift changes how fleets think about efficiency. Fuel economy improvements save dollars per truck per year. Driver retention and productivity improvements save tens of thousands. A fleet that reduces driver turnover from 50% to 25% avoids recruiting, onboarding, and training costs that can exceed $8,000 per driver.

But retention requires competitive pay and benefits, which brings the cost pressure full circle. Fleets that can't raise rates must find savings elsewhere, cut capacity, or accept lower margins. In 2025, many chose the third option, waiting for freight demand to recover.

What changes for a 5-truck fleet

A five-truck operation running 500,000 miles collectively in 2025 faced $25,000 in tire costs and $514,000 in driver compensation. The year-over-year increase: $1,500 for tires, $16,400 for driver pay and benefits, totaling $17,900. That's $3,580 per truck, or roughly $300 per truck per month.

For a fleet operating on 5% net margins (optimistic in a soft freight market), the cost increase consumed the entire profit on $358,000 in revenue. To maintain the same dollar profit as 2024, the fleet needed to either grow revenue by that amount, cut other costs, or accept a thinner margin.

The tire cost spike also hit maintenance budgets mid-year, forcing fleets to choose between deferring other work or pulling from reserves. A fleet that budgeted 4.7 cents per mile for tires (the 2024 average) found itself 0.3 cents short on every mile, a $1,500 gap over 500,000 miles. That's not a rounding error for a five-truck operation.

The driver compensation increase, while more predictable, still required either rate increases (difficult to secure in 2025) or efficiency gains. Fleets that improved utilization, reduced deadhead, or shifted to higher-paying lanes could absorb the cost. Those that couldn't faced a choice: cut driver pay (and lose drivers), cut truck count (and lose revenue), or operate at a loss.
