About this calculator
Tires are one of the more controllable line items in trucking cost per mile, and the math differs sharply between buying new tires versus retreads, and between steer, drive, and trailer positions which wear at different rates. This calculator divides total tire cost (including any recap/retread cycles you plan to run) by expected tread-life miles to get cost per mile per tire, then multiplies by tire count to get a per-truck tire CPM you can plug straight into your overall cost-per-mile calculation.
Worked example
Using the values the calculator loads with:
Inputs
- Cost per new tire: 550 $
- Cost per retread cycle: 180 $
- Expected retread cycles per casing: 2
- Miles per tread life (new or retread): 130000 mi
- Tires on the truck/trailer combo: 18
Results
- Total tire cost per mile (all positions): $0.042
- Cost per mile per single tire: $0.00233
- Total cost per casing over its life: $910
- Total miles per casing (new + retreads): 390,000
What each field means
Inputs
- Cost per new tire ($)
- The cost per new tire used in the calculation, measured in $. Starts at 550 $ so you have a working example on load.
- Cost per retread cycle ($)
- The cost per retread cycle used in the calculation, measured in $. Starts at 180 $ so you have a working example on load.
- Expected retread cycles per casing
- The expected retread cycles per casing used in the calculation. Starts at 2 so you have a working example on load.
- Miles per tread life (new or retread) (mi)
- The miles per tread life (new or retread) used in the calculation, measured in mi. Starts at 130000 mi so you have a working example on load.
- Tires on the truck/trailer combo
- The tires on the truck/trailer combo used in the calculation. Starts at 18 so you have a working example on load.

FAQ
How many retread cycles is realistic?
A quality steer or drive casing run on a well-maintained truck can typically go through 2-3 retread cycles before the casing is retired, though steer tires are retreaded less often industry-wide due to safety conservatism on the front axle.
Why does tire position matter for this calculation?
Steer tires wear differently than drive or trailer tires and often aren't retreaded as aggressively for safety reasons, so run this calculator separately for steer vs drive/trailer positions rather than using one blended assumption for the whole truck.
What drives tread life miles up or down?
Alignment, tire pressure discipline, driving style (hard braking and cornering), and load weight all swing tread life significantly — a poorly aligned drive axle can cut tread life by 20-30% compared to a well-maintained one.
Is buying premium tires worth the higher upfront cost?
Usually yes on a cost-per-mile basis if the tread life improvement outpaces the price premium — a tire costing 15% more that lasts 25% longer wins on CPM even though it costs more at purchase.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
