Focus 1
Define the cost scope
Decide whether the calculation includes tire cost, freight, mounting, balancing, repairs, roadside service, casing credits, retreads, disposal, and downtime. Apply the same scope across every comparison.
Lifecycle cost
Measure fleet tire cost per mile with consistent operating data
Cost per mile is useful only when the fleet defines which costs and miles are included. A consistent method helps purchasing, maintenance, and operations compare products and suppliers without hiding freight, service, casing, or early-removal costs.
Focus 2
Capture tire history
Track install and removal dates, positions, vehicles, odometer readings, pressure or inspection history, repairs, rotations, removal reasons, and casing disposition. Missing removal data can distort results.
Focus 3
Compare like applications
Separate results by vehicle class, axle position, route, load, season, and operating region. A tire used in urban delivery should not automatically be measured against one used in long-haul service.
Procurement workflow
Create a repeatable measurement
- 1
Choose the unit of analysis
Measure by tire, vehicle, axle group, product line, route, supplier, or fleet segment according to the decision being made.
- 2
Record complete costs
Use documented purchase, service, repair, and casing transactions rather than estimated totals whenever possible.
- 3
Validate delivered miles
Use consistent install and removal readings and flag missing, transferred, damaged, or prematurely removed tires.
- 4
Review exceptions
Investigate road hazards, alignment, inflation, mechanical wear, overload, and service delays before treating every removal as a product result.
Fleet buyer questions
What to settle before the order
What is the basic fleet tire cost-per-mile calculation?
At its simplest, divide the defined tire-program cost by the miles delivered under the same scope. The fleet should document included costs and how transfers, casings, retreads, and incomplete records are handled.
Why can a lower-priced tire have a higher cost per mile?
Purchase price is one input. Delivered mileage, early removals, repairs, service calls, downtime, casing value, and retreadability can change the lifecycle result.
How often should results be reviewed?
Use a cadence that provides enough completed tire histories for a meaningful comparison. Review serious exceptions immediately, and avoid drawing conclusions from a very small or incomplete sample.
