Semi-Truck Maintenance Cost Per Year
Annual planning works best when PM, tires, and irregular repairs are tracked separately and reviewed after each quarter.
Annual budget categories
A yearly maintenance budget should include planned PM, annual DOT-related corrections, tire replacement, wear items, aftertreatment exposure, and a reserve for repairs that do not follow a clean schedule.
- PM and oil service
- Tire replacement and casing decisions
- Brake and wheel-end work
- Aftertreatment and electrical diagnostics
- Unplanned downtime reserve
Sources and Methodology
- Parts plus labor planning methodology - Internal method: estimate likely parts range, labor hours, shop rate, fluids, shop supplies, diagnostics, downtime, and regional variation.
